Using neutron crystallography, researchers at Pacific Northwest National Laboratory (PNNL) and their colleagues at Oak Ridge National Laboratory (ORNL) have shown for the first time precisely where the hydrogen halves end up in the structure of a molecular catalyst—an iron hydrogenase inspired by a natural hydrogenase enzyme—that breaks down hydrogen. A paper on their study is published in Angewandte Chemie International Edition.
The view confirms previous hypotheses and provides insight into how to make the catalyst work better for energy uses—i.e., for fuel cells—as an alternative to platinum.
DOE releases five-year strategic plan, 2014-2018; supporting “all of the above” energy strategy
April 08, 2014
The US Department of Energy (DOE) released its five-year 2014-2018 Strategic Plan. The plan is organized into 12 strategic objectives aimed at three distinct goals: Science and Energy; Nuclear Security; and Management and Performance. These objectives represent broad cross-cutting and collaborative efforts across DOE headquarters, site offices, and national laboratories.
The overarching goal for Science and Energy is: “Advance foundational science, innovate energy technologies, and inform data driven policies that enhance US economic growth and job creation, energy security, and environmental quality, with emphasis on implementation of the President’s Climate Action Plan to mitigate the risks of and enhance resilience against climate change.” Under that, the plan sketches out 3 strategic goals:
California ARB posts final modifications for ZEV rule on fast refueling/battery exchange for public comment
April 05, 2014
The staff of the California Air Resources Board (ARB) has posted for public comment current final modifications for the Zero Emission Vehicle Regulation for 15 days. (Earlier post.) Statutorily, depending upon the comments received, ARB staff may either make further modifications and resubmit to Board for further consideration; failing that, the Board will adopt the new regulatory language.
These final tweaks to the ZEV rule involve the allocation of ZEV credits for different types of ZEV vehicles and the handling of the associated fast-refueling accreditation, which includes the possible use of battery-swapping.
Partners launch $51M hydrogen fuel cell vehicle and infrastructure project in Europe
April 03, 2014
Automakers, hydrogen fuel suppliers, the Mayor of London’s Office and energy consultancies launched the £31-million (US$51-million) European HyFive project at City Hall in London. Five different manufacturers will deploy a total of 110 hydrogen fuel cell vehicles at several European locations (Bolzano, Copenhagen, Innsbruck, London, Munich, Stuttgart) and develop new clusters of hydrogen refueling stations.
Locations are being sought for three new hydrogen refueling stations in London, one in Aarhus and in Odense (Denmark) and one in Innsbruck (Austria). They are expected to be operational by 2015, by which time some of the manufacturers in the partnership will have started to put hydrogen fueled cars on sale in some European markets.

Europe’s Joint Research Centre (JRC) and its partners in the JEC Consortium—JRC, EUCAR (the European Council for Automotive R&D) and CONCAWE (the oil companies European association for environment, health and safety in refining and distribution)—have published a new version of the Well-to-Wheels Analysis of Future Automotive Fuels and Powertrains in the European Context. (Earlier post.)
The updated version includes a longer-term outlook by expanding the time horizon from 2010 and beyond to 2020 and beyond. It adds an assessment of electrically chargeable vehicle configurations, such as plug-in hybrid, range extended, battery and fuel-cell electric vehicles. It also introduces an update of natural gas pathways, taking into account the addition of a European shale gas pathway. Furthermore, biofuel pathways, including an entirely new approach to NOx emissions from farming, were thoroughly revised.
SAE taskforce completes two technical standards on hydrogen refueling; harmonizing the global infrastructure
March 24, 2014
To support the impending roll-out of hydrogen fueling infrastructure and Fuel Cell Electric Vehicles (FCEV), SAE International’s Fuel Cell Standards Taskforce has completed two technical standards: SAE J2601, “Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles”; and SAE J2799, “Hydrogen Surface Vehicle to Station Hardware and Software”. The standards have been created to harmonize hydrogen fueling worldwide for both 35 MPa and 70 MPa pressures.
J2601. SAE J2601 (also with J2799) fuels fuel cell vehicle hydrogen storage systems quickly to a high state of charge (SOC) without violating the storage system operating limits, explained Jesse Schneider, Sponsor of both Standards SAE J2601 & J2799, in a presentation at the SAE 2014 Hybrid & Electric Vehicle Technologies Symposium earlier this year. SAE J2601 defines parameters for a hydrogen fueling experience similar to conventional fueling and is considered one of the key standards required for the commercialization of fuel cell vehicles and hydrogen stations.
Study finds no benefit to delaying or weakening ZEV policies to drive transition to electric drive
March 14, 2014
A study by a team from the Howard H. Baker Center for Public Policy at the University of Tennessee, Knoxville and Oak Ridge National Laboratory concludes that starting the California ZEV (Zero Emission Vehicle) mandates five years earlier or doubling their intensity increases upfront costs but also increases benefits by a greater amount.
Similarly, the study found, delaying the ZEV mandate is estimated to reduce upfront costs, but cause an even greater reduction in the present value of benefits. Even using pessimistic assumptions about future costs of electric drive technologies, the study showed no net benefit to delaying or weakening ZEV requirements. The simulations also show the important synergies between California and US transition policies, the authors noted.
Toyota continues to prepare the market for fuel cell vehicle in 2015
March 11, 2014
Toyota Motor continues to lay the foundation for the introduction of its production fuel cell hybrid vehicle in 2015; the company began work on fuel cell technology in 1992. Showcased at the Consumer Electronics Show in January in Las Vegas (earlier post), the FCV Concept, which presages the introduction of the series-production vehicle, made its European debut at the 2014 Geneva Motor Show.
Re-emphasizing the general technology points that have emerged over the past few months at different events while adding a bit more detail, Yoshikazu Tanaka, Product General Manager of the Product Planning Group, said at the Geneva show that Toyota’s current fuel cell (FC) system features an output power density of 3.0 kW/L—twice as high as that of its previous FCV, the Toyota FCHV-adv (earlier post). The output power is more than 100kW, despite significant unit downsizing.
DOE to issue funding opportunity for hydrogen and fuel cell Incubator projects
March 07, 2014
The US Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) intends to issue, on behalf of its Fuel Cell Technologies Office, a Funding Opportunity Announcement (FOA) entitled “Innovations in Fuel Cell and Hydrogen Fuels Technologies” (DE-FOA-0001094) for the FCTO Incubator program.
EERE has established multi‐year plans and roadmaps, with a concomitant focus of the majority of its resources on a limited number of “highest probability of success” pathways/approaches to ensure that the program initiatives are supported at a critical mass (both in terms of dollars and time) for maximum impact. While this roadmap‐based approach can be a strength, it can also create challenges in recognizing and exploring unanticipated, game changing pathways/approaches which may ultimately be superior to the pathways/approaches on the existing roadmaps.
Researchers at Berkeley and Argonne labs discover highly active new class of nanocatalysts for fuel cells; more efficient, lower cost
February 28, 2014
A team led by researchers at Berkeley and Argonne National Labs have discovered a new class of bimetallic nanocatalysts for fuel cells and water-alkali electrolyzers that are an order of magnitude higher in activity than the target set by the US Department of Energy (DOE) for 2017.
The new catalysts, hollow polyhedral nanoframes of platinum and nickel (Pt3Ni), feature a three-dimensional catalytic surface activity that makes them significantly more efficient and far less expensive than the best platinum catalysts used in today’s fuel cells and alkaline electrolyzers. This research, a collaborative effort between DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Argonne National Laboratory (ANL), is reported in the journal Science.
Sandia Labs project team building fuel cell cold ironing system for deployment at Port of Honolulu in 2015
February 25, 2014
A Sandia National Laboratories project team, including a number of industry partners, is designing and building a cold-ironing fuel cell system that will be deployed in the Port of Honolulu in 2015. The work comes on the heels of last year’s study and analysis that confirmed the viability of hydrogen fuel cells to provide auxiliary power to docked or anchored ships. (Earlier post.)
Hydrogen researchers at Sandia National Laboratories joined with several partners in the follow-up project, which will result in a portable, self-contained hydrogen fuel cell unit that can float on a barge, sit on a dock or be transported to wherever it’s needed to provide electrical power. The unit will fit inside a 20-foot shipping container and will consist of four 30-kilowatt fuel cells, a hydrogen storage system and power conversion equipment.
Update on Honda/GM fuel cell partnership; “It’s about cost reduction”
February 21, 2014
In July 2013, General Motors and Honda announced a long-term, definitive master agreement to co-develop next-generation fuel cell system and hydrogen storage technologies, aiming for the 2020 time frame. (Earlier post.) At the SAE 2014 Hybrid & Electric Vehicle Technologies Symposium, Mark Mathias, Director, Fuel Cell R&D for GM, provided an update on the collaboration, as well as a brief dive into the technical drivers behind the ongoing automotive efforts on fuel cell propulsion related to the scaling properties of batteries and fuel cells.
The GM/Honda partnership is about cost reduction, Mathias said. “We have vehicles now that work and can be durable, it’s really now about making a business out of the technology. Obviously it involves both the vehicle and the infrastructure and the hydrogen supply, so there are a lot of elements to this.”
NREL initial report on performance of BC Transit fuel cell electric buses
February 17, 2014
Researchers from the National Renewable Energy Laboratory, commissioned by the California Air Resources Board (ARB), have issued their initial evaluation of the hydrogen fuel cell buses in operation at BC Transit. The report covers two years of revenue service data on the buses from April 2011 through March 2013.
In 2012, NREL developed a guideline for evaluating the technology readiness level (TRL) for fuel cell electric buses (FCEBs). TRLs range from concept design at TRL 1 up to full commercialization and deployment at TRL 9. Using this guide, the NREL team assessed the BC Transit buses to be at TRL 7: full-scale validation in a relevant environment. During the two-year data period analyzed for the report, the FCEB fleet accumulated more than 2.1 million kilometers (1.3 million miles) and more than 156,000 hours on the fuel cell power plants. Overall the FCEBs have an average fuel consumption of 15.48 kilograms of hydrogen per 100 kilometers. This equates to a fuel economy of 4.53 miles per diesel gallon equivalent (mi/DGE). The buses have an average availability of 69%.
Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS
February 11, 2014
The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. The Air Resources Board is required to update the Scoping Plan every five years.
Among the actions proposed or considered in the transportation sector include aggressive implementation of the light-duty Zero Emission Vehicle standard; LEV IV emissions regulations for the light-duty fleet post-2025 (GHG reductions of about 5% per year); Phase 2 GHG regulations for medium and heavy-duty (MD and HD) vehicles; a possible ZEV regulation for trucks; more stringent carbon reduction targets for the Low Carbon Fuel Standard; and others.

Toyota opens CES with strong affirmation of hydrogen fuel cell vehicles; “staggering” rate of cost reduction; FCV on sale in US in 2015
January 07, 2014
Toyota opened the 2014 Consumer Electronics Show (CES) with a strong affirmation of the benefits of and potential for hydrogen fuel cell technology. “We aren’t trying to re-invent the wheel; just everything necessary to make them turn,” said Bob Carter, senior vice president of automotive operations for Toyota Motor Sales (TMS), USA, Inc. “Fuel cell electric vehicles will be in our future sooner than many people believe, and in much greater numbers than anyone expected.”
Toyota showcased both its latest fuel cell vehicle concept (the FCV Concept, earlier post), showing what the four-door mid-size sedan will look like in Radiant Blue; and the camouflage-taped engineering prototype used for extensive and extreme on-road testing in North America for more than a year. The prototype has consistently delivered a driving range of about 300 miles (~500 km), zero-to-sixty acceleration of about 10 seconds, with no emissions other than water vapor. Refueling of its hydrogen tanks takes three to five minutes.

January 03, 2014
|WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. Click to enlarge.|
A comprehensive analysis of well-to-wheel (WTW) primary energy demand and greenhouse gas (GHG) emissions for the operation of conventional and alternative passenger vehicle drivetrains in Switzerland has concluded that alternative combustion fuels—not only alternative drivetrains such as PEVs or FCVs—play an important role in the transition towards low-emission vehicles.
The study by a team at the Swiss Federal Institute of Technology Zurich, reported in the Journal of Power Sources, is novel in three respects, the researchers said. First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains. Second, it is specific to Switzerland. Third, the analysis offers a novel comparison of drivetrain and energy carrier production pathways based on natural resource categories.
Tsinghua team develops zinc-air fuel cell stack with high power density
December 29, 2013
Researchers at Tsinghua University have developed a high-power-density zinc-air fuel cell (ZAFC) stack using an inexpensive manganese dioxide (MnO2) catalyst with potassium hydroxide (KOH) electrolyte. As reported in a paper in the Journal of Power Sources, they achieved peak power in a ZAFC stack as high as 435 mW cm-2.
They also reported that the time required for voltages to reach steady state and for current step-up or step-down are in milliseconds, indicating that the ZAFC could be applied to vehicles with rapid dynamic response demands.
DOE releases three reports showing strong growth in US fuel cell and hydrogen market
December 20, 2013
The US Department of Energy (DOE) released three new reports showcasing strong growth across the US fuel cell and hydrogen technologies market. According to these reports, the US continues to be one of the world’s largest and fastest growing markets for fuel cell and hydrogen technologies. In 2012, nearly 80% of total investment in the global fuel cell industry was made in US companies.
The three reports are (1) the 2012 Fuel Cell Technologies Market Report, which describes data compiled in 2013 on trends in the fuel cell industry for 2012 with some comparison to previous years; (2) States of the States, Fuel Cells in America 2013, which provides an updated snapshot of fuel cell and hydrogen activity in the 50 states and District of Columbia; and (3) 2013 Pathways to Commercial Success: Technologies and Products Supported by the Fuel Cell Technologies Office, which updates the results of an effort to identify and characterize commercial and near-commercial (emerging) technologies and products that benefited from the support of the Fuel Cell Technologies Office (FCTO) and its predecessor programs within DOE’s Office of Energy Efficiency and Renewable Energy.
DOE awarding $7+ million to four hydrogen and fuel cell projects, including fuel cell delivery trucks
December 17, 2013
The US Department of Energy (DOE) is awarding more than $7 million to four projects that will help bring cost-effective, advanced hydrogen and fuel cell technologies online faster for both mobile and stationary applications.
Private industry and DOE’s national laboratories have already helped to reduce automotive fuel cell costs by more than 50% since 2006 and by more than 30% since 2008. Fuel cell durability has doubled and the amount of expensive platinum needed in fuel cells has fallen by 80% since 2005. Building on this progress, the new projects will help further reduce the cost of hydrogen and fuel cell technologies, expand fueling infrastructure and build a strong domestic supply chain in the United States. These projects include:

December 11, 2013
|Symbio ALP-5 range extender. Click to enlarge.|
The Franche-Comté region and La Poste (the French postal service) are testing hydrogen fuel cell range extender kits from Symbio FCell in three Renault Kangoo Z.E. electric mail delivery vehicles under real working conditions. This system is expected to double the range of the electric cars used for postal delivery.
The three Kangoos Z.E.s with fuel cell range extenders (HyKangoos) will be deployed in the first quarter of 2014 on mail delivery platforms. These vehicles, with a combination of a hydrogen fuel cell and batteries, offer an extended range that performs under demanding conditions: mail routes of 100 km (62 miles) or more through the cold, hilly and mountainous terrain. (The Franche-Comté region borders on Switzerland, with the Vosges mountains to the north and the Jura to the south.)
Ballard signs MOU with Van Hool for further fuel cell bus deployments; next-gen FCvelocity-HD7 power module
December 06, 2013
Ballard Power Systems has signed a non-binding Memorandum of Understanding (MOU) with Van Hool NV, Europe’s fourth largest bus manufacturer, in support of the manufacture and further deployment of fuel cell buses. By February 2014, the companies plan jointly to respond to last week’s call for proposals under the EU Hydrogen Fuel Cell Joint Undertaking, and also plan jointly to respond to other future calls for proposals under the Horizon 2020 program. (Earlier post.)
For the newly funded buses, Ballard will deliver its next-generation fuel cell power module to Van Hool for incorporation into hybrid bus platforms. This new FCvelocity-HD7 power module will offer improved durability and reliability along with significant cost reduction. (Earlier post.)
Study suggests fuel cell hybrid with supercapacitors for energy storage the most fuel efficient
December 02, 2013
An evaluation of different fuel cell hybrid electric vehicle (FCHEV) powertrain designs—such as fuel cell/supercapacitor (FC/SC), fuel cell/battery (FC/B), and a combination of supercapacitors and batteries (FC/SC/B)—and different control strategies by researchers in Belgium concluded that the FC/SC HEV has slightly higher fuel economy than the FC/B HEV and FC/B/SC HEV powertrains.
This, the researchers suggested in a paper presented at the recent EVS 27 conference in Barcelona, was due to the use of the efficient supercapacitors for the majority of the transient-power requirements (the SC can be charged or discharged at a high current, at which the battery cannot function). The fuel economy of the supercapacitor fuel cell hybrid, they noted, is higher despite the vehicle being heavier and more expensive.

|Toyota FCV Concept. Click to enlarge.|
Toyota confirmed that it will display its latest fuel cell vehicle concept along with four other world premiere future mobility concepts at the upcoming Tokyo Motor Show. The Toyota FCV Concept is a practical concept of the fuel cell vehicle Toyota plans to launch around 2015 as a pioneer in the development of hydrogen-powered vehicles. The vehicle has a driving range of at least 500 km (311 miles) and refueling times as low as three minutes, roughly the same time as for a gasoline vehicle.
The Toyota FC Stack has a power output density of 3 kW/L, more than twice that of the current “Toyota FCHV-adv” FC Stack, and an output of at least 100 kW. In addition, the FC system is equipped with Toyota’s high-efficiency boost converter. Increasing the voltage has made it possible to reduce the size of the motor and the number of fuel cells, leading to a smaller system offering enhanced performance at reduced cost.

The largest award from APC is $8,928,200 to the McMaster University-Chrysler partnership (earlier post) for the development of next generation electrified powertrains. (Earlier post.) However, the selected projects include a range of technologies from hot stamping of parts to hydrogen fuel cell stacks.
Governors of 8 states sign MoU to put 3.3M zero-emission vehicles on roads by 2025; 15% of new vehicle sales
October 24, 2013
The governors of 8 states—California, Connecticut, Maryland, Massachusetts, New York, Oregon, Rhode Island and Vermont—have signed a memorandum of understanding (MoU) to take specific actions to put 3.3 million zero emission vehicles on the roads in their states by 2025, along with the refueling infrastructure required to support those vehicles. Zero-emission vehicles include battery-electric vehicles, plug-in hybrid-electric vehicles, and hydrogen fuel-cell-electric vehicles; the technologies can be applied in passenger cars, trucks and transit buses.
The 3.3 million ZEVs would represent a new vehicle market penetration for the group of states of about 15%, said Mary Nichols, Chairman of the California Air Resources Board (ARB), during a conference call announcing the agreement. This multi-state effort is intended to expand consumer awareness and demand for zero-emission vehicles. Collectively, the eight signatory states represent more than 23% of the US car market.
Tesla leads with transfer of ZEV credits for year ending 30 Sep 2013
October 17, 2013
|Tesla by far dominated the transfer of ZEV credits in California in 2012. Data: ARB. Click to enlarge.|
Between 1 October 2012 and 30 September 2013, electric vehicle manufacturer Tesla Motors transferred out 1,311.520 ZEV (zero emission vehicle) credits, according to the latest report by the California Air Resources Board (ARB)—by far, the largest of any automaker in the state. The next closest was Toyota, with 507.5 credits; Nissan only transferred 25 credits, and those generated from its PZEVs—not from the LEAF EV.
As of 30 September, Tesla still had a balance of 276.080 credits, according to the data; behind the six major automakers, who are mostly banking their credits.
Researchers develop viable catalysts for reforming of heavy gas oil to hydrogen
October 14, 2013
One approach to delivering hydrogen for the stacks in fuel cell vehicles is via the on-board reforming of hydrocarbon fuels; such an approach obviates the need for on-board hydrogen gas storage technology and leverages the existing liquid fuels infrastructure. However, using more refined low-sulfur hydrocarbon fuels can add to the overall cost of the system. Less refined fuels—such as heavy gas oil—would be less expensive; however, the higher levels of sulfur in the fuels could prove problematic for catalysts.
Now, researchers in S. Korean and Japan have synthesized hollow fiber catalysts networked with perovskite nanoparticles for the production of hydrogen from heavy gas oil reforming, some of which showed high efficiency for H2 production with substantial durability under high concentrations of S, N, and aromatic compounds. Their findings are reported in an open access paper in the journal Scientific Reports.

New family of non-precious metal catalysts outperform platinum for oxygen-reduction reaction in fuel cells at 10% the production cost
September 23, 2013
|ORR polarisation curves of Pt/C and FeCo-OMPC catalysts before and after 10,000 potential cycles in O2-saturated 0.1 M HClO4. Potential cycling was carried out from 0.6 to 1.0 V vs. RHE at 50 mV s−1. Cheon et al. Click to enlarge.|
Researchers from Ulsan National Institute of Science and Technology (UNIST), Korea Institute of Energy Research (KIER), and Brookhaven National Laboratory have discovered a new family of non-precious metal catalysts based on ordered mesoporous porphyrinic carbons (M-OMPC) with high surface areas and tunable pore structures. Porphyrins are any of a class of heterocyclic compounds containing four pyrrole rings arranged in a square.
These catalysts exhibit better performance than platinum in the oxygen-reduction reaction (ORR) important for fuel cells at 10% of the production cost of a platinum catalyst, the team said. The finding, described in an open access paper in Nature’s Scientific Reports, is potentially a step towards reducing the cost of fuel cell technology—one of the impediments to widespread commercialization.
New core-shell bi-layer nanocatalyst tolerant to CO; potential for low-temperature fuel cells with reformates
September 21, 2013
Researchers at Brookhaven National Laboratory have created a high-performing bi-layer durable nanocatalyst that is tolerant to carbon monoxide, a catalyst-poisoning impurity in hydrogen derived from natural gas. The novel core-shell structure—ruthenium coated with platinum—resists damage from carbon monoxide as it drives the energetic reactions central to electric vehicle fuel cells and similar technologies.
The single crystalline Ru cores with well-defined Pt bilayer shells address the issues in using a dissolution-prone metal, such as ruthenium, to alleviate carbon monoxide poisoning, and thereby open the door for commercialization of low-temperature fuel cells that can use inexpensive reformates (H2 with CO impurity) as the fuel, the authors noted. Their paper is published in the journal Nature Communications.

MIT researchers have found a new family of highly active catalyst materials that provides the best performance yet in the oxygen evolution reaction (OER) in electrochemical water-splitting—a key requirement for energy storage and delivery systems such as advanced fuel cells and lithium-air batteries.
The materials, double perovskites (Ln0.5Ba0.5)CoO3−δ (Ln=Pr, Sm, Gd and Ho), are a variant of a mineral that exists in abundance in the Earth’s crust. Their remarkable ability to promote oxygen evolution in a water-splitting reaction is detailed in a paper appearing in the journal Nature Communications. The work was conducted by Dr. Yang Shao-Horn, the Gail E. Kendall Professor of Mechanical Engineering and Materials Science and Engineering; postdoc Alexis Grimaud; and six others.

Researchers from Ulsan National Institute of Science and Technology (UNIST) (S. Korea), Georgia Institute of Technology, and Dong-Eui University (S. Korea) report the development of new efficient and robust cathode materials for low-temperature solid oxide fuel cells (SOFCs) in the open access Scientific Reports.
Conventional solid oxide fuel cells operate as high as 950 °C to run effectively. Test cells based on these new cathode materials demonstrated peak power densities of ~2.2 W cm−2 at 600°C. (The power density of a commercialized low-temperature SOFC system developed by researchers at the University of Maryland and Redox Power is also more than 2W cm-2, earlier post.)

|Redox Power’s 25 kW “Cube” sitting outside a conference room. Click to enlarge.|
University of Maryland researchers have partnered with Redox Power Systems LLC to commercialize low-temperature solid oxide fuel cell (LT-SOFC) technology for distributed generation—and ultimately transportation—applications at about one-tenth the cost and one-tenth the size of current commercial fuel cell systems.
The fuel cells, based upon patented technology developed by professor Eric Wachsman, director of the University of Maryland Energy Research Center (UMERC) in the A. James Clark School of Engineering, are the foundation of a system being commercialized by Redox that provides safe, efficient, reliable, uninterrupted power, on–site and optionally off the grid, at a price competitive with current energy sources.
Bi-metal aerogel catalyst shows promise as high-efficiency, lower-platinum electrocatalyst for fuel cells
August 09, 2013
|Detailed structure of the platinum/palladium aerogel nanowires (alloy ratio: 50% platinum, 50% palladium) Source: PSI. Click to enlarge.|
Researchers from Germany and Switzerland have manufactured and characterized a novel aerogel catalyst that could significantly increase the efficiency and life of low-temperature polymer electrolyte fuel cells as well as reduce material costs by reducing the platinum loading required. A paper on their work appears in the journal Angewandte Chemie.
Using a three-dimensional aerogel made of a platinum-palladium alloy, they were able to increase the catalytic activity for oxygen reduction at the positive electrode of a hydrogen fuel cell five-fold compared to normal catalysts made of platinum on carbon supports—i.e., the same amount of oxygen can now be converted with only a fifth of the amount of precious metals. If this reduction of the necessary platinum load could be transferred onto an industrial scale, it would slash the production costs for these fuel cells.
German-US collaboration demonstrates strong power density results with HEM fuel cell
A German-US collaboration including OH-Energy Germany, GmbH; the University of Delaware; Fraunhofer ICT; and Leibniz Institute for Polymer Research released initial results demonstrating 616 mW/cm2 peak power density at 80 °C for a hydroxide (OH-) exchange membrane (HEM) fuel cell. (Earlier post.)
The results are an early indication the partnership is on track to reach its stated goal of delivering 600 mW/cm2 from a platinum-free fuel cell by 2015. The US Department of Energy (DOE) has a technical target for proton exchange membrane (PEM) MEAs (membrane electrode assembly) of 1,000 mW/cm2 by 2020.
Nitrogen-doped graphene nanoplatelets offer high catalytic performance in fuel cells and solar cells; possible replacement for Pt
July 23, 2013
Researchers in South Korea have developed a simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs) with excellent catalytic performance in both dye-sensitized solar cells and fuel cells to replace conventional platinum (Pt)-based catalysts for energy conversion.
A paper on the work, carried out at Ulsan National Institute of Science and Technology (UNIST), is published in Scientific Reports. The UNIST team had previously reported that dry ball-milling can efficiently produce chemically modified graphene particles in large quantities. This new work dry ball mills graphite with nitrogen gas (N2), resulting in the direct fixation of N2 at the edges of graphene nanoplatelets (GnPs).
Researchers devise Pt electrocatalysts with greatly increased activity; potential for significant cuts in fuel cell cost
July 22, 2013
Researchers in Denmark and Germany have found that size-selected platinum (Pt) nanoclusters can reach extraordinarily high ORR (oxygen reduction reaction—a key reaction in hydrogen fuel cells) activities, especially in terms of mass-normalized activity, if deposited at high coverage on a glassy carbon substrate.
When tested in the laboratory, the mass specific activity of commercial Pt fuel cell catalysts is around 1 A mg-1Pt. The researchers, led by associate professor of chemistry Matthias Arenz at the University of Copenhagen, found one of their catalysts delivered almost 8 A mg-1Pt. Their finding on the role of particle proximity in the efficiency of the Pt ORR activity might enable a significant reduction in the use of platinum in fuel cells for a given power output, resulting in less expensive fuel cells. A paper on their work is published in the journal Nature Materials.

Sandia study finds fuel cell barges may be attractive lower-cost cold-ironing solution for some types of vessels at some ports
June 28, 2013
|Basic concept of a fuel cell barge. Although two containers are shown here, the actual number of containers would depend on the power and energy requirements of the vessel to be powered. Credit: Pratt and Harris (2013). Click to enlarge.|
A study by researchers at Sandia National Laboratories found that hydrogen fuel cell barges may be both technically feasible and commercially attractive as a clean, quiet and efficient power source to provide electrical power for some types of vessels at berth or at anchorage. This practice in which a vessel at berth connects to a source of electricity on the shore is called “cold-ironing”, shore power or Alternative Maritime Power (AMP).
Vessels that are not likely to be technically feasible are cruise ships, refrigerated bulk carriers (reefer vessels), and some types of liquid bulk tankers, according to the study. This, the Sandia team said, is because their multi-megawatt power requirements and potentially long run times would necessitate multiple MW-class fuel cell units and impractically-large stores of hydrogen. Container ships are likely to be feasible, but their power demand depends primarily on the number of refrigerated containers (reefers) on-board.
ACAL Energy FlowCath fuel cell reaches 10,000 hours runtime on automotive durability test; 2x US DOE 2017 target
June 27, 2013
|FlowCath PEM fuel cell. Click to enlarge.|
UK-based ACAL Energy Ltd announced that its FlowCath platinum-free liquid cathode system has enabled a PEM hydrogen fuel cell to reach 10,000 hours’ runtime on a third-party automotive industry durability test without any significant signs of degradation. ACAL Energy’s approach is also significantly cheaper than conventional fuel cell technology. (Earlier post.)
10,000 hours, the equivalent of 300,000 driven miles, is the point at which hydrogen fuel cell endurance is comparable to the best light-weight diesel engines under such test conditions. This endurance far exceeds the proposed US Department of Energy (DoE) industry target for fuel cell powered vehicles to last 5,000 hours, equivalent to 150,000 road miles, with an expected degradation threshold of approximately 10%. (Earlier post.)

R&D will not be funded through this announcement. DOE select up to eight projects from industry, academia, and national labs.
New metal-free ORR catalyst outperforms platinum in fuel cell
June 06, 2013
Researchers from South Korea, Case Western Reserve University and University of North Texas have synthesized new inexpensive and easily produced metal-free catalysts—edge-selectively halogenated graphene nanoplatelets (XGnPs)—that can perform better than platinum in oxygen-reduction reactions. The finding, detailed in an open access paper in Nature’s Scientific Reports, is a step toward eliminating what industry regards as the largest obstacle to large-scale commercialization of fuel cell technology—the high cost and insufficient supply of platinum catalysts.
The XGnPs, which were produced using a simple ball-milling method, were tested as cathode electrodes of fuel cells and revealed “remarkable” electrocatalytic activities for ORR with high tolerance to methanol crossover/CO poisoning effects and longer-term stability than those of the pristine graphite and commercial Pt/C electrocatalysts. In initial tests, a cathode coated with one form of catalyst—graphene nanoparticles edged with iodine—generated 33% more current than a commercial cathode coated with platinum.
New LANL non-precious metal ORR catalyst can out-perform platinum; possible enabler for economical Li-air batteries, fuel cells
June 05, 2013
|ORR polarization plots after 5,000 cycles in O2-saturated electrolyte comparing the new catalyst and a platinum catalyst. Chung et al.Click to enlarge.|
Scientists at Los Alamos National Laboratory (LANL) have designed a new type of nitrogen-doped carbon-nanotube catalyst that shows the highest oxygen reduction reaction (ORR) activity in alkaline media of any non-precious metal catalyst developed to date. When used at a sufficiently high loading, this stable catalyst also outperforms the most active platinum-based catalysts, the team found.
The new catalyst, reported in an open source paper in Nature Communications, could pave the way for reliable, economical metal-air batteries and alkaline fuel cells, providing for practical use of wind- and solar-powered electricity, as well as enhanced hybrid and electric vehicles.

May 27, 2013
|Annual light-duty fuel cell vehicle sales through 2030. Source: Navigant Research. Click to enlarge.|
In a newly published research report (“Fuel Cell Vehicles”), Navigant Research forecasts that worldwide sales of light-duty fuel-cell vehicles (FCVs) will reach the 1,000 mark in 2015 and then begin a period of strong growth, surpassing 2 million vehicles annually by 2030.
The light-duty FCV market will be in a long period of supply constraints until around 2020, the report notes, breaking out only if the infrastructure is in place to meet customers’ fueling requirements. This will require a large investment from government and industry, Navigant concludes. If the infrastructure is built out, automakers will increase their production levels, which will result in major cost reductions—a “virtuous cycle” that will lead to a demand-driven market in the period after 2025.
