The Energy Department’s National Renewable Energy Laboratory (NREL) and General Motors (GM) are partnering on a multi-year, multi-million dollar joint effort to accelerate the reduction of automotive fuel cell stack costs through fuel cell material and manufacturing research and development (R&D). Most major automakers, including GM, have made significant progress in the development of fuel cell electric vehicles, but achieving commercial deployment with global impact will require further cost reductions.
NREL and GM will focus on critical next-generation fuel cell electric vehicle challenges, which include reducing platinum loading, achieving high power densities, understanding the implication of contaminants on fuel cell performance and durability, and accelerating manufacturing processes to achieve the benefits of increased economies of scale.
The work will be done under a Cooperative Research and Development Agreement (CRADA) between NREL and GM and takes advantage of NREL’s state-of-the-art Energy Systems Integration Facility (ESIF). The effort includes staff collaboration and the exchange of equipment, knowledge, and materials.
Special features of the facility include hazardous material and gas handling capabilities and the infrastructure required to support a wide range of appropriate test conditions including integrated electrical, thermal, and hydrogen systems.
In July 2013, GM and Honda announced a long-term collaboration to co-develop next-generation fuel cell and hydrogen storage systems, aiming for potential commercialization in 2020. In addition, GM and Honda are working together with stakeholders to further advance refueling infrastructure, which is critical for the long-term viability and consumer acceptance of fuel cell vehicles.

Also, last year, GM opened a new state-of-the-art Fuel Cell Development Laboratory at GM Powertrain World Headquarters in Pontiac, Michigan. According to The Clean Energy Patent Growth Index, GM ranked No. 1 in total fuel cell patents granted in 2013, and continues to lead all companies in total fuel cell patents granted since 2002.
NREL’s work on the project is funded by the Energy Department’s Fuel Cell Technologies Office in the Office of Energy Efficiency and Renewable Energy.
NREL’s collaboration with GM dates back to 1993, when the Partnership for a New Generation of Vehicles was launched to accelerate development of hybrid-electric cars. Since then, the automaker has been one of the lab’s key partners in advancing sustainable transportation R&D, with projects ranging from advanced power electronics and battery thermal management and modeling studies to a multiyear National Fuel Cell Electric Vehicle Learning Demonstration. Data from the Learning Demonstration were sent to the National Fuel Cell Technology Evaluation Center (NFCTEC), a data center housed within ESIF for independent analyses of advanced hydrogen and fuel cell technologies. This latest effort builds on a team project studying the effects of system contaminants on fuel cells that NREL and GM have been part of since 2009.
