Intelligent Energy claims highest power densities yet for automotive fuel cells

UK-based Intelligent Energy announced that its proprietary fuel cell technology is providing leading levels of power output and performance for a number of its automotive customers, with the company’s fuel cell stacks demonstrating continuous volumetric and gravimetric power densities of 3.7 kW/L and 2.5 kW/kg, respectively.

We believe that our fuel cell stack technology has achieved industry leading power density performance. These interim results are only part way along our technology roadmap and much more is still to come with further improvements in the pipeline.

Importantly, we deliver these benchmark performance levels using our own patented technology which has been designed for high volume, low-cost manufacturing. We provide our technology to existing clients as they progress towards series production and continue to work with new automotive customers and OEMs under a variety of commercial arrangements.

—James Batchelor, Intelligent Energy’s Motive Division Managing Director

In 2012, the company formed a joint venture in Japan with the Suzuki Motor Corporation to manufacture fuel cells for a range of automotive and other sectors. (Earlier post.) In February of this year, within 12 months of its incorporation, the joint venture, SMILE FC System, announced the completion of the first ready-to-scale production line. (Earlier post.)



Actual fuel cell price and longevity is never stated.


When you look at the report, it is 180 vehicles that each put on about 15,000 miles over a 5 year period. That is not exactly a rigorous test.

I think that they will get the longevity up to acceptable levels, the cost is another matter entirely. If you use platinum, it costs. When you have a thousand cell plates, it costs. Then there is the fueling..maybe a bridge too far right now.


Well don't forget sjc various fuel cell companies are at VERY different staged of dev. We have no idea what stage these guys realy are at they could be 3 years from product or 15...

Some of the companies will be weeded out when the first ones hit market in the next few years and the ones that are too far behind loose investment funding and poof/get eaten.

As for platinum... that's another issue.. some current fuel cell designs use a lot more plat then others... But even the most platinum hungry designs I know of still wouldn't result in much more then 10-15k worth of platinum in a stack.. and those arnt likely to survive the first few years when fuel cells hit market.

The better ones should be under 1 grand of plat maybe even well under by 2015-2018 timeframe. That's I think 9 grams of platinum as I remember my prices...
