Honda demonstrates fuel cell concept vehicle

Tochigi, Japan – Honda Motor Company has held a demonstration drive of its next-generation FCX Concept fuel cell vehicle, which features a newly-developed, compact, high-efficiency fuel cell stack in a low-floor vehicle. Limited marketing of a totally new fuel cell vehicle based on the concept is to begin in Japan and the U.S. in 2008.

The FCX’s new fuel cell stack is 20 per cent smaller and 30 per cent lighter than the current FCX stack, yet its power output is 14 kW greater. Overall, the new FCX powerplant is about 180 kg lighter than that of the current FCX, and about 40 per cent smaller in volume, for improved energy efficiency and performance with a more spacious interior.

While Honda’s previous fuel cell stacks flowed horizontally, the new stack features vertical-flow design, which allows gravity to assist in discharging the water that is produced. This results in a major improvement in water drainage, which is key to high-efficiency fuel stack performance. Low-temperature startup has also been significantly improved, to as low as minus 30C.
