Honda FCX concept fuel cell car in depth, Pt. 1 - The new fuel cell stack
Filed under: Hydrogen, Honda, AutoblogGreen Exclusive

In June of 2005 Honda became the first car company in the world to lease a hydrogen fuel cell powered car to Jon Spallino, of Redondo Beach, California. During the 2005-6 auto show season, they showed off a concept version of their first purpose-built fuel cell powered car. Earlier this year they announced that the car would go into low volume production in 2008 and yesterday they allowed a group of journalists to drive the first two prototypes at the Laguna Seca racetrack along with the two of the current generation FCX cars. I was there.
The day began with a technical presentation of where Honda's fuel cell development has been and where it's going. Unlike most other car-makers working on hydrogen power, Honda is designing and building their own fuel cell stacks. The previous generations of stacks have been laid out much like the ones from companies like Ballard where the gases flow horizontally through the stack. This horizontal flow is what has led to one of the problems with fuel cells in cars, cold weather performance.
