SAE World Congress: Honda FCEV fuel cell stack has cells just 1 mm thin

The only update we have for people who are paying ultra-close attention to the progress of the hydrogen-powered Honda FCEV concept is that we now know how thin the individual cells in the car's fuel cell stack are. Speaking at the 2015 SAE World Congress in Detroit this week, American Honda Motor Company Manager of fuel cell vehicle marketing, Steve Ellis, told AutoblogGreen that the fuel cell stack is now 33-percent smaller and offers a 60-percent improvement in power density. We knew this already. What we didn't know is how Honda got there. Ellis said that these improvements are due in part to a reduction in the size of the fuel cell thickness. Each cell in the stack is one millimeter thick, he said.

For everyone who isn't counting the millimeters of this car, here's the broader situation. Honda and the state of California (and others) are working hard on getting H2 infrastructure up can running. "The stations are accelerating as we speak," Ellis said. Three new stations have opened in the last few months and the state has pledged $20 million per year until there are 100 stations in California. Honda has also invested in FirstElement to install stations.

The production FCEV will feature a range of over 300 miles and have a three-to-five minute refueling time. The car will launch in Japan in March 2016, with US and European sales starting at some unspecified time after that.
