The current administration in Washington clearly doesn't favor the pursuit of hydrogen fuel cells, but that doesn't mean General Motors is giving up on the technology. In spite of the pending retirement of Larry Burns, VP of research and development, his replacement, Alan Taub, remains committed to bringing fuel cells to production. GM's fifth generation fuel cell stack is comparable in size to a 2.4-liter EcoTec four cylinder and far less expensive to manufacture than past iterations of the fuel cell stack.
There is still work to do, since the latest fuel cell system is about 30 percent more expensive than the Volt powertrain. Taub said GM still hopes to start series production of fuel cells by about 2012. GM is by no means alone in these efforts as Daimler, Toyota, Honda, and Hyundai have all remained publicly committed to fuel cells. The big problem still remains hydrogen distribution.
