In a fuel cell the hydrogen isnÆt really burned. ItÆs just aloud to recombine with oxygen. So producing water. One really cool thing I heard recently is that Iceland has started a project thatÆs goal is to produce fuel cell vehicles and residential fuel cells with hydrogen pumping station all over Iceland. Since Iceland has an unlimited source of ac power in the way of stem powered generators because of the abundance of volcanic activity. They can produce oxygen and hydrogen through a process called ôelectrolysisö. Thus the expense of creating hydrogen is almost completely eliminated. And the cost of running a fuel cell is greatly reduced. But you still have the problem of having a tank of hydrogen in you rig. Not something I would want to carry around.
