Mysteries of the Fuel Cell explained

Carjunky has a somewhat strangely worded article up on how a hydrogen fuel cell turns hydrogen into heat and water while powering a motor. If you’re unsure about this new hydrogen economy that we’re always getting promised, perhaps the details in this piece may help you understand at least the general idea that hydrogen is fed into a porous anode and a catalyst separates the electrons and ions in the hydrogen. The electrons combine with oxygen, producing water and, depending on the fuel cell, heat or electrons. At least that’s how I read it. Like I said, it’s slightly strangely worded. I think Wikipedia’s detailed explanation is more suited to understanding fuel cells.
