The hydrogen fuel cell was once the holy grail that was just around the corner and it was going to make electric cars the future. It was touted much like the miracle battery is just around the corner from today.

Two things killed the hydrogen fuel cell. One, it is a bomb. Two, hydrogen does not appear in nature here on earth, it always has other molecules attached, when you find it. The energy required to split it away from the other atoms is more than the energy derived from it. Thus the doubling of the power generation is required to make it. Why bother, when you can just charge a battery?
