One of the most promising alternatives is hydrogen fuel cells, which use hydrogen to directly generate electricity via a reaction with oxygen, but the race is still very open as to which hydrogen ...

With [Lloyd]’s project for The Hackaday Prize, a low cost hydrogen fuel cell. Traditionally, fuel cells have required expensive platinum electrodes to turn hydrogen and oxygen into steam and ...

[Source: Fuel Cell Insider, Popular Mechanics] As I said, only newer engines equipped with knock sensors will be able to automatically compensate for the knocking that can generated by hydrogen ...

Hydrogen fuel cells, by contrast, don’t burn liquid hydrogen, but create electricity from it by a completely different method. Rather than using a combustion engine, hydrogen fuel cell vehicles ...
