The problem with hydrogen is that it is not a very portable fuel.

Lots and lots of things are happening that indicate a worldwide interest, and most of the knowledgeable people are convinced that the next-generation replacement for the internal combustion engine is going to be a fuel...

We really and truly expect that fuel cells are going to double the fuel efficiency of the best internal combustion engines and in some cases triple it.

If you turn the experiment around and put the hydrogen and oxygen in and take the electricity off, you have a fuel cell.
