The first fuel cell car was developed by which company, when?
Surprise answer: General Motors, in 1966. (Sound of jaws dropping in the audience, no doubt...)
The Electrovan looked like a GMC van on the outside, but inside it looked like Mad Scientist City. Developed by Craig Marks and associates, the Electrovan had a Union Carbide fuel cell that used liquid hydrogen and liquid oxygen. Yes, it was rocket science. Hydrogen fuel cells need oxygen, which, while amply available here on Earth, is a "bring your own" commodity in space. Fuel cells, at that time, were space-capsule technology.
I saw the Electrovan in person when the California Fuel Cell Partnership hydrogen-refueling station in West Sacramento, Calif., was opened back in 2000. It was a static display, and a fascinating piece of history. Think Leonardo da Vinci's helicopter, only actually built. Well, maybe not quite that futuristic, but close.
