Fuel Cell Cars; September 2008; Scientific American Earth 3.0; by James R. Healey; 2 Page(s)

Amid many promises about futuristic automobiles, an unlikely one seems to be coming true: hydrogen fuel-cell cars.

No, you can¿t buy a hydrogen car from a local dealer. But General Motors (GM) and American Honda Motor are putting close to 300 street-legal, fullfeatured, hydrogen fuel-cell machines into the hands of individual American drivers for use in real-world conditions. Long-term, a fleet could help reduce dependence on oil and lessen greenhouse gas emissions because the cells produce no pollution, just water.
