GM, Honda to unite on fuel-cell vehicles

General Motors Co. and Honda Motor Co. are joining forces to develop hydrogen fuel-cell vehicles.

The two companies said on Tuesday they plan to develop hydrogen storage and fuel-cell technologies by 2020.

Fuel-cell vehicles have electric motors that are powered by a chemical reaction between hydrogen and oxygen. The only byproducts are water vapor and heat, so there's no pollution. But the lack of infrastructure to transport and store liquid hydrogen has been a barrier to the cars' development.

GM and Honda have more than 1,200 fuel-cell patents between them, and both companies have experimental vehicle fleets.
