A fuel cell is a device that converts fuel directly into electricity, a process far more efficient than indirect methods of energy conversion, such as heating steam to turn a turbine connected to an electrical generator.

In 1966, automobile manufacturer GM created its first fuel cell-powered automobile. Did it work?
