"What are Fuel Cells?"

A fuel cell is a new power generation system that produces electricity from hydrogen and oxygen. Fuel cells are clean and energy-efficient. In space shuttles, fuel cells provide electricity for experiments and life aboard the shuttle, as well as producing drinking water. Now, research and development is underway to commercialize fuel cell cars, residential fuel cells, and various other products and applications. The movie shows how fuel cells produce electricity and how they benefit us.
