Hydrogen Power from PEM Fuel Cells

Proton exchange membrane fuel cells use hydrogen gas to make electric current. They are part of the search for cleaner energy sources that can help replace non-renewable fuels used for electricity, transportation, industry, and homes. The United States now uses about 97.5 quadrillion BTUs of energy each year, and about 90% s...
