In 1839, Briton Sir William Robert Grove discovered that hydrogen and oxygen could be combined to produce water and an electric current. In the late 1950s, Francis Bacon's research team developed a more advanced fuel cell. This design was used for NASA's Apollo moon missions and Skylab programs.

Today, fuel cell technology is being brought back to earth to power everything from cars and buses, to homes and businesses, and even cellular phones and laptop computers.
