The main energy sources of today are slowly running out, and many of them have high levels of pollution. In the future, an alternate source of energy will be needed, and a cleaner way to produce the energy. One possibility for an alternate energy source would be Fuel Cells. Fuel cells have been around for much longer than most people realize. Fuel cells have been known to science for around the past 150 years. In 1838, William Robert Grove had an improved wet-cell battery, known as the ‘Grove Cell’. His wet-cell battery used the concept used today for fuel cells. In 1939, Francis Thomas Bacon created an alkali electrolyte fuel cell that was reliable enough to be used in 1958 as the Apollo spacecraft’s fuel cells. However, a truly workable fuel cell was not demonstrated until 1959. After fuel cell use in NASA spacecraft, interest in fuel cells died down until the 1990’s, when research and development in fuel cells started up again in full force. The fuel cell has competition in energy conversion, but has advantages over standard internal combustion engines, which produce pollution when the gasoline is burned, and only has an efficiency rating of 20%. This means that only 20% of the energy stored in gasoline is being us
