The fuel cell is an electrochemical device which converts the chemical energy of various fuels into electricity. Experiments with fuel cell type devices dates back to the early 19th century. The internal construction of various fuel cells differ, some use a permeable membrane to separate the polarized electrodes, whereas some have a cylindrical geometry and employ a solid state construction. The latter type convert the fuel into electrical energy very efficiently and have the best environmental performance of any power producing device.
Fuel cells can operate on a variety of gaseous and liquid fuels.
Fuel cells have been used in our Nations' space program from the very beginning. Industry experts agree that for a fuel cell to become commercially viable, they must reliably operate for a minimum of five years and be able to withstand many thermal cycles over their useful lives. Fuel cells must also be cost effective and competitive with other types of electric power generation equipment.
