Richard, ALL fuel cells use hydrogen exclusively to generate electricity. A hydrogen atom consists of a proton and an electron. In a proton exchange membrane (PEM) fuel cell, the proton passes through the membrane to unite with oxygen while the electron follows a circuit around the membrane. This produces electricity. A reformer, a miniature refinery that strips carbon, sulfur, nitrogen, etc. away from petroleum or natural gas products, can be added to a fuel cell. This combination will result in a fuel cell vehicle that runs on gas, diesel, NG, etc. but the stripped elements must be disposed of. A variation of the PEM fuel cell takes in a mixture of methanol (CH4)and water (as a transport medium) and strips the hydrogen away from the carbon. Direct Methanol Fuel Cells (DMFCs)have had a tendency to "poison" the membrane with carbon but recent research looks promising. The different types of fuel cells are explained in detail on the California Hydrogen Business Council web. Choose "Fuel Cells" from the menu. Honda has closed the book on battery-powered electrics to develop fuel cell vehicles. -- Rickmas
