Fuel cells are being developed and implemented for applications ranging from stationary power generation, primary and auxilary power in automobiles and trucks to battery replacements in consumer electronics. In all cases the fuel cell operates on hydrogen, but the primary fuel can vary from natural gas to liquid hydrocarbons to bio-fuels. To reform these fuels either steam or air or both are used, but the processing detail can be challenging. Mixing the fuel and oxidant is difficult for the heavier fuels, avoiding carbon formation is always an issue, and dealing with sulfur is also. The issues will be discussed in some detail as will be some novel catalysts.
