A FUEL CELL USING A CATALYTIC COMBUSTOR TO EXCHANGE HEAT

摘要

A fuel cell preferably includes a fuel cell stack for receiving reactants a nd conducting a reaction to produce an electrical current, a catalytic combusto r for combusting reactants that pass un-reacted through the fuel cell stack, and a heat exchanger for exchanging heat from an exhaust of the catalytic combustor to the reactants received by the fuel cell stack.
