Internal reforming fuel cell system requiring no recirculated cooling and providing a high fuel process gas utilization
This patent describes a system. It comprises: a high temperature fuel cell including: an anode passage comprising an anode electrode, the anode passage being adapted to receive fuel process gas; a cathode passage comprising a cathode electrode. The cathode passage being adapted to receive an oxidant process gas; and electrolyte in communications with the anode and cathode electrodes; catalyst means in the fuel cell for reforming hydrocarbon fuel from a fuel supply to produce fuel process gas including hydrogen for the anode passage. The fuel process gas and the oxidant process gas at the anode and cathode electrodes in the presence of the electrolyte undergoing electrochemical conversion to produce electrical energy and the reforming of the hydrocarbon fuel being such as to absorb heat produced by the electrochemical conversion in an amount to maintain the temperature of the fuel cell substantially at a preselected temperature; a means for receiving the gas exhausted from the anode passage and utilizing the fuel process gas in the exhausted gas.
