    摘要: Molten carbonate fuel cells are operated with a cathode inlet stream that contains a portion of a combustible gas which may be a hydrocarbon, hydrogen, or other gas that will combine with oxygen to form heat on the cathode catalyst surface. The combustible gases can be reacted in the cathode and/or in a stage that is heat integrated with the cathode. The heat generated by the combustion reaction in the cathode can be used, for example, to allow additional endothermic reactions (such as reforming) to take place in the anode portion of the fuel cell while still maintaining a desirable temperature gradient across the fuel cell. Optionally, the cathode of the fuel cell can be modified to further enhance or control the combustion within the cathode, such as by introducing an additional catalytic surface in the cathode.
