A fuel cell power system is provided that includes a fuel cell for generating electricity that has a cathode, an anode, and a polymer electrolyte membrane. The fuel cell processes air through the cathode to yield a cathode effluent stream. The fuel cell power system further includes a fuel processor
A fuel cell power system is provided that includes a fuel cell for generating electricity that has a cathode, an anode, and a polymer electrolyte membrane. The fuel cell processes air through the cathode to yield a cathode effluent stream. The fuel cell power system further includes a fuel processor for converting an inlet fuel stream of hydrogen and carbon containing fuels, utilizing a stream of oxygen containing gas and water vapor, to a processed fuel stream of hydrogen molecules for feeding into the fuel cell anode. The system then feeds a substantial portion of the cathode effluent stream to the fuel processor as the oxygen containing gas and water vapor for converting the fuel stream into hydrogen. A method of using the system is also provided.
