Abstract:
A fuel cell power supply for producing electricity from fuel and oxidizer reactants, comprisinga cell stack assembly including at least one fuel cell having an anode, a cathode, and a solid electrolytic medium therebetween, said cell stack assembly adapted for defining a solid anode flow field for receiving a fuel for exposing said anode thereto, for providing an exhaust to said anode flow field, and for defining a cathode flow field for receiving and exposing said cathode to an oxidizer;water removal means for removing water from said cathode flow field; anda combustion unit for receiving exhaust from the anode flow field to produce a combusted exhaust including water, said combustion unit in fluid communication with at least one of said anode flow field and said cathode flow field for providing at least a portion of said combusted exhaust to said at least one of said cathode flow field and said anode flow field.
