Abstract:
A direct oxidation fuel cell system comprising:(A) a direct oxidation fuel cell including an anode, a cathode, and a protonically conductive, electronically non-conductive membrane electrolyte disposed between the anode and the cathode; (B) a source of oxygen coupled to said cathode so as to produce electricity-generating reactions including anodic disassociation of a fuel and water mixture to produce carbon dioxide, protons and electrons and a cathodic combination of protons, electrons and oxygen producing water; (C) a source of fuel; (D) a gas separator coupled to receive said carbon dioxide produced at said anode; and (E) a turbine assembly coupled between said gas separator and said cathode in such a manner that carbon dioxide causes operation of said turbine assembly to in turn draw air across said cathode.
