PROTON CONDUCTOR FOR FUEL CELL, ELECTRODE FOR FUEL CELL, AND FUEL CELL USING THE SAME

摘要

PURPOSE: A proton conductor for a fuel cell, an electrode including thereof, and the fuel cell using thereof are provided to improve the oxygen solubility of a phosphonic acid material using perfluoroalkyl sulfonate ammonium salt, and to improve the utility ratio of a Pt catalyst. CONSTITUTION: A proton conductor for a fuel cell contains a phosphonic acid material, and perfluoroalkyl sulfonate ammonium salt with C1~C20 capable of being dissolved into the phosphonic acid material. The phosphonic acid material is either phosphoric acid or organic phosphonic acid with C1~C20. The fuel cell using the proton conductor includes a cathode, an anode, and an electrolyte film located in between the cathode and the anode. At least one of the cathode and the anode contains the proton conductor.
