SOLID POLYMER FUEL CELL AND ITS DAMAGE PREVENTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell and its damage preventing method capable of stopping or suppressing the reaction when water decomposition reaction caused by insufficient fuel arises or oxygen is generated in an anode to prevent the damage of a cell. SOLUTION: In the solid polymer fuel cell having a cathode electrode as a reaction layer on one side of a solid polymer electrolyte membrane and an anode electrode as a reaction layer on the other side of the solid polymer electrolyte membrane, tin oxide is included in a catalyst carrier material of the anode electrode.
