  • ELECTRODE FOR FUEL CELL, METHOD OF PREPARING THE SAME, MEMBRANE ELECTRODE ASSEMBLY AND FUEL CELL INCLUDING THE SAME
    Publication number: 20110281199
    Abstract: An electrode for a fuel cell with an operating temperature of about 100° C. or more. The electrode has an electrode catalyst layer that includes an electrode catalyst with a conductive carrier and catalyst particles supported on the conductive carrier. The electrode catalyst includes an acid impregnated electrode catalyst in which the conductive carrier is impregnated with an acid component having proton conductivity by a heat treatment with the acid component in advance, and a non-impregnated electrode catalyst. The acid impregnated electrode catalyst and the non-impregnated electrode catalyst are uniformly distributed in the electrode catalyst layer.
