CATHODE ELECTRODE FOR FUEL CELL

A cathode electrode for a fuel cell, includes a conductive carrier having pores and a catalyst having a platinum alloy supported in the pores of the conductive carrier, wherein the catalyst has in a pore diameter range of 2 to 6 nm when diameters of the pores is plotted in relation with volumes of the pores a peak value of more than 1 cm/g and also a BET specific surface area of 1300 m/g.
