ELECTRODE CATALYST FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide an electrode catalyst used in manufacturing fuel cells. SOLUTION: The electrode catalyst contains carbon black having a larger H content than 4000 ppm as a carbon carrier and platinum as a catalyst activating component or a platinum doped with two or more sorts of metal or turned into an alloy and is manufactured by precipitating noble metal(s) on the surface of the carbon black.
