ELECTRODE CATALYST FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a new electrode catalyst for fuel cell, which can decrease the used amount of platinum high in activity for an oxygen reduction reaction and high in cost.

SOLUTION: The electrode catalyst for fuel cell contains one or more molybdenum oxides in which an atomic ratio O/Mo of oxygen O to molybdenum Mo is 24O11+α, Mo17O47+α, Mo5O14+α, Mo8O23+α, Mo26O75+α, Mo9O26+α, Mo19O55+α, and Mo13O38+α, where α are -0.01≤α≤0.01 respectively.
