Abstract
Provided is an electrode catalyst material that has an increased reduction rate of a nickel catalyst and thus an improved catalytic function in a fuel cell. The electrode catalyst material for fuel cells contains nickel oxide and cobalt oxide. The electrode catalyst material contains a cobalt metal component in an amount of 2 to 15 mass % with respect to the total mass of a nickel metal component and the cobalt metal component.
