Electrode catalyst for fuel cell, method for producing the electrode catalyst, and polymer electrolyte fuel cell using the electrode catalyst
Abstract:
An electrode catalyst for a fuel cell, which has improved performance compared with conventional platinum alloy catalysts, a method for producing the electrode catalyst, and a polymer electrolyte fuel cell using the electrode catalyst are provided. The electrode catalyst for a fuel cell comprises a noble-metal-non-precious metal alloy that has a core-shell structure supported on a conductive carrier. The composition of the catalyst components of the shell is such that the amount of the noble metal is greater than or equal to the amount of the non-precious metal.
