  • CATALYST FOR FUEL CELLS
    Publication number: 20090042079
    Abstract: To provide a catalyst for a fuel cell that has a high oxygen reduction activity and is manufactured at low cost and a fuel cell that has a high power generation efficiency and is manufactured at low cost. As a catalyst for a fuel cell that reduces an oxidizing gas, a catalyst for a fuel cell that contains palladium at least partially oxidized is used. In a fuel cell having an anode that oxidizes a fuel, a cathode that reduces an oxidizing gas and a solid polymer electrolyte membrane disposed between the anode and the cathode, a palladium oxide is used as a cathode catalyst.
