Document Type and Number:

Japanese Patent JP4979179

Kind Code:

B2

Abstract:

To improve oxidation resistance of an electrolyte membrane and durability thereof by a low-cost method, thereby improving durability of a polymer electrolyte fuel cell. According to the present invention, in the polymer electrolyte fuel cell having a membrane-electrode assembly including a polymer electrolyte membrane and electrodes bonded to both sides of the polymer electrolyte membrane, phosphate containing at least one metallic element selected from a rare earth element, Ti, Fe, Al and Bi is fixed to at least one of the polymer electrolyte membrane and the electrodes.
