  • Reinforced electrolyte membrane for fuel cell, production method thereof, membrane electrode assembly for fuel cell, and solid polymer fuel cell comprising the same
    Patent number: 8114550
    Abstract: A reinforced electrolyte membrane for a fuel cell which is reinforced by a porous membrane, characterized by containing void portions in a joining portion between the surface of the porous membrane and/or pore surface and the electrolyte for buffering swelling when water is contained. This reinforced electrolyte membrane for a fuel cell has improved dimensional stability even if the electrolyte swells.
    Type: Grant

  • REINFORCED ELECTROLYTE MEMBRANE COMPRISING CATALYST FOR PREVENTING REACTANT CROSSOVER AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20090039540
    Abstract: An object of the present invention is to reduce the amount of hydrogen gas permeating an electrolyte membrane to inhibit cross leak, in which hydrogen reacts with oxygen to thermally degrade the membrane, while improving the mechanical strength of the fuel cell to increase its durability and lifetime. The present invention provides a fuel cell reinforcing electrolyte membrane reinforced by a porous membrane, wherein noble metal carrying carbon is present on a surface of and/or in pores in the porous membrane, said membrane being covered by electrolyte layers.
