  • Membrane electrode assembly and method of producing the same and fuel cell
    Patent number: 8278004
    Abstract: It is an object of the present invention to provide a method of producing a membrane electrode assembly using an interface resistance reducing composition which can simply reduce the resistance of the interface between an electrode and an electrolyte membrane in a short time at low temperatures at low pressure without polymerization while maintaining an effect of suppressing a fuel crossover even with an electrolyte membrane having high heat resistance, high strength, a high tensile elastic modulus and a low water content.
    Type: Grant
    Filed: July 9, 2010
    Date of Patent: October 2, 2012
    Assignee: Toray Industries, Inc.
    Inventors: Shinya Adachi, Daisuke Izuhara, Masataka Nakamura, Naoki Shimoyama, Takao Uete, Masayuki Kidai

  • Membrane electrode complex and solid type fuel cell using it
    Patent number: 7824786
    Abstract: A polymer electrolytic material has excellent proton conductivity and excellent fuel shutting property, and accordingly provide a polymer electrolytic fuel cell with a high efficiency. This polymer electrolytic material has an unfreezable water ratio Rw1 defined by the following expression (S1) in a range of 20 to 100% by weight in hydrated state: Rw1=[Wnf/(Wfc+Wnf)]×100??(S1) in which Wnf represents the unfreezable water content per 1 g of the polymer electrolytic material in dry state and Wfc represents the low freezing point water content per 1 g of the polymer electrolytic material in dry state.
