  • Patent number: 9608277
    Abstract: A method for manufacturing an alloy catalyst for a fuel cell is disclosed. The method for manufacturing an alloy catalyst for a fuel cell may include predetermined processes and reaction conditions, such that iridium is alloyed to platinum contained in a cathode carbon support catalyst. Accordingly, time for stabilizing charge on the carbon surface may be reduced and a metal particle size may be controlled, thereby manufacturing high quality products having uniform metal particle distribution and improved durability. In addition, corrosion of a cathode carbon support catalyst in a harsh condition such as vehicle driving may be prevented.

  • Patent number: 9570758
    Abstract: A method of manufacturing a fuel cell. An insulating member has a plurality of communication holes disposed on a side of a gas diffusion layer, which is formed by stacking a layer made of a carbon fiber and a water-repellent layer, where the water-repellent layer is provided. The gas diffusion layer and the insulating member are sandwiched by a pair of electrodes, and a pair of contact pressure plates are disposed on respective rear surfaces of the pair of electrodes so as to sandwich the pair of electrodes so that the gas diffusion layer is pressurized by the pair of contact pressure plates. When a voltage is applied to the pair of electrodes while maintaining the pressurized state, the protrusion portion of the carbon fiber is burned and removed by Joule heat.

  • Patent number: 9466851
    Abstract: This fuel-cell gas diffusion layer includes a conductive porous layer constituted by: porous carbon formed so as to have a porosity distribution substantially uniform in a stacking direction with respect to a membrane electrode assembly; and a PTFE resin arranged dispersedly across the inside of the carbon. When a ratio of a surface of the carbon to a surface that is exposed without being covered with the PTFE resin is defined as an exposure ratio, the exposure ratio of a surface, on a cathode electrode side, of the conductive porous layer, is higher than the exposure ratio, on a diffusion-layer base material side, of the conductive porous layer.

  • Patent number: 9425465
    Abstract: The production method according to the present invention includes a process for producing fine particles formed of a non-precious metal; a process for forming a shell of a precious metal on the respective surfaces of the fine particles of the non-precious metal; and a process for collecting a catalyst from a fluid reaction mixture. A fine metal particle-carrying catalyst prepared by such a production method includes fine non-precious metal particles as the cores thereby reducing the usage of a precious metal to achieve suppression of a cost increase. Since it includes a shell portion formed of a precious metal, it exhibits excellent catalytic activity.

  • Patent number: 9379388
    Abstract: A method for making a carbon-metal-nitrogen oxygen reducing cathode catalyst, the method comprising mixing a carbon source with a transition metal precursor to form a metal precursor loaded carbon substrate; adding a nitrogen precursor compound to the metal precursor loaded carbon substrate to form a carbon-metal-nitrogen precursor; and pyrolyzing the carbon-metal-nitrogen precursor in a closed vessel, thereby forming an oxygen reducing cathode catalyst. The carbon-metal-nitrogen catalyst requires no precious metal such as Pt, and also provides benefits such as controlled deposition of catalytically active nitrogenous compounds that can increase the catalytic activity of the catalyst when compared to gaseous deposition of nitrogen to the surface of the carbon support.
