  • Patent number: 8338059
    Abstract: The present invention provides a membrane-electrode assembly comprising: electrodes consisting of a anode comprising a gas diffusion layer and a catalyst material-containing active layer, and an cathode comprising a diffusion layer and a catalyst material-containing active layer; and an electrolyte membrane interposed between the anode and the cathode and comprising a catalyst material-containing active layer at one or both sides, the electrodes being hot-pressed, to the electrolyte membrane, wherein in coating the active layer on the gas diffusion layer, the viscosity of the active layer is in a range of 100 to 10,000 cPs, as well as a production method thereof. The inventive membrane-electrode assembly has a low interfacial resistance between the membrane and the electrodes, as well as high catalyst availability and excellent power density, and can be mass-produced.

  • Patent number: 7544219
    Abstract: The present invention relates to a gasketed membrane-electrode assembly comprising gaskets arranged on each side of a membrane-electrode assembly including a cathode, an anode, and a polymer electrolyte membrane, in which the gaskets are multilayered films comprising an elastic layer and an adhesive layer formed on each side of a support layer. According to the present invention, the gasket film can be united with the polymer electrolyte membrane, and the leakage of fuel gas and oxidizing gas decreases on operation of a fuel cell. In addition, various materials can be selected for each layer of the gasket. Thus, it can be suitable for mass production of a polymer fuel cell due to its simple manufacturing process.
