  • 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.
