摘要： According to a manufacturing method for a fuel cell, an insulating member having a plurality of communication holes therein is 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, an electric current flows through a protrusion portion of a carbon fiber which comes in contact with the electrode on the water-repellent layer side via the communication holes of the insulating member, so that the protrusion portion of the carbon fiber is burned and removed by Joule heat. When it is detected that no electric current flows between the electrodes, application of a voltage to the pair of electrodes is stopped, and the pressure in the pressurized state is decreased to a normal pressure state.
摘要翻译：根据燃料电池的制造方法，具有多个连通孔的绝缘部件设置在通过层叠由碳纤维和拒水层构成的层而形成的气体扩散层的一侧，在其中设置防水层的情况下，气体扩散层和绝缘构件被一对电极夹持，并且一对接触压力板设置在该对电极的各个后表面上，以夹持该对电极电极，使得气体扩散层被一对接触压力板加压。当在保持加压状态的同时对一对电极施加电压时，电流通过绝缘构件的连通孔流过与斥水层侧的电极接触的碳纤维的突出部分，使得碳纤维的突出部分通过焦耳热被燃烧和去除。当检测到电极之间没有电流流动时，停止向一对电极施加电压，并且加压状态下的压力降低到正常压力状态。
