摘要： The membrane electrode assembly 100 has an electrolyte layer 10, a catalyst layer 20, and a member 15 impregnated with electrolyte which is arranged between the electrolyte layer 10 and the catalyst layer 20. At least part of the peripheral edge portion of the member 15 extends the outside the peripheral edge portions of the electrolyte layer and the catalyst layer 20. With this kind of constitution, it is possible to easily separate the electrolyte layer 10 or the catalyst layer 20 from the member 15 from the extended portion of the member 15. Consequently, it is possible to easily replace the electrolyte layer 10 and the catalyst layer 20.

摘要： A fuel cell is formed by alternately stacking separators and sealing gasket-combined membrane electrode assemblies. Each sealing gasket-combined membrane electrode assembly includes a membrane electrode assembly and a sealing gasket portion. One of the sealing gasket portion and the separator has a protrusion formed on each face and extending in a stacked direction in which the separators and the sealing gasket-combined membrane electrode assemblies are stacked. The other of the sealing gasket portion and the separator has a recess in which the protrusion is fitted. The protrusions formed respectively on opposed faces of the successive sealing gasket-combined membrane electrode assemblies or the successive separators are located at different positions.

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.
