摘要： The present invention concerns a method for producing a membrane-electrode assembly (MEA) 2, as well as a MEA 2 produced according to this method. This MEA 2 comprises an ion exchange membrane 2a such as a proton-exchange membrane (PEM), a first gas diffusion layer (GDL) 2c on a first side of the ion exchange membrane 2a, and a sealing frame 2d around the first GDL 2c. The method comprises jetting a resin 8 as droplets 9 onto the first side of the ion exchange membrane 2a to cover a gap 7 between the first GDL 2c and the sealing frame 2d and curing the resin 8 covering the gap 7. The membrane-electrode assembly 2 produced according to this method may be used in a fuel cell 1, in particular for a fuel cell electric vehicle (FCEV).

摘要： An object of the present disclosure is to provide a method for manufacturing a fuel cell that ensures developing a high adhesive strength to a separator. One aspect of an embodiment is a method for manufacturing a fuel cell where a pair of separators are mutually bonded with a sealing member. The sealing member includes a thermoplastic resin containing a crystalline polymer as an adhesive layer. The method for manufacturing the fuel cell includes: preparing a stack structure in which the sealing member is disposed between the pair of separators; heating the stack structure at a melting point or higher of the thermoplastic resin; after the heating, holding the stack structure in a temperature range of ±10°C of a crystallization temperature of the thermoplastic resin to promote a crystallization of the thermoplastic resin; and after the holding, further cooling the stack structure.
