Zusammenfassung:A method for fabricating a fuel cell includes fixedly attaching a reinforcement to a proton-exchange membrane and to an electrode placed against a first face of the proton-exchange membrane. The reinforcement has a median aperture through which an interior portion of the electrode is exposed. Fixedly attaching the reinforcement includes superimposing an inner edge of the reinforcement over a periphery of the electrode, and causing a projecting portion of the reinforcement to project the proton-exchange membrane so as to limit gas permeation into the proton-exchange membrane, and forming filigrees by a wet process in a gas diffusion layer, thereby forming a recess therein, and placing the gas diffusion layer so that the inner edge of the reinforcement extends into the recess in the gas diffusion layer.
