Method for producing a membrane electrode assembly for a fuel cell, and production line

Abstract

A method for manufacturing a membrane electrode assembly for a fuel cell, comprising a membrane, two reinforcers, two seals, gas diffusion layers and a catalyst, comprises the following steps: a step during which a seal is applied to each of the reinforcers using screen printing, a step during which a catalytic chemical element is applied to the membrane, a step during which a reinforcement bearing a screen-printed seal is thermally bonded to each of the faces of the catalysed membrane, and a step during which a gas diffusion layer is applied to each of the faces of the catalysed membrane bearing a reinforcer and a seal, the method being such that the various elements are held on a support by suction during at least some of the steps of the method. There is also a corresponding production line.
