Abstract[English]
A catalyst-coated membrane-seal assembly comprises an ion-conducting membrane with a central region, which has a first catalyst layer on a first side and a second catalyst layer on the second side, and a border region which has a first seal material layer on the first side and a second seal material layer on the second side. The edge of the first seal material layer facing the central region is bevelled such that a side of the first seal material layer extends further towards the central region than the opposite side of the first seal material layer.[French]
Ensemble membrane-joint revêtu de catalyseur comprenant une membrane conductrice d'ions ayant une région centrale, qui a une première couche de catalyseur sur un premier côté et une seconde couche de catalyseur sur le second côté, et une région bordure qui a une première couche de matériau d'étanchéité sur le premier côté et une seconde couche de matériau d'étanchéité sur le second côté. Le bord de la première couche de matériau d'étanchéité en regard de la région centrale est biseauté de manière à ce qu'un côté de la première couche de matériau d'étanchéité s'étende davantage en direction de la région centrale que le côté opposé de la première couche de matériau d'étanchéité.
