Abstract
A method for manufacturing an MEA including a layer system, the layer system together with a plastic film located above and below it being punched out by a heated and shaped punching tool. The film-coated layer system, which is welded together only at the outer edges, is further processed by heating and pressing the marginal zones in a subsequent operation, the plastic film softening or melting in the marginal zone and penetrating the marginal regions. Thus, the marginal region in the periphery of the layer system is sealed in a gas-tight manner within seconds. The film inside the marginal zones which is no longer needed or not heated is removed by suction.
