Abstract
A method for producing membrane-electrode assemblies () for a fuel cell unit () as a fuel cell stack (), comprising the following steps: providing in each case one proton exchange membrane (), providing in each case one first subgasket () as sealing layer (), providing in each case one second subgasket () as sealing layer (), arranging the in each case one proton exchange membrane () between the in each case first and in each case second subgasket (), connecting the in each case one proton exchange membrane () to the in each case first and/or in each case second subgasket (), such that in each case one layered inner region () of the in each case one proton exchange membrane () is enclosed by the in each case one first and second subgasket () as sealing layers (), wherein the proton exchange membranes (), the first subgaskets (), and the second subgaskets () are provided in that they are removed as proton exchange membrane strip (), first subgasket strip (), and second subgasket strip () from storage devices () and the arrangement of the proton exchange membranes () between the first and second subgaskets () and the connection of the proton exchange membranes () to the first and/or second subgaskets () are configured in the state of the first subgaskets () as first subgasket strip () and of the second subgasket () as second subgasket strip (), such that, during the arrangement and connection, the first subgaskets () are arranged connected to one another on the first subgasket strip () and the second subgaskets () are arranged connected to one another on the second subgasket strip ().
