Abstract
The invention relates to a method for manufacturing a membrane/electrode assembly, including the steps of: providing a proton exchange membrane comprising a first electrode and a second electrode; placing a first reinforcement with an overlapping portion vertically adjacent to the periphery of the membrane, and with an extension portion made of a polymer material extending laterally beyond the membrane; placing a second reinforcement with an overlapping portion that is vertically adjacent to the periphery of the membrane, and with an extension portion of said second reinforcement extending laterally beyond the membrane and being vertically adjacent to the extension portion of the first reinforcement; applying a laser beam to the vertically adjacent extension portions such as to define an opening through the extension portions and such as to weld the extension portions.
