Abstract
A method for the dry production of a membrane-electrode unit includes assembling a layered configuration including a centrally positioned membrane produced by extrusion and pre-dried at a temperature between 80° C. and 100° C. for 15 min to 30 min, a substrate-electrode unit on each side of the membrane having an electrode layer applied to a substrate, an optional frame around each substrate-electrode unit for fixing the substrate-electrode unit, and two separating films on outer sides. The configuration is pressed together between two laminating rollers so that a pressure connection is produced at least between the membrane and the electrode layers. A short production time is achieved because it is not necessary to keep the membrane moist at high temperatures under pressure. A membrane electrode unit and a roller configuration are also provided.
