Process for manufacturing of catalyst coated membranes and membrane electrode units for fuel cells

The method for producing, for fuel cells, a polymer electrolyte membrane in the form of a tape coated on both sides with a catalyst involves use of a membrane with a support foil on its rear side, application (with use of a catalyst ink) of an electrode layer to the front side of the membrane, drying of this layer at an elevated temperature, and removal of the support foil from its rear side. The production process is completed by application of an electrode layer to the rear side of the membrane, drying of this layer, and finish treatment of the resultant membrane with water at an elevated temperature. An Independent claim is also included for an application of the proposed method for production of membrane electrode units.
