The present invention provides a continuous process for producing catalyst-coated polymeric electrolyte membranes and membrane electrode assemblies for fuel cells. The process of the invention uses an ionomer membrane having a polymeric backing film on the back side. After the first coating step, the membrane is dried, during which the residual solvent may be almost completely removed. After this, the polymeric backing film is removed and the back side of the membrane is coated in a second step. The front and back sides of the membrane can be coated by various methods, such as screen printing or stencil printing. Two gas distribution layers are applied to the two sides of the catalyst-coated membrane to produce a 5-layer membrane electrode assembly. The membrane electrode assemblies are used in polymeric electrolyte membrane fuel cells and in direct methanol fuel cells.
