The catalytically actively coated cation exchange membranes are used in electrochemical cells, especially in fuel cells (proton exchange membrane fuel cells - PEMFC) or in electrolysers for water electrolysis (polymer electrolyte membrane water electrolysis - PEMWE).

It was surprisingly found that catalyst layers which are treated, shortly before the transfer step, with a polymer-swelling solvent conducting the cations can be transferred far more easily.
