Abstract: The invention relates to a method for producing a catalyst-coated polymer membrane for an electrolyser and/or a fuel cell. In a first step, the method preferably comprises the provision of a glass-ceramic substrate. A mesoporous catalyst layer is then preferably synthesized on the glass-ceramic substrate. In a next step, a polymer membrane is preferably pressed onto the glass-ceramic substrate coated with the catalyst layer at a first temperature T1. This results in a sandwich structure. In a final process step, the sandwich structure is separated, the catalyst layer being separated from the glass-ceramic substrate and adhering to the polymer membrane.
In addition, the invention relates to a polymer membrane which has been produced by the process of the type mentioned at the outset, and to an electrolyser or a fuel cell having such a polymer membrane.
