Abstract

A method for producing a catalyst-coated polymer membrane for an electrolyser and/or a fuel cell includes steps including providing a glass-ceramic substrate and synthesizing a mesoporous catalyst layer on the glass-ceramic substrate. The steps include pressing a polymer membrane onto the glass-ceramic substrate coated with the catalyst layer at a first temperature T1, thereby producing a sandwich structure. The steps further include separating the sandwich structure. The catalyst layer is separated from the glass-ceramic substrate and adheres to the polymer membrane.
