Abstract: The present disclosure relates to a method for the production of metal-containing spherically porous carbon particles. For this purpose, a carbon precursor is preferably polymerized with a structure-forming template in a solvent to form a polymer solution in a first step, the metal compound is added to the polymer solution in a second step and finally the metal-containing spherically porous carbon particles are formed in a third step by means of an aerosol spraying method. In addition, the present disclosure relates to a method for producing an ink and a use of the metal-containing spherically porous carbon particles as a catalyst.

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.
