The invention relates to catalytically coated anion exchange membranes and to the production thereof. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The invention addresses the problem of providing a method for producing an electrocatalytically actively coated anion exchange membrane, the coating of which is porous and thus the electrocatalytically active centres located in the coating are easily accessible for the reactants. A basic concept of the method according to the invention consists in incorporating particulate inorganic material into the catalyst coating as a placeholder, solidifying the coating, and subsequently leaching the inorganic material out of the coating again. As a result of the leaching, the inorganic material is converted into a water-soluble product which can easily be washed out of the coating. Cavities (pores) remain at the points where the particulate inorganic material was previously located within the coating. Within the coating composition, the inorganic material therefore assumes the function of a structuring means which is lost in the course of the catalytically active coating.
