The invention relates to catalytically coated anion exchange membranes and their production. The catalytically active coated anion exchange membranes are used in electrochemical cells, in particular for water electrolysis. The object of the invention was to provide a process for producing an electrocatalytically active coated anion exchange membrane whose coating is porous and thus the electrocatalytically active centers located in the coating are easily accessible to the reactants. A basic idea of the process according to the invention is to incorporate particulate inorganic material into the catalyst coating as a placeholder, to solidify the coating, and then to leach the inorganic material out of the coating. The leaching converts the inorganic material into a water-soluble product that can be easily washed out of the coating.What remains are voids (pores) where the particulate inorganic material was previously located within the coating. The inorganic material therefore assumes the function of a structure-imparting agent within the coating composition, which is lost during the catalytically active coating process.
