PRODUCTION OF A CATALYTICALLY COATED ANION EXCHANGE MEMBRANE

Absstract of: CA3317661A1

The invention concerns catalytically coated anion exchange membranes and the production thereof. The catalytically actively coated anion exchange membranes are used in electrochemical cells, in particular for water electrolysis. It is an object of the invention to specify a process for producing an electrocatalytically actively coated anion exchange membrane, the coating of which is porous, and hence the electrocatalytically active sites present in the coating have good accessibility by the reactants. A basic idea of the process according to the invention is to incorporate particulate inorganic material into the catalyst coating as spacer, to consolidate the coating and then to leach the inorganic material back out of the coating. The leaching transforms the inorganic material to a water-soluble product that can easily be washed out of the coating. What are left are cavities (pores) at the sites where the particulate inorganic material was previously present within the coating. The inorganic material therefore assumes the function of a structure definer within the coating composition, which is lost in the course of catalytically active coating.
