COATING OF CATION EXCHANGE MEMBRANES

Resumen de: AU2024262986A1

The invention relates to the coating of cation exchange membranes with catalytically active substances. The catalytically actively coated cation exchange membranes are used in electrochemical cells, especially in fuel cells (proton exchange membrane fuel cells - PEMFC) or in electrolysers for water electrolysis (polymer electrolyte membrane water electrolysis - PEMWE). In order to counteract the disadvantages of conventional decal processes, an alterative process for coating cation exchange membranes was sought which enables the transfer of electrocatalysts without the need for high temperatures, high pressures and PFAS-based substrates. It was surprisingly found that catalyst layers which are treated, shortly before the transfer step, with a polymer-swelling solvent conducting the cations can be transferred far more easily.
