    • A process is disclosed for producing a cation-exchanging membrane. An organic polymer with sulphonic acid groups and finely divided electroconductive particles of a catalyst material is introduced into a liquid phase and the resulting suspension is used to coat at least one side of a foil made of a cation exchanger material. The process is characterised in that the organic polymer with sulphonic acid groups is soluble in an aprotic polar solvent and contains units of formulas (Ar X) and (Ar Y) at least partially substituted by sulphonic acid groups. Ar and Ar stand for identical or different bivalent arylene radicals, X stands for oxygen or sulphur and Y stands for a carbonyl, sulphoxide or sulphonyl radical. This material is dissolved in a solvent, a finely divided electroconductive catalyst material is suspended in the solution and a foil which contains a polymer cation exchanger with sulphonic acid groups is coated with this suspension. The still solvent-containing coating is treated with a liquid miscible with the solvent but in which the dissolved cation exchanger material is not soluble, so that pores are formed in the resulting film that coats the membrane.
