摘要： A method for preparing a cation exchange membrane, comprising the introduction of an organic polymer having sulfonic acid groups and of finely disperse electrically conductive particles of a catalyst material into a liquid phase, the resulting suspension being used to coat a foil of a cation exchange material on at least one side, wherein the organic polymer having sulfonic acid groups is soluble in an aprotic polar solvent and contains units of the formulae (Ar1X) and (Ar2Y) which are at least partially substituted by sulfonic acid groups, Ar1 and Ar2 being identical or different bivalent arylene radicals, X being oxygen or sulfur and Y being a carbonyl radical, sulfoxide radical or sulfonyl radical and said material being dissolved in a solvent, a finely disperse electrically conductive catalyst material being suspended in the solution and this suspension being used to coat a foil which contains a polymeric cation exchanger having sulfonic acid groups and the coating which still contains solvent being treated with a liquid which is miscible with the solvent, but in which the dissolved cation exchange material is insoluble, so that pores are formed in the top layer of the membrane.

摘要： A process for producing laminates which contain at least one centrally arranged, ion-conductive membrane which is, at least over a substantial part of its two mutually opposite flat faces, electrically conductively bonded to at least one catalytically active substance and to at least one two-dimensional, gas-permeable, electron-conductive contacting material, the bonding of at least two of the said components having been effected by lamination. The process comprises carrying out the bonding of the ion-conductive membrane, of the catalytically active substance and of the electron-conductive contacting material continuously. The ion-conductive membrane is brought together with at least the electron-conductive contacting material in the exact position by means of transport and feeding devices and the two components are laminated and bonded to one another by pressing them together. The range of variation in the a.c. resistances of the laminates produced by the process according to the invention is ±10%. The laminates are particularly suitable for use in fuel cells or electrolysers.
