Die Erfindung befasst sich mit dem Beschichten von Anionenaustauschmembranen (AEM) mit katalytisch aktiven Material. Die so erhaltenen CCM werden in elektrochemischen Zellen eingesetzt, insbesondere zur alkalischen Wasserelektrolyse. Der Erfindung lag die Aufgabe zu Grunde, ein Verfahren zur Herstellung einer CCM durch Direktbeschichtung anzugeben, welches die notwendige Ebenheit der AEM erhält und möglichst ohne die Verwendung von verlorenen Folien und ohne CMR-Stoffe auskommt. Weiter soll die Quellung minimiert werden. Auch soll das Verfahren mit fluorfreien lonomeren durchführbar sein. Die Erfindung beruht auf der Erkenntnis, dass die Zugabe bestimmter organischer Substanzen dazu führt, dass die AEM nicht oder lediglich geringfügig quillt (Antiquellmittel). Überraschenderweise hat sich herausgestellt, dass sich als Antiquellmittel geeignete Substanzen anhand ihres Löslichkeits-verhaltens identifizieren lassen, genauer gesagt, anhand ihrer Hansen-Parameter.
