摘要： Die Erfindung befasst sich mit dem Beschichten von Kationenaustauschmembranen mit katalytisch aktiven Substanzen. Die katalytisch aktiv beschichteten Kationenaustauschmembranen werden in elektrochemischen Zellen eingesetzt, insbesondere in Brennstoffzellen (engl.: Proton Exchange Membrane Fuel Cells - PEMFC) oder in Elektrolyseuren zur Wasserelektrolyse (engl.: Polymer Electrolyte Membrane Water Electrolysis - PEMWE). Um den Nachteilen von herkömmlichen Decal-Prozesses entgegenzuwirken, wurde nach einem alternativen Prozess zur Beschichtung von Kationenaustauschmembranen gesucht, der einen Transfer von Elektrokatalysator ermöglicht, ohne hohe Temperaturen, hohe Drücke und PFAS-basierte Substrate zu benötigen. Es wurde überraschend gefunden, dass sich Katalysatorschichten, die kurz vor dem Übertragungsschritt mit einem das Kationen leitende Polymer quellenden Lösungsmittel behandelt wurden, deutlich einfacher übertragen lassen.
