Abstract: The invention relates to a method for the production of aqueous formulations (A), comprising at least one acid group and/or salts of acid group-carrying polyaromatic compounds and aqueous formulations (A), produced according to the inventive method. The invention further relates to a method for the production of dried formulations (B) by removing the water from the aqueous formulations (A) and to the dried formulations (B). Furthermore, the invention relates to a formulation (C) comprising the inventive dried formulation (B) and water, or an aqueous formulation (A) and a water-containing formulation (D) comprising the inventive aqueous formulation (A) or the inventive formulation (C) and additionally at least 2 wt.% of an organic solvent. The invention further relates to dry formulations (E), obtained from the inventive aqueous formulations (D) by removing water. And it relates to the use of the inventive aqueous formulations (D) and the dry formulations (E) obtained thereof for the production of a polymer electrolyte membrane and the polymer electrolyte membrane and a membrane electrode unit (MEA) and a fuel cell, comprising the inventive polymer electrolyte membrane.

Abstract: The invention relates to a method for producing membranes coated with a catalyst on both sides for electrochemical devices, with the following steps: A) producing a first semifinished product by applying a first ionomer layer onto a first support, applying an anode catalyst layer onto the first ionomer layer while using a first catalyst ink, and drying the anode catalyst layer; B) producing a second semifinished product by applying a second ionomer layer onto a second support, applying a cathode catalyst layer onto the second ionomer layer while using a second catalyst tint, and drying the cathode catalyst layer; C) removing the first and second supports from the first or second ionomer layer and, joining the first semifinished product to the second semifinished product by joining the first ionomer layer to the second ionomer layer.
