Abstract (en)

[origin: CA2613190A1] The invention relates to the following: a method for production of aqueous formulations (A) containing at least one polyaromatic particularly sulphonat ed compound with acid groups and aqueous formulations (A), produced by said method; a method for production of dried formulations (B) by removal of the water from aqueous formulations (A) and the dried formulation (B) itself; a formulation (C), comprising said dried formulation (B) and water or the formulation (A) and a water-containing formulation (D) containing the aqueou s formulation (A) or the formulation (C) and in addition at least 2 wt. % of a n organic solvent; a dry formulation (E), obtained by removal of water and solvent from the aqueous formulation (D); the use of aqueous formulation (D) and the dry formulation (E) obtained therefrom for the production of a polym er electrolyte membrane itself and a membrane/electrode unit (MEA) and a fuel cell comprising said polymer electrolyte membrane.
