摘要： The present invention relates to a process for preparing aqueous formulations (A) comprising at least one polyaromatic compound bearing acid groups, in particular a sulfonated polyaromatic compound, and also aqueous formulations (A) which have been prepared by the process of the invention. Furthermore, the present invention relates to a process for preparing dried formulations (B) by removing the water from the aqueous formulations (A) and also the dried formulations (B) themselves. The present invention further provides a formulation (C) comprising the dried formulation (B) of the invention and water or the formulation A of the invention and a water-comprising formulation (D) comprising the aqueous formulation (A) or the formulation (C) of the invention and additionally at least 2% by weight of an organic solvent. Furthermore, the present invention relates to dry formulations (E) which are obtained by removing water and solvent from the water-comprising formulations (D) of the invention. The present invention further provides for the use of the water-comprising formulations (D) of the invention and of the dry formulations (E) obtained from these for producing a polymer electrolyte membrane and also the polymer electrolyte membrane itself and a membrane-electrode assembly (MEA) and also a fuel cell comprising the polymer electrolyte membrane of the invention.

摘要： The invention relates to a method for producing a uniform flow through an electrolyte space of an electrolysis cell, in which a maximum deviation of less than 1% to 25% from the average flow rate is achieved by suitable design measures. The invention also relates to an electrolysis cell with at least two electrolyte spaces, in each of which at least one electrode is arranged and each of which has an inlet region and an outlet region, the flow cross section being reduced in the inlet and/or outlet region so as to produce an additional pressure reduction
