The invention relates to a single or multi-layered plastic membrane doped with acid and comprising at least one layer A of a polymer mixture consisting of a) between 0.1 and 99.9 wt. % of at least one polymer comprising recurrent azole units of general formulae (1A) and/or (1B) - wherein radicals Ar, Ar<1> and Ar<2> represent tetravalent, divalent or trivalent aromatic or heteroaromatic groups, and radicals X, which are the same inside a recurrent unit, represent an oxygen atom, a sulphur atom, or an amino group having a hydrogen atom and a group comprising 1 to 20 carbon atoms, preferably a branched or unbranched alkyl or alkoxy group, or an aryl group as a further radical - mixed with b) between 99.9 and 0.1 wt. % of a polysulfone comprising no sulfonic acid groups but comprising recurrent units of general formulae (2A, 2B, 2C, 2D, 2E, 2F) and/or (2G) wherein radicals R, the same or different, independently represent 1,2-phenylene, 1,3-phenylene, 1,4-phenylene, 4,4'-biphenylene, a divalent radical of a heteroaromatic compound, a divalent radical of a C10-aromatic compound and/or a divalent radical of a C14-aromatic compound. The invention also relates to a method for producing said doped plastic membrane, the use thereof in fuel cells, during electrolysis, in capacitors, in battery systems and in electrochromic applications, in addition to membrane electrode units comprising at least one inventive plastic membrane. |
