Abstract:
The invention relates to polymers comprising sulfonated 2,6-diphenyl-1,4-phenylene oxide repeating units, to a method for their preparation, and to their use in a membrane electrode assembly, in a proton exchange membrane, in a fuel cell, in an electrolyser, in an electrolytic hydrogen compressor or in a flow battery. The invention further relates to a proton exchange membrane comprising said polymer and to a method for the preparation of a proton exchange membrane from said polymer. The invention also relates to the use of the polymers in ion exchange materials.
