By the method of impregnation from solution the compounds were introduced into the composition of polysulfone or track polyethylene terephthalate membranes of a given porosity. The developed membranes are characterized by thermal stability up to 270oC and ionic conductivity level of 10-5-10-4 S/cm at 120oC under anhydrous conditions and are promising for polymer-electrolyte fuel cells for operation at 100-200oC.
