Zusammenfassung:Time-stable proton-conducting gel electrolytes based on poly(methyl methacrylate) doped by o -phosphoric acid solutions of different concentrations in DMF are prepared. The dependences of the electrical conductivity of the gels on the concentrations of the acid and polymer and the molecular mass of PMMA at 25–65°C are studied. The thermal stability of electrolytes is estimated. It is found that an increase in the content of the polymer in gels changes the thermal behavior of the samples.
