The results demonstrate that, in a wide temperature range, the proton conductivity of the films reaches a maximum at x = 1.5. The activation energy of conductivity in the films, equal to 0.1–0.2 eV at low temperatures, rises upon partial dehydration above 100 °C. The possible mechanisms of proton formation and transport are discussed Полный текст |
