A novel electrolyte membrane PVDF-Al2O3-CsHSO4 usable at medium temperatures was prepared by composite of PVDF and an inorganic proton conductor Al2O3-CsHSO4. The membrane has a steep increase in proton conductivity around 90°C and retains the high conductivity, about 10-3 S•cm-1, up to 200°C. The incorporation of Al2O3-CsHSO4 with PVDF leads to a dramatic improvement of the properties of PVDF, including widen the phase transition temperature of CsHSO4, improve proton conductivity and enhance chemical stability over wide temperature range.

A novel 2D nickel(ii) complex (1) has been successfully synthesized using a 2,2′-bipyridyl, polycarboxylsulfonate ligand H4SBTC and Ni2+ ions. Owing to the presence of abundant water molecules, hydrogen bond networks and other protons, 1 and its hybrid membranes demonstrate high proton conductivity.

Through cation substitution in a zirconium based coordination polymer, an isostructural framework 1@NH4+ has been prepared without any apparent structural change. The proton conductivity of 1@NH4+ is successfully improved. It exhibits high proton conductivity (1.39 × 10−2 S cm−1) at 98% relative humidity and 60 °C.
