A Keggin-type vanadium-substituted tungstovanadozincic heteropoly acid H 7 ZnW 11 VO 40 ⋅ 8 H 2 O , with the transition metal as central atom, was firstly synthesized and characterized. Its proton conductivity was measured by the electrochemical impedance spectrum (EIS), and the result indicates that the H 7 ZnW 11 VO 40 ⋅ 8 H 2 O is a solid high-proton conductor with conductivity of 3.26 × 10-3S ⋅ cm-1 at 58°C, 50% relative humidity. Its activation energy is 29.50 kJ ⋅ mol-1, which suggests that the mechanism of proton conduction is the Vehicle mechanism.
