Abstrakt: The composite electrolytes of composition (1 − x)TaH(PO4)2 · 2H2O/ xSiO2 ( x = 0.2–0.4) are synthesized, and their transport properties are characterized over a wide temperature range. Doping with highly dispersed silica only insignificantly changes the proton conductivity of tantalum hydrogenphosphate below 370 K; above 820 K, the conductivity increases. The evolution of the phase composition of TaH(PO4)2 · 2H2O and its base materials during thermolysis is studied. [ABSTRACT FROM AUTHOR]
