Résumé

The acceptor-substituted BaSn_0.875M_0.125O _3-δ (M = Sc, In, Y, and Gd) proton conductors were prepared by a wet chemical method. The effects of dopant nature on the structure, hydration energy and proton conduction have been investigated. Analysis of XRD data showed that all compounds present a cubic perovskite structure (space group: Pm3-m). Thermogravimetry analysis showed that the significant mass of water was gained in wet Ar during measurements, and the most negative hydration energy is observed for Sc-substituted BaSnO₃ (-86 kJ/mol). However, Y-substituted BaSnO₃ exhibits the highest proton conductivity at low temperature under wet Ar, such as the total conductivity is 4.8 × 10 ^-4 S/cm at 600 °C.
