Barium cerate doped by trivalent rare earth metal ions is a potentially huge component of materials for electrochemical industry due to its high protonic conductivity. However, the poor chemical stability especially in the presence of CO 2 , SO 2 or H 2 O, resulting in decreasing the mechanical durability of obtained materials, limits their possible applications. The new approach towards stable ceramic protonic conductors with high electrical conductivity is presented. Thermal stability of yttrium doped (10 mol%) of BaCeO 3 was enhanced by forming the composite material BaCe 0.9 Y 0.1 O 3 -BaWO 4 (10 mol% of BaWO 4 ). The synthesis was performed by solid-state reaction method. The detailed study of thermal decomposition of starting powders mixture was performed using thermogravimetry and differential thermal analysis (TG/DTA) techniques combined with Evolved Gas Analysis (EGAmass spectrometry). Structure, phase composition and microstructure together with thermal stability of sintered materials were determined. The exposition tests were performed to characterise the stability of composites in carbon dioxide and water vapour-rich atmospheres. The samples were exposed to atmosphere containing CO 2 /H 2 O (7 % of CO 2 in air, 100 % RH) at temperature of 25°C for 300 h. Thermal analysis supplied with mass spectrometry was applied to analyse the materials after the test. The results of this experiment showed better chemical resistance of composite material-BaCe 0.9 Y 0.1 O 3 with 10 mol% of BaWO 4 compared to single phase material.

“…These materials have to satisfy specific criteria for effective operation at low and moderate temperatures such as high ionic conductivity and ionic transport number, chemical and physical stability at the operating conditions, accessibility and low cost of raw materials and easy mass production [5]. Therefore, they have various applications in electrochemical devices such as all solid-state batteries, fuel cells, electrochomic devices and smart windows.…”
