- Abstract
- Doped-BaCeO3 has high protonic conductivity at intermediate temperature, but poor chemical stability. In contrast, doped-BaZrO3 is rather stable, but has poor protonic conductivity. In this study, the BCY-BCZY bi-layer system was investigated in the hope of the synergetic improvement of high conductivity and good chemical stability. Nano-sized the BCY and modified-BCZY powders were prepared by the citric-nitrate route and bi-layer electrolyte made of BCY covered with a thin film BCY-BCZY deposited by the electrostatic slurry spray deposition. The improvement of chemical stability, measured in CO2 atmosphere, is turned out to be resulted from the substitution of Zr4+ cation. Overall, the BCY-BCZY bi-layer electrolyte shows promising improvement in chemical stability against produced water on the cathode side during the cell operation.
