Effects of Al2O3 doping in BaCeO3 on chemical stability and electrical conductivity of proton conducting oxides

BaCeO3 doped with trivalent ions have high proton conductivity but poor chemical stability against CO2. Al-doped BaCeO3 (Ba(Ce1−xAlx)O3−δ) was fabricated via conventional solid oxide reactions, and their chemical stabilities against CO2 and electrical conductivities were compared with those of Y-dop...
