Evaluation of stability and functionality of BaCe1?xInxO3?? electrolyte in a wider range of indium concentration

Abstract The properties of BaCe 1? x In O 3? ? ( = 0.05, 0.10, 0.15, 0.20, 0.25, 0.30, 0.35, and 0.40) as proton conducting electrolyte are examined. dense is formed after sintering at 1300 °C for 5 h in air. samples with content ? 25 mol% contain 2 3 a secondary phase. highest total conductivity around 5×10 ?3 S/cm 0.75 0.25 the wet hydrogen atmosphere 700 °C. After exposure to pure CO h, concentrations least 15 can completely suppress degradation electrolyte. power density Ni-BaCe /BaCe /LSCF-BaCe fuel cell tested reaches 264 mW/cm This result an indication stability functionality this its versatility respect type performing environment.
