Abstract: The sinterability, conductivity and chemical stability in CO2 atmosphere are compared for a series of doped barium cerate perovskite oxides BaCe0.7Zr0.1Y0.2-xNdxO3-? (0 ≤ x ≤ 0.2) which synthesized using a solid state reaction method. Among the series of electrolytes doped with various amounts of Nd and Y, BaCe0.7Zr0.1Y0.15Nd0.05O3-? has the optimal combination of sinterability and conductivity, and shows high CO2 resistance. A solid oxide fuel cell using the BaCe0.7Zr0.1Y0.15Nd0.05O3-? proton conducting electrolyte at 650-700 oC efficiently co-produces electrical power and value-added ethylene from ethane.
