BaCe0.7Zr0.1Y0.2-xNdxO3-? Proton Conducting Electrolyte for Intermediate Temperature Solid Oxides Fuel Cells

摘要

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-冊 (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-冊 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-冊 proton conducting electrolyte at 650-700 Oc efficiently co-produces electrical power and value-added ethylene from ethane.
