A BaFe0.9Zr0.1O3-δ (BFZ) is successfully synthesized and its characteristics are investigated. The oxide exhibits high stability and a cubic perovskite structure in a reducing atmosphere. A La0.9Sr0.1Ga0.8Mg0.2O3-δ (LSGM) supported symmetrical solid oxide fuel cell (SOFC) with BFZ electrode demonstrates a maximum power density of 1097 mW cm−2 using humidified H2 as the fuel and ambient air as the oxidant at 800 °C. And as low as 0.190 Ω cm2 of polarization resistance of single cell is observed at 650 °C. Moreover, the electrode demonstrates high stability in 100 h test, as well as redox stability in both oxidizing and reducing atmospheres. The high electrochemical property and good stability suggest that the BFZ is promising candidate for symmetrical SOFC electrode.
