Abstract

A layered perovskite PrBa(Fe_0.8Sc_0.2)₂O_5+δ (PBFSc) is applied as both cathode and anode in the symmetrical solid oxide fuel cells (SOFCs) field and its electrochemical properties are investigated. La_0.9Sr_0.1Ga_0.8Mg_0.2O_3-δ (LSGM) supported symmetrical cell with PBFSc electrode exhibits polarization resistances of 0.05 Ω cm² in air and 0.18 Ω cm² in wet H₂ at 800 °C. A maximum power density of 921 mW cm⁻² is obtained using wet H₂ as the fuel and ambient air as the oxidant at 850 °C. Moreover, the electrode demonstrates good redox stability in both oxidizing and reducing atmospheres. The layered perovskite PBFSc with favorable performance characteristics is shown to be an effective, redox-stable electrode candidate that can be used for both cathode and anode.
