Abstract
Reversible symmetrical solid oxide cells (RS-SOCs) have attracted much attention due to their high energy conversion efficiency and fabrication simplicity. The double perovskite with the general formula A2BB’O6 is often used as the electrode material. In this study, Fe was substituted with Pd in the B-site of Sr1.9Fe1.5Mo0.5O6−δ to enhance the electrochemical performance above 50 %. The characterization results showed that the doping of Pd promoted the kinetics of the electrode reaction and thus improved the electrochemical activity. A maximum power density of 870 mW cm−2 at 800 ℃ on a La0.9Sr0.1Ga0.8Mg0.2O3–δ (LSGM)-supported symmetrical cell with Sr1.9Fe1.45Pd0.05Mo0.5O6-δ electrode was achieved in the solid oxide fuel cells (SOFCs).
