摘要

可逆对称固体氧化物电池(RS-SOC)因其能量转换效率高、制造简单而备受关注。通式为 A2BB'O6 的双过氧化物常被用作电极材料。在本研究中,Sr1.9Fe1.5Mo0.5O6-δ的 B 位用钯取代了铁,使其电化学性能提高了 50%以上。表征结果表明,掺杂钯促进了电极反应动力学,从而提高了电化学活性。在固体氧化物燃料电池(SOFC)中,La0.9Sr0.1Ga0.8Mg0.2O3-δ(LSGM)支撑的对称电池与 Sr1.9Fe1.45Pd0.05Mo0.5O6-δ 电极在 800 ℃ 时的最大功率密度达到了 870 mW cm-2。

High-performance Sr1.9Fe1.45Pd0.05Mo0.5O6−δ electrode for reversible symmetrical solid oxide cells
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).
