Abstract
(La,Sr)MnO3+δ (LSM)-based perovskite oxides have attracted great attention as oxygen electrodes for reversible solid oxide cells (RSOCs) owing to excellent comprehensive properties. Herein, we reported a Sr-free LaMn0.6Co0.2Cu0.2O3-δ (LMCC622) oxide without the side effects of Sr-containing oxygen electrodes and then characterized the electrochemical performance. The coupling of multiple Mn-site transition metal cations in LaMnO3+δ can result in the phase transition from the hexagonal perovskite to the orthorhombic perovskite. The increased thermal reduction of Mn ions in operation temperature releases large amounts of lattice oxygen, dramatically enhancing the catalytic activity of the oxygen electrode. Prepared anode-supported single cells with LMCC622 oxygen electrode exhibited high electrochemical performance (851.12 mW cm−2 at 800 °C), which is higher than that of La0.8Sr0.2MnO3-δ oxygen electrode (682.18 mW cm−2 at 800 °C). The further composite Gd0.1Ce0.9O1.95 (GDC) to LMCC622-GDC as oxygen electrode achieves excellent performance (1211.10 mW cm−2 at 800 °C) and stable cyclable operation of over 100 h in fuel cell and electrolysis cell mode.
