    YBaCuO-type perovskites as potential air electrodes for SOFCs. The case of YSr2Cu2FeO7+δ
    (Journal of Materials Chemistry A, 2021) López Paz, Sara Almudena; Marín Gamero, Rafael; Martínez De Irujo Labalde, Xabier; Sánchez Marcos, Jorge; Perez Coll, Domingo; Alario y Franco, Miguel Ángel; García Martín, Susana
    The electrochemical properties of YSr2Cu2FeO7+d with YBaCuO-type structure have been studied. The temperature dependent oxygen content of this oxide has a marked influence on its p-type conducting behavior, since topochemical oxygen release occurs on heating above 673 K while reversible oxygen uptake takes place on cooling. Mixed valence Fe3+/Fe4+ and Cu2+/Cu3+ in combination with anion vacancies within the oxygen-sublattice suggest mixed (electronic and ionic) conductivity in this oxide. Electrochemical measurements indicate that YSr2Cu2FeO7+d shows high oxygen reduction reaction activity at intermediate temperatures, revealing its potential applications as an air electrode in SOFCs.
