The perovskite La 0.75 Sr 0.25 Cr 0.5 Mn 0.3 Ni 0.2 O 3−δ (LSCMMn 0.30 Ni 0.20 ) was evaluated as potential electrode for solid oxide fuel cells. The electrochemical performances of LSCMMn 0.30 Ni 0.20 for hydrogen oxidation and oxygen reduction reactions were studied at 800°C. Symmetrical cells LSCMMn 0.30 Ni 0.20 /YSZ/LSCMMn 0.30 Ni 0.20 were studied by electrochemical impedance spectroscopy. The total conductivity of LSCMMn 0.30 Ni 0.20 is 22S cm −1 in air and 0.8S cm −1 under wet 5% H 2 /Ar at 800°C. The area specific resistance (ASR) at 800°C for hydrogen oxidation reaction is 1Ω cm 2 . The ASR for oxygen reduction reaction is 1.6Ω cm 2 . An ageing study during 24h shows a relatively good stability of the electrochemical performances. LSCMMn 0.3 Ni 0.2 seems to be a promising dual electrode for a symmetrical SOFC.
