Résumé     
The perovskite La0.75Sr0.25Cr0.5Mn0.3Ni0.2O3 (- delta) (LSCMMn0.30Ni0.20) was evaluated as potential electrode for solid oxide fuel cells. The electrochemical performances of LSCMMn0.30Ni0.20 for hydrogen oxidation and oxygen reduction reactions were studied at 800 degrees C. Symmetrical cells LSCMMn0.30Ni0.20/YSZ/LSCMMn0.30Ni0.20 were studied by electrochemical impedance spectroscopy. The total conductivity of LSCMMn0.30Ni0.20 is 22 S cm(-1) in air and 0.8 S cm(-1) under wet 5\% H-2/Ar at 800 degrees C. The area specific resistance (ASR) at 800 degrees C for hydrogen oxidation reaction is 1 Omega cm(2). The ASR for oxygen reduction reaction is 1.6 Omega cm(2). An ageing study during 24 h shows a relatively good stability of the electrochemical performances. LSCMMn0.3Ni0.2 seems to be a promising dual electrode for a symmetrical SOFC. (C) 2010 Elsevier B.V.
