摘要：

The electrochemical performance of solid oxide fuel cells (SOFCs) based on perovskite-type materials (ABO(3)) was investigated. La0.9Sr0.1Ga0.8Mg0.2O3-delta (LSGM) ceramics were used as electrolyte and a composite containing La0.8Sr0.2MnO3 (LSM) as cathode. Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) was also used as cathode and La0.75Sr0.25Cr0.5MnO3-delta (LSCM) as anode materials. Furthermore, fluorite-type SM0.15Ce0.85O2-delta (SDC) material was used as buffer layer between the electrolyte and the anode to avoid possible interfacial reactions. The maximum power density value of BSCF/LSGM/LSCM with 1.5 mn thick electrolyte supported cell was 160 mW cm(-2) at 1073 K, using moist H-2 diluted with N-2 as fuel and air as oxidant.
