چکیده انگلیسی
The electrochemical performance of solid oxide fuel cells (SOFCs) based on perovskite-type materials (ABO3) was investigated. La0.9Sr0.1Ga0.8Mg0.2O3−δ (LSGM) ceramics were used as electrolyte and a composite containing La0.8Sr0.2MnO3 (LSM) as cathode. Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) was also used as cathode and La0.75Sr0.25Cr0.5Mn0.5O3−δ (LSCM) as anode materials. Furthermore, fluorite-type Sm0.15Ce0.85O2−δ (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 mm thick electrolyte supported cell was 160 mW cm−2 at 1073 K, using moist H2 diluted with N2 as fuel and air as oxidant.
