A Review on the Process-Structure-Performance of Lanthanum Strontium Cobalt Ferrite Oxide for Solid Oxide Fuel Cells Cathodes

Perovskite-structured La1-xSrxCo1-yFeyO3-δ (LSCF) is a promising mixed ionic/electronic-conducting material that exhibits excellent electro-catalytic activity toward oxygen reduction and evolution reactions. LSCF offers potential applications in many processes, such as electrodes for solid oxide fuel cells (SOFCs), sensors, dense membrane separation thus have been studied extensively various fields. However, its physical electrochemical properties are substantially influenced by dopant concentration, type processing conditions (synthesis methods, composite cathode effect, fabrication conditions, chromium poisoning). Understanding correlating the effect of composition, synthesis parameters essential to enhance performance high- to- intermediate temperature SOFC applications. This review emphasizes importance enhancing optimizing influential factors facilitate expedite research development efforts commercialization near future. Various methods used prepare fabricate LSCF-based cathodes discussed detail. Moreover, their pros cons microstructure highlighted. Finally, strategies improve long-term microstructural stability performances discussed.
