La₀.₈Sr₀.₂CoO₃ is a perovskite-based mixed oxide ceramic composed of lanthanum, strontium, and cobalt. This material is primarily investigated as a cathode material for solid oxide fuel cells (SOFCs) and oxygen permeation membranes, where it offers improved electrochemical activity and oxygen reduction kinetics compared to conventional cathode materials. The strontium doping enhances electrical conductivity and sintering behavior, making it a candidate for intermediate-temperature fuel cell operation and applications requiring controlled oxygen transport.
