Recently partially strontium substituted lanthanum ferrites, La1-xSrxFeO3-δ have been proposed as suitable alternative cathodes for intermediate temperature solid oxide fuel cells (ITSOFCs). In this study, La deficient - La0.65Sr0.30FeO3-δ (LSF) perovskite oxide material was synthesized by a simple wet chemical route and systematically characterized by XRD, TGA-DTA, FTIR, particle size analysis and SEM. The sintering properties of the LSF circular components were studied and are reported. The electrical properties of the LSF specimens were studied by a four probe DC technique in air. From the electrical characterization studies, it was found that the conductivity values of the LSF specimens increased with an increase in temperature and reached a maximum value of 153.41 Scm-1 at 769 K. Hence, this new type of material may be considered as a suitable alternative candidate cathode material for ITSOFC application.
