Abstract

This study focuses on the synthesis, characterization, and study of new perovskite-type materials as cathodes in SOFC. The doped perovskites were successfully synthesized with high purity. The electrochemical performance of these materials was extensively examined through the characterization of I-V-P and EIS curves at the three temperatures, 750, 800, and 850 °C, where it reveals a substantial reduction in total resistances, accompanied by an impressive increase in power densities. The cell featuring La0.01Sr0.99Co0.5Fe0.5O3 exhibited the most commendable electrochemical properties at each temperature, following which were SrCo0.5Fe0.5O3, Pr0.01Sr0.99Co0.5Fe0.5O3, and Sm0.01Sr0.99Co0.5Fe0.5O3.
