In response to pressing environmental concerns and the ever-increasing global energy demand, the pursuit of sustainable energy sources has garnered substantial momentum. A predominant focus of research within this domain revolves around the enhancement of solid oxide fuel cell performance, with particular attention directed toward the intricate oxygen reduction reaction transpiring at the cathode electrode. The present investigation embarks upon the exploration of a composite material comprising La1-xSrxMnO3-δ (LSM) and La1-xSrxFeO3-δ (LSF) as prospective cathode materials. However, the achievement of optimal composite cathodes necessitates the application of advanced materials engineering strategies. The principal aim of this comprehensive study is the development of high-performance composite cathodes, achieved through the deposition of thin film counterparts onto scandium-stabilized zirconia (ScSZ) electrolyte substrate employing the precision sputtering technique. The ensuing findings unequivocally unveil the remarkable performance exhibited by this innovative composite cathode configuration, notably manifesting its excellence at an operating temperature as modest as 780 °C. These promising outcomes imbue optimism regarding the prospective utilization of this composite material in advanced energy conversion applications, marking a significant advancement toward the realization of sustainable and efficient energy systems.
