The present study aims to advance the existing body of research on electrode materials used in electrochemical applications, specifically sustainable energy devices, such as solid oxide fuel cells (SOFs). Synthesis and characterization of the Ce~0.8~Cu~0.1~Co~0.1~MnO~3~ electrocatalyst was performed, followed by analysis of the electrochemical properties of this complex oxide system. The electrocatalyst offers high activity in oxygen reactions at intermediate temperatures, and is considered to be a promising candidate for SOFs that operate in such a range, as it shows significant improvement in catalytic activity. The structural and morphological features of Ce0.8Cu0.1Co0.1MnO3 have been examined using X-ray diffraction, scanning electron microscopy with energy dispersive X-ray spectroscopy, transmission electron microscopy and TEM analysis showed that particle size ranged from 40 nm to 80 nm. Brunauer-Emmett-Teller analysis showed that the calculated surface area of Ce-CCM was 196.1 m2/g, EIS demonstrated that at a temperature of 600 degrees, the current density was 1.1 W/cm2. This is 1.2 times higher than that of existing cathode materials. Further, the oxidation states and surface composition of the Cu and Co incorporated into the CeMnO3 matrix was confirmed through XPS analysis. The results point to the potential of this material being used as an electrocatalyst for efficient oxygen reactions in various energy harvesting devices.
