Abstract: 
The rising global demand for energy, combined with environmental concerns linked to conventional energy sources, has spurred interest in sustainable and diverse alternatives. This study focuses on enhancing the efficiency of energy conversion devices, specifically solid oxide fuel cells (SOFCs). While conventional Ni/YSZ cermet anodes show promise for the anode of SOFCs, they face challenges, prompting exploration into alternative materials such as Sr2MMoO6-δ (M= Fe, Co, Ni) perovskites. This work investigates the electro-oxidation of methane on Sr2CoMoO6-δ (SCM) anodes and explores the impact of Pd infiltration as a metallic element together with LaFe0.6Co0.4O3 and as a dopant in LaFe0.58Co0.37Pd0.05O3-δ (LFCP). Experimental results reveal improved performance, reduced polarization resistance, and enhanced catalytic activity in SCM anodes impregnated with LFCP, attributed to the homogeneous dispersion of nanoparticles within the anode structure. The study provides insights into optimizing SOFC anode materials for efficient methane electro-oxidation, with potential applications in clean energy technologies.
