Biogas is a promising fuel for many clean energy applications and have propitious effect on the environment as well. Hydrocarbon fuels open up new path for the electric power generation technology in replacing conventional combustion devices with renewable sources e.g., biofuel. Active and stable anode nano catalysts are utilized to achieve sufficient advantages for solid oxide fuel cells running on biogas. In this paper, a series of ceria based anodes NixLiyCu(1-x-y)-LDC/ZDC/ZLDC (x=0, 0.2, 0.4, 0.6, 0.8, y=0.2) are synthesized via ball milling route, while nanocatalysts NixLiyCu(1-x-y) (NLC) and LDC/ZDC/ZLDC are prepared by glycerol sol-assisted synthesis and simple co-precipitation method respectively . These nanocatalysts are characterized using x-ray diffraction (XRD) to study its structural properties and thermal analyses are carried out by thermo-gravimertic analysis (TGA) and BET. To study its morphology, scanning electron microscopy is done to calculate its particle size and porosity. The performance of the solid oxide fuel cell with biogas has been studied with a 50% composition of methane. The short term sable performance has been observed without any carbon formation. Key words: ceria, lanthanum, zirconium, anode catalysts, biogas
