Solid Oxide Fuel Cells is the most promising fuel cell technology due to their low or zero pollution and high efficiency. On this research, fuel cell was fabricated using solid electrode and electrolyte which had been previously developed. Cell fabrication process started by synthesis of electrolyte LSGM using solid state method. Analysis of X-ray diffraction for LSGM powder showed its structure was cubic and space group Pm3m. LSGM powder was pressed into pelet of 2 cm diameter using a hidraulik press and sintered to temperatur 1450oC. SMMMO as anode and LSF cathode were synthesised sol gel method. Gel was casted on electrolyte surface by tape casting followed by heating and then sintering at temperatur of 1350oC. Analysis of X-ray diffraction for SMMMO and LSF thin layer on pelet electrolyte showed structure of SMMMO was monoclinic with space group P21/n and structure of LSF was orthorhombic with space group Pbnm. Cross section of the cell viewed using SEM showed that there were three layers. Cell performance was tested by burning the cell with LPG fuel in the air and showed a maximum potential value of 450 mV. <br /> <br />
