Abstract
Double perovskite structure with composition of Sr 2 Mg 1-x Mn x MoO 6 (SMMMO) and Sr 2 Mg 1-x Fe x MoO 6 (SMFMO) for anode materials in solid oxide fuel cell have been synthesized by means of solid state reaction and sol gel method, respectively. Crystal structure of those materials were characterized by X-ray diffraction technique and refined using Rietveld method implemented in the Rietica program and their conductivity were determined by DC conductivity measurement technique. The higher Mn concentration the lower the cell volume of SMMO, whilst for SMFO the higher Fe content the larger the cell. For SMMO the ionic conductivity tends to increase with increased Mn, whilst for SMFMO conductivity decreases as Fe concentration increases.
