Аннотация Intermediate temperature Solid Oxide Fuel Cell (IT-SOFC) shows number of advantages over high temperature SOFCs (HT-SOFCs), which includes smaller thermal mismatch between its components, rapid startup with less energy consumption etc. In the present paper, we are presenting the synthesis of ceria based oxygen ion conductor as an electrolyte for the low temperature SOFC. The bulk Gd0.1Ce0.9O1.95 materials have been prepared using ceramic route. Since sintering of this oxide is a crucial parameter, which affects the micro-structural and electrical properties, the green pellets were sintered at 1400, 1500 and 1600C. The synthesized samples were characterized for their structural, elemental, morphological and electrical properties using XRD, EDAX, SEM and dc conductivity, respectively. The density measurements were done for estimation of porosity before and after sintering.
