In this study, pure CeO2 and Ce0.85La0.10M0.05O2 (M: Sm3+, Gd3+, Dy3+) solid  electrolytes were synthesized using the sol-gel method and sintered at 1350°C  for 12 h. X-ray diffraction (XRD) was used for crystal structure  characterization of the ceramic solid electrolytes. After sintering, all  prepared solid electrolytes were indexed to be cubic crystal lattices. The  thermal properties of the prepared samples were investigated by  thermogravimetric (TG) and differential thermal analysis (DTA) methods. The  surface properties of the grain structure of the ceramic solid electrolytes  were evaluated by scanning electron microscopy (FE-SEM) confirming the  average grain size of about 1 μm. The electrochemical impedance spectroscopy  technique was used to investigate AC electrical properties of prepared solid  electrolytes. The conductivity values at 750°C of the Ce0.85La0.10Sm0.05O2,  Ce0.85La0.10Gd0.05O2 and Ce0.85La0.10Dy0.05O2 and pure CeO2 were found to be  1.10 × 10−3 S/cm, 3.05 × 10−4 S/cm, 8.85 × 10−4 S/cm and 8.44 × 10−10 S/cm,  respectively. The characterization results showed that the La-Sm co-doped  CeO2 sample can be used as a ceramic electrolyte in intermediate temperature  solid oxide fuel cells (IT-SOFC).
