摘要：
In this work, a nano-sized samaria-doped ceria(SDC) was prepared by a urea-based hydrothermal method and characterized by XRD, FESEM and TEM. It was observed that the increase in synthesis time and temperature gave rise to crystallity and particles size. Moreover, the synthesised powders had a excellent ion-conductivity(0.1 S/cm at 600 similar to 800 degrees C) which is suitable for electrolyte of intermediate temperature-solid oxide fuel cell(IT-SOFC). Sub-sequently for use as electrolyte for anode-supported IT-SOFC, we tried to deposit the SDC powder on a porous NiO-SDC substrate by electrophoretic deposition(EPD) method. From the FESEM observation, a compact and gas-tight SDC thin film was obtained when using acetone solvent with constant voltage of 20 V for 10 s.
