摘要：
A 10 mol%Sc2O3, 1 mol%CeO2 stabilized-ZrO2 (SSZ) powder was successfully prepared using the sol gel method. Subsequent SSZ electrolyte pellets were prepared by tape casting technique and sintered at 1400 degrees C, 1450 degrees C, 1500 degrees C, 1550 degrees C and 1600 degrees C. These were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). SSZ showed a pure cubic phase after sintering, the grain size of SSZ increased with the increase of sintering temperature. The SSZ sintered at 1550 degrees C showed the highest ion conductivity. The maximum power densities of Ni-SSZ/SSZ/La0.8Sr0.2MnO3-delta (LSM)-SSZ single cells sintered at 1550 degrees C were 0.18, 0.36, 0.51 and 0.72 W cm(-2) at 650, 700, 750 and 800 degrees C, respectively. The polarization resistance (R-p) of the single cell attained 0.201 Omega cm(2) at 800 degrees C. (C) 2016 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
