摘要：

10Sc1CeSZ is one of the most important electrolyte materials used for solid oxide fuel cells (SOFCs). A novel solid liquid method (SLM) was adopted for the preparation of 10Sc1CeSZ nanopowder. High-purity, single-phase, homogeneous 10Sc1CeSZ powder was successfully prepared using this method. The resulting powders and ceramic pellets were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). A cubic structure was obtained when the value of the specific surface area (SSA) of the starting material ZrO2 was greater than 60 m(2) g(-1). A conductivity of 0.14 S cm(-1) at 800 C was achieved for the sintered pellets. The performance of the electrolyte-supported cell (ESC) NiO+ GDC/10SclCeSZ /10Sc1CeSZ LSM reached 0.66 W cm(-2) at 0.75 V and 850 degrees C. (C) 2013 Elsevier Ltd and Techna Group S.r.l.
