中文摘要：

采用硝酸盐-甘氨酸溶液燃烧法合成了（ZrO2）0.87（Sc2O3）0.11（Mn2O3）0.02（11ScSZ-2Mn2O3）粉体,通过X射线衍射仪（XRD）、透射电镜（TEM）、场发射扫描电镜（FESEM）及氮气吸附等手段对粉体进行表征。结果表明,所合成的11ScSZ-2Mn2O3粉体具有单一立方结构,比表面积达28.6m^2/g,粒度均匀。非等温和等温烧结测试均表明该粉体具有良好的烧结活性,可在1200℃下烧结致密化。以11ScSZ-2Mn2O3粉体为原料配制电解质粉体浆料,采用浸渍-提拉法在NiO-氧化钇稳定氧化锆（YSZ）阳极基体上制备了电解质薄膜,在1250℃下实现了负载型薄膜的烧结致密化,与La0.6Sr0.4Co0.2Fe0.8O3-δ（LSCF）阴极组装了单元电池Ni-YSZ/11ScSZ-2Mn2O3/LSCF。该单元电池在中温下以H2为燃料表现出良好的电性能输出,在操作温度为650℃和700℃下的最大输出功率密度分别为0.55W/cm^2和0.90W/cm^2。

英文摘要：

（ZrO2）0.87 （Sc2O3）0.11 （Mn2O3）0.02 （11ScSZ-2Mn2O3） powder was synthesized by a nitrate-glycine solution combustion route.The properties of 11ScSZ-2Mn2O3 powder were characterized by X-ray diffractometer （XRD）,transmission electron microscopy （TEM）,field-emission scanning electron microscopy （FESEM） and nitrogen adsorption method.The results show that 11ScSZ-2Mn2O3 powder is in the pure cubic structure with a specific surface area of 28.6 m^2/g and uniform particle size distribution.The results of non-isothermal and isothermal sintering tests suggests that 11ScSZ-2Mn2O3 powder possesses high sintering activity and can be fully sintered below 1 200 ℃.NiO-YSZ （YSZ：yttria stabilized zirconia） anode-supported dense 11ScSZ-2Mn2O3 electrolyte film was prepared by dip-coating method and then sintered at 1 250 ℃ for 4 h.With La0.6Sr0.4Co0.2Fe0.8O3-δ（LSCF） as the cathode,the single cell Ni-YSZ/11ScSZ-2Mn2O3/LSCF was constructed.The cell demonstrated excellent generation performance with the maximum power densities of about 0.55 and 0.90 W/cm^2 under operation at 650 ℃and 700 ℃,respectively.
