中文摘要：

采用甘氨酸-硝酸盐溶液燃烧法制备了粒度均匀、纯钙钛矿结构的La0.75Sr0.20MnO3-δ（LSM）阴极粉体。研究表明LSM阴极与（ZrO2）0.87（Sc2O3）0.11（Mn2O3）0.02（11ScSZ-2Mn2O3）电解质在1350℃以下时具有良好的化学相容性。以LSM-YSZ（氧化钇稳定氧化锆）为阴极,添加碳黑作造孔剂调节阴极的收缩率和孔隙率,采用干压法,在1250℃下共烧结制备了适宜孔结构和孔隙率的LSM-YSZ阴极支撑11ScSZ-2Mn2O3致密电解质薄膜。这种廉价、方便的干压、低温共烧结制备方法有助于推动阴极支撑型固体氧化物燃料电池（SOFC）的发展。

英文摘要：

La0.75Sr0.20MnO3-δ（LSM） powder with pure perovskite structure and uniform particle size was synthesized by glycine-nitrate solution combustion method. The investigations show that LSM cathode has good chemical compatibility with （ZrO2）0.87（Sc2O3）0.11（Mn2O3）0.02 （11ScSZ-2Mn2O3） electrolyte below 1 350 ℃. By adding carbon black as the pore former, the sintering shrinkage and porosity of LSM-YSZ （yttria stabilized zirconia） can be tailored. Dense 11ScSZ-2Mn2O3 electrolyte thin films supported on LSM-YSZ cathodes with a suitable porosity and pore structure were successfully fabricated by dry press technique and subsequent sintering at 1 250 ℃ . This dry-pressing combined with low-temperature co-sintering method is convenient and cost-effective, which facilitates the development of cathode-supported solid oxide fuel cell （SOFC）.
