摘要 制备了复合阴极材料NdBa0.5Sr0.5Co2O5+δ-40%Ce0.9Gd0.1O1.95(NBSC-40%GDC).NBSC-40%GDC的平均热膨胀系数(TEC)为16.0×10-6K-1,其在700℃时极化电阻仅为0.134Ω.cm2.进行了以电解质为支撑体的单电池(NBSC-40%GDC/LSGM/NiO-GDC)的性能测试,在800℃时,功率密度达到382 mW.cm-2. Composite cathode material NdBa0.5 Sr0.5 Co2 O5＋δ-40% Ce0.9 Gd0.1 O1.95 （ NBSC-40% GDC ） was investigated. The average TEC values was 16.0 × 10 ^-6 K-1. The polarization resistance was as low as 0. 134 Ω · cm2 at 700 ℃. The electrolyte-supported fuel cell （NBSC-40% GDC/LSGM/NiO-GDC ） generated good performance with the maximum power density of 382 mW · cm-2 at 800 ℃.
