中文摘要：

制备了复合阴极材料NdB％5Sr0.5C0.2O5＋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0．134n·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382mW·cm-2．

英文摘要：

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 ℃.
