摘要:
采用甘氨酸-硝酸盐法(GNP)制备Pr0.6Sr0.4CoO3-δ-xCe0.8Sm0.2O1.9(PSC-xSDC,10%≤x≤40%)复合阴极材料,研究PSC-xSDC的电性能、电化学性能、热膨胀性能。结果表明:PSC、SDC之间的化学相容性良好。PSC-xSDC复合阴极材料的电导率在600~800 ℃中温范围内均远高于100 S/cm,PSC-xSDC中SDC最佳复合量为30%,1 000 ℃煅烧的PSC-30%SDC复合阴极材料与电解质接触良好,在750 ℃测得的界面极化电阻为0.054 Ω·cm2。PSC与SDC复合适当降低了阴极材料的热膨胀系数,PSC-30%SDC的热膨胀系数为16.77×10-6 K-1
Abstract:
Pr0.6Sr0.4CoO3-δ-xCe0.8Sm0.2O1.9 (PSC-xSDC,10%≤x≤40%)were synthesized by the glycine-nitrate process(GNP). Performance of electrochemical, electrical conductivity and thermal expansion for PSC-xSDC cathode materials were investigated. Results showed that PSC had good chemical compatibility with SDC. The corresponding electrical conductivities of PSC-xSDC were more than 100 S/cm in the intermediate temperature range of 600~800 ℃. In the series of PSC-xSDC composite cathodes, the PSC-30%SDC cathode calcined at 1 000 ℃ exhibited good contact with SDC and the lowest polarization resistance(0.054 Ω·cm2) at 750 ℃. The thermal expansion coefficient of PSC-30%SDC composite cathode was reduced to 16.77×10-6 K-1.
