摘　　要：利用一步甘氨酸燃烧法制备40Pr0.6Sr0.4FeO3-δ–60Ce0.9Pr0.1O2-δ(PSFO–CPO)复合阴极材料,并对其基本物理性质进行了研究。XRD结果表明,在950℃烧结10 h后形成了PSFO–CPO复合相。样品的电导率在850℃时达到最大值为0.68 S·cm-1。对40Pr0.6Sr0.4FeO3–60Ce0.9Pr0.1O2-δ进行了阻抗性能测试,在800℃时,阻抗值为0.049Ω·cm2。进行了单电池的性能测试,800℃时的功率为117 mW/cm2。This paper studies using single-step glycine combustion method to prepare 40Pr0. 6Sr0. 4FeO3-δ– 60Ce0. 9Pr0. 1O2-δ( PSFO-CPO) composite cathode material,and the fundamental physical properties. The XRD results show that the PSFO-CPO composite is formed after being sintered at 950 ℃ for 10 hours. The electrical conductivity of samples reaches the maximum value 0. 68 S·cm-1at 850 ℃. It tests the impedance performance of 40Pr0. 6Sr0. 4FeO3-δ– 60Ce0. 9Pr0. 1O2-δ-at 800℃ the impedance value is 0. 049Ω·cm2,and tests performance of single battery-power is 117 mW / cm2at 800 ℃.
