Cu doped perovskites SrFe_0.9‐xCu_xMo_0.1O_3‐δ (SFCM, x = 0‐0.2) are explored as cathodes for IT‐SOFCs. The influence of Cu doping on the property of SFCM series was studied in detail. The oxygen content decreases with the increase of Cu doping amount. SFCM samples are chemically compatible with LSGM electrolyte. However, the TEC values are still a bit higher than that of some common SOFC electrolytes. At 750°C, the R_p values are 0.261, 0.227 and 0.155 Ω·cm² for SFCM0, SFCM0.1, and SFCM0.2. The obtained activation energies for x = 0, 0.1, and 0.2 are 1.01, 0.98, and 0.87 eV, respectively. These results indicate that Cu doping into SrFe_0.9‐xCu_xMo_0.1O_3‐δ has a favorable effect on the electrochemical activity of the materials.

表征SrFe0.9-xCuxMo0.1O3-δ（x = 0、0.1和0.2）作为中温固体氧化物燃料电池的阴极

铜掺杂的钙钛矿SRFE _{0.9- X}的Cu _X沫_0.1 ø _{3- δ}（SFCM，X = 0-0.2）被探索作为阴极为IT-SOFC中。详细研究了Cu掺杂对SFCM系列性能的影响。氧含量随着Cu掺杂量的增加而降低。SFCM样品与LSGM电解质化学相容。但是，TEC值仍比某些常见的SOFC电解质的TEC值高一些。在750°C下，SFCM0，SFCM0.1和SFCM0.2的R _p值为0.261、0.227和0.155Ω ·cm ²。所获得的x的活化能= 0、0.1和0.2分别为1.01、0.98和0.87 eV。这些结果表明，铜掺杂成SRFE _{0.9- X}的Cu _X沫_0.1 ø _{3- δ}对材料的电化学活性具有有利的影响。
