Image analysis and quantification were performed on porous scaffolds for building SOFC cathodes using the two types of YSZ powders. The two powders (U1 and U2) showed different particle size distribution and sinterability at 1300 °C. AC impedance on symmetrical cells was used to evaluate the performance of the electrode impregnated with 35-wt.% La_0.8Sr_0.2FeO₃. For example, at 700 °C, the electrode from U2 powder shows a polarization resistance (R_p) of 0.21 Ω cm², and series resistance (R_s) of 8.5 Ω cm² for an YSZ electrolyte of 2-mm thickness, lower than the electrode from U1 powder (0.25 Ω cm² for R_p and 10 Ω cm² for R_s) does. The quantitative study on image of the sintered scaffold indicates that U2 powder is better at producing architecture of high porosity or long triple phase boundary (TPB), which is attributed as the reason for the higher performance of the LSF-impregnated electrode.

使用两种类型的YSZ粉末在用于构建SOFC阴极的多孔支架上进行图像分析和量化。两种粉末（U1和U2）在1300°C时显示出不同的粒度分布和可烧结性。对称电池上的交流阻抗用于评估浸有35 wt％La _0.8 Sr _0.2 FeO ₃的电极的性能。例如，在700°C下，对于厚度小于2 mm的YSZ电解质，U2粉末电极的极化电阻（R _p）为0.21Ωcm ²，串联电阻（R _s）为8.5Ωcm ²。比来自U1粉末的电极（R的电极为0.25Ωcm ²_p和10Ωcm ^2（对于R _s）而言。烧结支架图像的定量研究表明，U2粉末在产生高孔隙率或长三相边界（TPB）的体系结构方面表现更好，这归因于LSF浸渍电极性能更高的原因。
