La0。9 sr0。1 cr0。5 mn0。5O3-δ (LSCM)和Gd0。1 ce0。对9O2-δ (GDC)粉末进行了评价。优化了烧结温度、电极厚度和成分。GDC占比大于70%的阳极初始极化电阻最低。然而，GDC份额超过80%的阳极在加速降解试验中明显降解。降解的原因是GDC相的纳米裂解。结果表明，LSCM具有稳定GDC结构的作用，LSCM-GDC 30:70 wt。考虑到初始性能和稳定性，发现%为最佳组成。
La0. 9Sr0. 1Cr0. 5Mn0. 5O3-δ (LSCM) and Gd0. 1Ce0. 9O2-δ (GDC) powders is evaluated. The sintering temperature, electrode thickness and composition are optimized. The anodes with GDC share over 70% exhibited the lowest initial polarization resistance. However, anodes with share of GDC over 80% significantly degraded in the accelerated degradation test. The reason of the degradation is attributed to the nano-cracking of the GDC phase. It was found out that LSCM stabilizes the GDC structure, and LSCM-GDC 30: 70wt.% was found to be the optimal composition considering the initial performance and stability.
