抜粋

In the present study, the Ni-free anode fabricated with 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.
