Durability of La_0.20Sr_0.25Ca_0.45TiO₃-based SOFC anodes: identifying sources of degradation in Ni and Pt/ceria co-impregnated fuel electrode microstructures

Mechanisms of degradation in SOFC containing Ni/CGO, Ni/CeO2 and Pt/CGO co-impregnated La0.20Sr0.25Ca0.45TiO3 anodes are elucidated during long-term, industrially-relevant testing, using AC impedance spectroscopic and microscopic analyses.
