Abstract:Utilizing rare earth doped ceria in solid oxide cells (SOCs) engineering is indeed a strategy aimed at enhancing the electrochemical devices' durability and activity. Particularly, Gd‐doped ceria (GDC) is actively used for barrier layer and catalytic additives in solid oxide fuel cells (SOFCs). In this study, experiments are conducted with La‐doped CeO2 (LDC), in which the Ce sites are predominantly occupied by La, to prevent the formation of the Ce‐Zr solid solution. This LDC is comparably used as a functiona… Show more
