The use of doped ceria as an interlayer in solid oxide fuel cells (SOFCs) is ubiquitous, which provides a better thermal expansion match and prevents the interaction between cathode (e.g. LSCF) and electrolyte (e.g. YSZ). However, the role of ceria interlayer on the cathode phase durability, catalytic activity, and performance stability remains obscure. This is particularly true in nickelate cathodes (e.g. Pr2NiO4). In this talk, the attention will be given to electrochemical properties in both nickelate and LSCF cathodes with various interlayers. The role of interlayer on the cathode stability and activity will be discussed.
