ABSTRACT

La2NiO4 + δ based oxides, a mixed electronic-ionic conductors (MIECs) with K2NiF4 type structure, have been considerably investigated in recent decades as electrode materials for advanced solid oxide fuel cells (SOFCs) due to their high electrical conductivity, and oxidation reduction reaction (ORR). In this study, structure properties of La(Ca)2Ni(Cu)O4 + δ were studied as a potential cathode for intermediate temperature SOFCs (IT-SOFCs).
