Abstract

La₂NiO_4+δ-based oxides, mixed ionic-electronic conductors 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) activity. In this study, La_1.7Ca_0.3Ni_0.75Cu_0.25O_4+δ was investigated as a potential cathode on La_0.9Sr_0.1Ga_0.8Mg_0.2O₃ electrolyte support. Furthermore, La_1.7Ca_0.3Ni_0.75Cu_0.25O_4+δ was examined on thin Ce_0.8Gd_0.2O₂ (GDC) electrolyte with Ni-GDC anode support for intermediate temperature SOFCs (IT-SOFCs). La_1.7Ca_0.3Ni_0.75Cu_0.25O_4-δ cathode with gadolinium doped ceria (GDC) electrolyte and NiO-GDC anode support showed a maximum power density of 0.75 W/cm² in H₂ and lower polarization resistance, Rp (2), in impedance spectroscopy at 700°C.
