Abstract
In this work, double-doped NdBa(Fe,Co,Cu)2O5+δ layered perovskites were prepared by solid state reaction method and comparatively examined. Physicochemical analysis included structural characteristics, linear thermal expansion coefficient, oxygen nonstoichiometry, electrical conductivity, and electrochemical performance of the materials. NdBaCo1.5Cu0.5O5+δ (NBCC2) and NdBaFeCoO5+δ (NBFC) materials exhibited good electrical conductivity and linear thermal expansion coefficient relatively matched to common electrolyte materials. Electrochemical impedance spectroscopy measurements in argon-oxygen mixtures demonstrated promising performance of the synthesized materials as cathode materials for solid-oxide fuel cells. The NBCC2 material showed the lowest polarization resistance of 0.17 (800°C) and 0.67 (700°C) Ω cm2 at P(O2) P−1 = 0.2.
