Abstract

Pr_0.6Sr_0.4FeO₃ (PSF) and Pr _0.6Sr_0.4Fe_0.8Cu_0.2O₃ (PSFCu) perovskite materials were prepared by glycine nitrate method as a cathode material for intermediate temperature solid oxide fuel cells (IT-SOFC). The prepared PSF and PSFCu materials exhibited typical orthorhombic structure and highly porous morphology with high surface area (43-55 m²/g). Upon the 20% Cu doping on the B-site of the PSF, the electrical conductivity increased from 247 S cm^-1 (PSF cathode) to 298 S cm^-1 and polarization resistance of symmetry cell decreased from 0.21 ω cm ² (PSF cathode) to 0.14 ω cm² as compared to PSF cathode (0.21 ω cm²) at 850 °C. Cu doping in B-site of the perovskite generates the oxide ion vacancies which lead the high effective charge carriers, resulting in the enhanced electrochemical performance of PSFCu cathode.
