Abstract

In this study, Ba_0.5Sr_0.5Zn_0.2Fe _0.8O_3-δ (BSZF) oxide, synthesized by solid-state reaction method, was modified for the cathode of solid oxide fuel cells. Three kinds of BSZF-based cathodes, pure-BSZF, BSZF-GDC (30 wt% Ce _0.9Gd_0.1O_1.95) and BSZF-GDC-Ag, were investigated using AC impedance spectroscopy. The results demonstrated that the performance of BSZF-GDC-Ag cathode was greatly improved; for example, at 700°C its polarization resistance decreased by 61% in comparison with pure BSZF.
