摘要：
Ba0.9Co0.7Fe0.2Nb0.1O3 (- delta) (BCFN) perovskite material was synthesized and evaluated as cathode for La0.8Sr0.2Ga0.83Mg0.17O3 (- delta) (LSGM) electrolyte supported intermediate temperature solid oxide fuel cells (IT-SOFCs). X-ray diffraction results showed that BCFN was chemically compatible with the LSGM electrolyte. Maximum power densities of 0.36, 0.57, 0.80 and 1.1 W/cm(2) were obtained for LSGM electrolyte supported cells with BCFN as cathode and Ni-GDC as anode operated at 650, 700, 750 and 800 degrees C, respectively. Further, the cell performance was stable under a constant current of 0.6 A/cm(2) for over 204 h at 750 degrees C. (C) 2011 Elsevier B.V. All rights reserved.
