Alternative perovskite materials as a cathode component for intermediate temperature single-chamber solid oxide fuel cell

This paper exploits the suitability of three perovskite materials Ba0.5Sr0.5Co0.8Fe0.2O3- d (BSCF), GdBaCo2O5+d (GBC) and Ba0.5Sr0.5Mn0.7Fe0.3O3- d (BSMF) as SOFC cathodes in the single-chamber configuration operating at the intermediate temperature range. TG analysis showed high thermal stability d...

description This paper exploits the suitability of three perovskite materials Ba0.5Sr0.5Co0.8Fe0.2O3- d (BSCF), GdBaCo2O5+d (GBC) and Ba0.5Sr0.5Mn0.7Fe0.3O3- d (BSMF) as SOFC cathodes in the single-chamber configuration operating at the intermediate temperature range. TG analysis showed high thermal stability depending on the crystalline phases of the materials. The catalytic activity of these three materials for hydrocarbon conversion was investigated under a realistic feed, i.e. with hydrocarbon, oxygen, water and carbon dioxide. Electrochemical impedance spectroscopy of the various cathodes tested in symmetric cell configuration revealed a B-site dependence of the electrode catalytic activity for oxygen reduction. High temperature (1000 °C) powder reactivity tests over a gadolinium doped-ceria (CGO) and perovskite cathode revealed excellent chemical compatibility of BSMF and CGO. Catalytic tests associated with thermal and structural characterization attest to the suitability of these materials in the single-chamber configuration. © 2010 Elsevier B.V. All rights reserved.
