In this study, we investigate a cobalt-free titanium-doped perovskite oxide with the nominal composition of Ba0.5Sr0.5Fe0.8Cu0.1Ti0.1O3-delta (BSFCuTi) as a potential electrode material for intermediate temperature solid oxide fuel cells (IT-SOFCs). In comparison to Ba0.5Sr0.5Fe0.9Cu0.1O3-delta, BSFCuTi exhibits improved phase stability and a reduced thermal expansion coefficient even though the electrical conductivity decreases. A low area specific resistance of 0.088 Omega cm(2) is achieved at 600 degrees C based on a symmetrical cell test, which is comparable to the result for the benchmark Ba0.5Sr0.5Co0.8Fe0.2O3-delta cobalt-based perovskite electrocatalyst. Stable operation for a period of 200 h is also demonstrated. The I -V test shows a very high power output of 1.16 W cm(-2) for a single cell using a BSFCuTi cathode at 600 degrees C. In addition, the BSFCuTi can be partially reduced under a reducing atmosphere to prepare a suitable anode material. A cell with BSFCuTi as the material for both electrodes and a thick Gd0.2Ce0.8O19 electrolyte (300 mu m) delivers an attractive power density of 480 mW cm(-2) at 800 degrees C. The high activity, favorable stability and bi-functionality make BSFCuTi a promising electrode material for IT-SOFCs. (C) 2015 Elsevier B.V. All rights reserved.
