Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) and gadolinia-doped ceria (GDC) were synthesized via a glycine-nitrate process (GNP). A cubic perovskite of BSCF was observed by X-ray diffraction (XRD) at a calcination temperature above 950 degrees C. An anode-supported solid-oxide fuel cell was constructed from the porous NiO+YSZ as the anode substrate, the yittria-stabilized zirconia (YSZ) as the electrolyte, and the porous BSCF-GDC layer as the cathode with a GDC barrier layer. For the performance test, the maximum power density was 191.3 mW cm(-2) at a temperature of 750 degrees C with H-2 fuel and air at flow rates of 335 and 670 sccm, respectively. According to the AC-impedance data, the charge-transfer resistances of the electrodes were 0.10 and 1.59 Omega cm(2), and the oxygen-reduction and oxygen-ion diffusion resistances were 0.69 and 0.98 Omega cm(2) at 750 and 600 degrees C, respectively. SEM microstructural characterization indicated that the fuel cell as fabricated exhibited good compatibility between cathode and electrolyte layers. (C) 2009 Elsevier B.V. All rights reserved.
