摘要:
A dense and uniform 3 mol% yttria-stabilized tetragonal zirconia polycrystal (3YSZ) electrolyte film of 6 mu m in thickness was fabricated by slurry spin coating on a porous NiO/3YSZanode substrate. Composite cathodes of La0.7Sr0.3MnO3 impregnated with Sm0.2Ce0.8O1.9 were fabricated on the 3YSZ films. A single cell produced in this way was tested at 700, 750 and 800 degrees C with hydrogen as fuel and stationary air as oxidant. Test results revealed an open-circuit voltage of 1.04V at 800 degrees C, and maximum power density of 551.895 and 1143 mW cm(-2) at 700,750 and 800 degrees C, respectively. Impedance spectra results demonstrated that the cell performance was determined by the polarization resistance of the cathode. (c) 2008 Elsevier B.V. All rights reserved.
