摘要：

Dense, crack-free, similar to 7.5 mu m thick, 8 mol% yttria stabilized zirconia (YSZ) film was aerosol deposited on porous NiO-YSZ anode substrates at room temperature without additional high-temperature sintering. The films' microstructures and gas permeability were observed after annealing at various temperatures. The dense, gas-tight film that was observed up to 1000 degrees C became porous at higher temperatures probably due to structural instability related to oxygen non-stoichiometry. A cell using such film as electrolyte showed an open cell voltage of 1.10 V and a maximum power density of 0.51 W/cm(2) at 750 degrees C. (c) 2012 Elsevier Ltd. All rights reserved.
