摘要：

The preparation of high-quality yttria-stabilized zirconia (YSZ) electrolyte films on porous substrates is critical to the fabrication of high-performance solid-state ionic devices such as solid oxide fuel cells (SOFCs) and gas sensors. In this paper, stable, fully dispersed YSZ suspensions were prepared. Particles zeta-potential and relative viscosity of suspensions were investigated. Thin YSZ films were deposited on NiO-YSZ anode supports with the YSZ Suspensions and then heated to 1400degreesC in air. Dense and crack-free films were obtained with thickness in the range of 20-30 muM. La0.8Sr0.2MnO3 (LSM) paste was printed on the YSZ electrolyte/anode to assemble single fuel cell and tested in the temperature range of 650-800degreesC. The open circuit voltage (OCV) of the cells reached 0.98 V and maximum power density 190 mW/cm(2) at 800degreesC, showing a reasonable performance. The deposited thin films could be considered forelectrolyte application in intermediate temperature SOFCs. (C) 2004 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
