摘要：

Effect of NiO/YSZ compositions on the co-sintering process of anode-supported fuel cell was researched. The green YSZ layer was fabricated by modifying electrostatic powder coating, and the relative density is about 52%. After co-firing at 1400 degrees C for 5h, the sample of YSZ film based on the 1000-NY support (pre-calcinated NiO 60wt.%, YSZ 40wt.%) is concave due to the mismatch of shrinkages between the YSZ film and anode support and there exist cracks on the film. Dense YSZ films based on the NY-20P (NiO 48wt.%, YSZ 32wt.% and graphite 20wt.%) support were fabricated after co-firing at 1400 degrees C for 2h. The OCV and the peak power density of a single cell with a 15 mu m thick YSZ film based on the NY-20P support are 1.09 V and 315 mW/cm(2) at 800 degrees C, respectively. (c) 2005 Elsevier B.V.
