摘要： 用一种廉价的湿化学方法 ,在Ni_YSZ阳极基膜上制备出致密的YttriaStabilizedZirconia(YSZ)薄膜 .薄膜的厚度约为 10 μm ,致密均匀 ,无裂纹等缺陷 .以Ni_YSZ阳极基膜 ,YSZ薄膜和锶掺杂锰酸镧阴极 (LSM )组装的SOFC单电池 ,在 80 0℃下功率密度达 0 1W /cm2 .研究分析表明 ,YSZ薄膜的IR降 (包括电极 /YSZ薄膜的接触电阻 )较小 ,不是影响电池性能的主要因素 ,大的阳极过电位是影响电池性能的主要因素 .

Abstract: By using a cost_effective wet process,dense yttria stabilized zirconia (YSZ) films on Ni_YSZ anode substrates have been prepared successfully.The YSZ film was characterized to be around 10 μm in thickness,sufficiently dense,uniform and crack free.A single solid oxide fuel cell fabricated from the supported YSZ film electrolyte on the anode substrate and a LSM cathode prepared on the YSZ film was tested.The power density reached to 0.1 W/cm 2 at 800 ℃,showing a reasonable performance.Further analysis on both electrodes shows that the anodic overpotential was much larger than IR drop (including YSZ resistance and contact resistance) and than the cathodic overpotential.The performance of the cell was limited by the anodic overpotential.

Key words: Reduced temperature solid oxide fuel cell, Yttria stabilized zirconia, Film preparation
