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.
