| Research Abstract |
Conventional microstructures in anode of solid-oxide fuel cells has not been necessarily optimized in a view point of the transfer of matters or chemical reactions at their boundaries because the paths are located randomly. In this study, we aimed for alignment of YSZ, Ni and pore along the thickness direction, in which the oxygen ions, electrons and gases are effectively transferred respectively. Ni particles were aligned by magnetic field and the maximum power improved to 1.6 times as the conventional cell. The reconstruction of the microstructure with FIB-SEM and electrochemical reaction calculation indicated that the tortuosity was improved to about 3 from 7. Furthermore, Al film was deposited on a Zr substrate and alumina through nanoholes were formed by anodic oxidation, and then the zirconia pillars were successfully synthesized by reanodization using the nanoholes as a mold.
