SOFC electrode with the bi-layered structures were prepared with electrophoretic deposition (EPD) methods. The thicknesses of each layer were well controlled with the deposition time and applied voltage in the EPD process. The bi-layered structures exhibited the lowered cathodic potential loss compared to the mono-layered ones. The decrease in thickness of the first layer and the increase in that of the second layer effectively reduced both polarization and ohmic resistances. Bilayer structures consisting of active and current collecting layers were fabricated. The examined bi-layered structures, LSM/LSM-YSZ, exhibited the minimal polarization resistance when the thicknesses were 10 and 4 micrometers at 600^oC, respectively. It was deduced that the effective thickness of the active layer is around 4 mm under the current condition. We also prepared layered anode films by EPD method. The layered structure of anodes formed by EPD were also effective to reduce electrode over-potential.
