In the present study, the doctor blade method is employed to fabricate thin film electrolytes applied to the solid oxide fuel cell (SOFC). Yttria Stabilized Zirconia (YSZ) is adopted for the electrolyte thin films. The electric property of the YSZ thin films fabricated under various sintering conditions are compared in terms of the ion conductivities. The relation between the grain size, sintering time, sintering temperature and the ion conductivity are discussed in detail to evaluate the electric property of electrolyte. Then, a single solid oxide fuel cell is made experimentally, and the current-voltage relation and the power density of SOFC is investigated. Finally, it is shown that the present SOFC of YSZ electrolyte proved to be good performance of power density 163mW/cm~(2).
