Performance of a compact cell stack of thin film solid oxide fuel cell (SOFC) using yttria-stabilized zirconia (YSZ) electrolyte films between 7 μm and 9 μm thick grown by RF magnetron sputtering was studied to power generation property at intermediate temperatures from 700 to 900°C. The series connected SOFC using YSZ film of 7 to 9 μm thick showed a stable generation property at intermediated temperature of 700°C. Moreover, the V-I property of series connected SOFC using YSZ film of 9 μm thick obtained higher than that of the cell prepared with YSZ film of 7 μm thick. As the result, it was found that series connection of two cells could improve the cell performance, and a compact cell stack of thin film SOFC could be operable at intermediate temperatures.
