The La{sub 0.5}Sr{sub 0.5}MnO{sub 3} (SLM)-8 mol % yttria stabilized cubic zirconia (YSZ) composite films were deposited on YSZ and {alpha}-alumina tablets by a sputtering technique. The films with various SLM/YSZ ratios were deposited by applying electric power to SLM and YSZ targets independently. The electrical conductivity and oxygen reduction overpotential of the films were measured. The electrical conductivity of the sputtered films was adequate for cathode in planar SOFC. The cathodic over-potential extremely decreased with the addition of YSZ to SLM.
