    Effects of double columnar structure interlayer film, in which tensile strain were introduced, on cathodic activity of SmCoO3 was investigated. Double columnar film of Pr2NiO4(PNCG)-Sm doped CeO2 (SDC), PrBaCo2O5.5-SDC, Sm0.6Sr0.4CoO3(SSC)- SDC, and La0.6Sr0.4FeO3-SDC were successfully prepared by PLD method and it was found that insertion of PNCG-SDC or SSC-SDC double columnar film decreased the overpotential of SSC cathode. The power density of the cell deposited on Ni-Fe porous metal substrate was higher than 3W/cm2 at 773K and impedance results suggested that the increased power density was explained by decreased cathodic overpotential. Increased diffusivity of oxide ion in double columnar film is effective for expanding reaction area resulting in the increased cathodic performance for oxide ion dissociation.
