The hetero-interface electrode, LaSrCoO4-d on La0.6Sr0.4CoO3-d, was examined by means of impedance analysis and steady state polarization method. The performance of the hetero-interface electrode was higher than those of LaSrCoO4-dγandγLa0.6Sr0.4CoO3-d. This is attributed to the enhancement of oxygen exchange at the hetero interface of LaSrCoO4-dγandγLa0.6Sr0.4CoO3-d.
