Abstract

The hetero-interface electrode, LaSrCoO_4-δ on La _0.6Sr_0.4CoO_3-δ, was examined by impedance analysis and steady state polarization method. The performance of the hetero-interface electrode was higher than those of LaSrCoO_4-δ and La_0.6Sr_0.4CoO_3-δ. This is attributed to the enhancement of oxygen exchange at the heterointerface of LaSrCoO _4-δ and La_0.6Sr_0.4CoO _3-δ.
