Abstract

Dense film electrodes of La0.6Sr0.4CoO3 were formed on ceria based solid electrolytes by pulsed laser deposition. The oxygen exchange reaction rate on the surface was evaluated by impedance spectroscopy, and the effect of coexistence of LaSrCoO4 phase on the surface was investigated. The tendency of Sr segregation on the surface of La0.6Sr0.4CoO3 was mitigated by addition of porous LaSrCoO4 layer, which reduced the activation energy of oxygen exchange reaction and enhanced the reaction rate.
