Here we report the electrochemical performance and long-term stability of La0.8Sr0.2O3-delta (Lsq, La0.58Sr0.4Co0.2Fe0.8O3-delta (LSCF) and SmBa0.5Sr0.5Co2.0O5+delta (sBsc) infiltrated (ZrO2) o.89(Sc2O3) (0.1)(CeO2) (0.01) (SSZ) cathodes at low temperatures. At 700 degrees C, the initial polarization resistance of the infiltrated cathodes increased in following order: SBSC-SSZ (0.054 Omega cm(2))
