Long-term stability of infiltrated La0.8Sr0.2CoO3−δ, La0.58Sr0.4Co0.2Fe0.8O3−δ and SmBa0.5Sr0.5Co2.0O5+δ cathodes for low temperature solid oxide fuel cells

Here we report the electrochemical performance and long-term stability of La0.8Sr0.2CoO3−δ (LSC), La0.58Sr0.4Co0.2Fe0.8O3−δ (LSCF) and SmBa0.5Sr0.5Co2.0O5+δ (SBSC) infiltrated (ZrO2) 0.89(Sc2O3) 0.1(CeO2) 0.01 (SSZ) cathodes at low temperatures. At 700 °C, the initial polarization resistance of the infiltrated cathodes increased in following order: SBSC-SSZ (0.054 Ω cm2)
