title = "Enhanced performance of the GdBaCo2O5+δ cathode with active Ce0.8Sm0.2O1.9 nanoparticles",
abstract = "Cathodic polarization resistance (Rp) critically limits the performance of intermediate temperature solid oxide fuel cell (IT-SOFC). In this paper, high performance GdBaCo2O5+δ - Ce 0.8Sm0.2O1.9 (GBCO-SDC) nano-composite cathodes were fabricated via an ion-infiltration method and their chemical compatibility, microstructures and electrochemical properties were evaluated. Good chemical compatibility was found between GBCO and SDC components. Active SDC nano-particles (∼40nm) formed continuous ionic-conducting phase on the surface of GBCO backbone, which significantly enhanced the electrocatalytic activity for oxygen reduction reaction. The composite cathode with 3.3mg·cm-2 SDC loading showed encouragingly low polarization resistance values of 0.55Ω·cm2 and 0. 096Ω·cm2 at 500°C and 600°C, respectively, which implies their promising application for cathodes of IT-SOFC.",
