abstract = {In order to improve the catalytic activity of La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)-Er0.4Bi1.6O3 (ESB) composite cathodes during the oxygen reduction process, electroless silver plating method was applied for surface modification, thus obtaining LSCF-ESB-Ag cathodes. The introduction of Ag significantly reduced the polarization impedance, reaching the lowest value (0.03 Ω·cm2 at 700 ℃) at the Ag loading of 15 wt.%, which is only 27% of that of the LSCF-ESB composite cathode (0.11 Ω·cm2 at 700 ℃). According to the cathodic reaction kinetics, the modification of Ag increased the speed of oxygen surface adsorption, dissociation and charge transfer. The NiO-SDC/SDC/LSCF-ESB-Ag single cell exhibited a peak power density of 535 mW·cm−2 at 700 ℃, when using wet hydrogen as the fuel.}
