抄録

The catalytic activity of the La_0.6Sr_0.4Co_xFe_1-xO_3-δ (x = 0.2) perovskite cathode was significantly improved by introducing Ag. This strongly depends on the particle size of Ag that relates to the synthesis route. The Ag particles in nano-range were in situ incorporated into the La_0.6Sr_0.4Co_0.2Fe_0.8O_3-δ based cathode using a novel infiltration. The functional cathode was successfully operated on the anode-supported cell with a ceria thin-electrolyte resulting in a higher cell output at 500 °C. Durability of the cell was evaluated within a short-term period.
