Abstract

The catalytic activity of the La0.6Sr0.4CoxFe1-xO3-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 La0.6Sr0.4Co0.2Fe0.8O3-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.
