Abstract

Electrochemically catalytic Ag particles in nano-range were in situ incorporated into the 15 μm thick cathode consisting of La _{0 6}Sr_{0 4}Co_{0 2}Fe_{0 8}O_{3 8} and Ce_{0 8}Gd_{0 2}O_{1 9} (GDC) via a citrate infiltration method. The Ag-impregnation route ensures very homogeneous particle dispersion and good adhesion of Ag to the ceramic matrices. The functional cathode was successfully operated on the Ni-cermet-supported (ZrO ₂)_{0 89}(Sc₂O₃)_{0 1}(CeO ₂)_{0 01} electrolyte with a GDC buffer layer under a micro-tubular configuration, producing maximum power density of 1.06 W cm ^-2 (1.43 A cm^-2,0.74 V), 0.98 W cm^-2 (1.78 A cm^-2,0.55 V), and 0.49 Wcm^-2 (1.44 A cm^-2,0.34 V) at 650,600, and 550°C, respectively.
