Research Abstract

Cell performance was measured at 773-1073 K for Ni-GDC(Gd-doped ceria) anode-supported GDC film (60μm thickness) with SrRuO_3 cathode using a 3vol% H_2O-containing H_2 fuel. Reduction of particle size (0.89μm) of SrRuO_3 cathode was effective to decrease the voltage drop at the cathode because of the increased length of triple phase boundary (GDC electrolyte- SrRuO_3 cathode-O_2 gas). The maximum power density using 0.89μm of SrRuO_3 cathode was 113mW/cm^2 at 873 K and 348mW/cm^2 at 1073 K.
