LSCF-Ag Composite Cathode for Reduced-temperature SOFCs

Operating temperature is high and long start-up time, and there is a problem of the material deterioration etc. The electrode development to obtain the catalyst revitalization even at the low temperature is advanced now. We attracted to attention because of Ag is high the electron conductivity in the metal and the oxide ion conductivity. In this study, to improve the performance, we impregnated Ag particles in the LSCF-GDC cathode using Ag(NO)3. These new cells showed the high cell performance.
