The investigation of composite cathodes consisting of silver and yttria stabilized bismuth oxide (YSB) for low-temperature honeycomb solid oxide fuel cells with stabilized zirconia as electrolyte was presented. The interfacial polarization resistances of a porous YSN-Ag cathode was about 0.3 ω cm 2 at 600° C. It was found by impedance analysis that the performance of an YSB-Ag composite cathode fired at 850° C for 2 H was severely limited by gas transport due to insufficient porosity.open464
