摘要：

The performance of a solid oxide fuel cell (SOFC) with the configuration, H-2, 3 wt % Pd-loaded FeO\25 mol % Y3+-doped BaCeO3 (BCY25)\Ba0.5Pr0.5CoO3, air, was studied between 350 and 600degreesC. The BCY25 electrolyte showed higher ion conductivities than 8 mol % yttria-stabilized zirconia (YSZ) below 800degreesC and 20 mol % Sm3+-doped ceria (SDC) below 600degreesC, thus having the smallest ohmic resistance loss during cell discharge below 600degreesC among the three electrolytes. The overpotentials of the Pd-loaded FeO anode and the Ba0.5Pr0.5CoO3 cathode at 600degreesC were 25 and 53 mV, respectively, at 200 mA cm(-2), which were less than one-fourth those of a Pt electrode. The resulting peak power density was higher than those obtained for two SOFCs using the YSZ and SDC electrolytes with a Ni-SDC anode and a Sm0.5Sr0.5CoO3 cathode below 600degreesC.
