| 英文摘要 | phase structure, structure stability, electrical properties and catalytic activity for oxygen reduction reaction of the ba-deficient layered-perovskite oxides laba1-xco2o5+delta (lb1-xco, x = 0.00-0.15) have been studied to determine their viability as cathode material of intermediate-temperature solid oxide fuel cells (it-sofcs). lb1-xco had tetragonal layered-perovskite structure when calcined at 850 degrees c-1050 degrees c in air but transformed into cubic structure at higher temperatures. the lb1-xco oxide exhibited lower electrical conductivities and decreased area-specific resistances (asrs) on the ce0.9gd0.1o1.95 (gdc) electrolyte with higher ba-deficiency content. among the samples, the lb0.90co (x = 0.10) oxide exhibited the best electrochemical performance with asr values of 0.118 omega cm(2) at 600 degrees c and 0.023 omega cm(2) at 700 degrees c respectively, similar to 40% lower than the results of the parent oxide (x = 0), demonstrating its promising application as cathode materials of it-sofcs.
