摘要:

采用溅射或溅射与退火相结合的方法制备了一系列氧化钆掺杂的氧化铈(GDC)隔层,并考察了其对固体氧化燃料电池性能的影响. 结果表明,200 ℃下溅射获得了立方结构氧化钆掺杂的氧化铈均匀薄膜,在900-1100 ℃范围内的退火处理使得GDC薄膜致密,从而有效阻止了氧化钇掺杂的氧化锆电解质与阴极材料之间的反应,大幅度提高了电池的电化学性能.

Abstract:

We prepared gadolinia-doped ceria (GDC) barrier layers by sputtering and annealing at various temperatures. We then investigated the effects of the GDC barrier layers on the performance of anode-supported solid oxide fuel cells. Sputtering at 200 ℃ readily produced a uniform, thin layer of cubic GDC. Sputtering and annealing at 900-1100 ℃ formed uniform, thin, dense films, which effectively prevented the reaction between the yttria-stabilized zirconia electrolyte and the Ba0.5Sr0.5Co0.8Fe0.2O3-δ cathode. The single cells assembled with the thin, dense GDC barrier layers sputtered at 200 ℃ and annealed at 900-1000 ℃ exhibited excellent electrochemical performance.
