摘要 电极与电解质界面对固体氧化物燃料电池电性能有一定影响。通过干压刻印法构造了具有网格界面的电解质基片,在此基片上构造具有网格状阳极-电解质界面的单电池片NiO-YSZ||YSZ||LSM-YSZ,并进行电化学测试和微观结构分析。结果表明,网格单电池最大功率密度优于传统平单电池,刻痕处的微观结构也更加丰富,具有层次。表明界面优化可以增加阳极与电解质的接触面积,增加三相界面密度,进而提高单电池的电化学性能。

Abstract: The interface between electrode and electrolyte has a certain influence on the electrical performance of solid oxide fuel cells.Yttria stabilized zirconia (YSZ) electrolyte substrate with a grid surface is constructed by the dry-pressing and imprinting method in order to analyze the influence of interface optimization on the cell performance.NiO-YSZ anode is coated onto the grid surface of YSZ electrolyte substrate, and La0.85Sr0.15MnO3±δ(LSM)-YSZ cathode is coated on the other side.The prepared single cell sheet with a mesh anode-electrolyte interface is tested for the electrochemical performance and microstructure analysis by mean of SEM.By comparison with traditional cells, the prepared single cell shows higher maximum power densities under the test temperature, and has richer microstructure in the indentation.It is indicated that the optimization of the anode-electrolyte interface at hundreds of micrometers scale can improve the electrochemical performance of single cell.
Key words:  solid oxides fuel cell    three-phase interfaces    uneven interface    anode    yttria stabilized zirconia
