摘　　要：通过在钆掺杂的氧化铈(GDC)主电解质层上反应磁控溅射(reactive magnetron sputtering)氧化钇稳定的氧化锆(YSZ)电子阻隔层和钆掺杂的氧化铈(GDC)化学隔层,制备出了电池的复合电解质膜。进行了固体氧化物电池的物相分析、微观结构观察和电化学性能表征。复合膜电池的开路电位和输出功率密度高于GDC电池,复合膜的离子电阻减小,电子电阻增大。GDC/YSZ/GDC复合膜呈现了快离子传导特征。The electron barrier layer of yttria-stabilized zirconia(YSZ) on the main electrolyte layer of gadoliniumdoped ceria(GDC) and the chemical barrier layer of gadolinium-doped cerium oxide(GDC) on YSZ layer were prepared by reactive magnetron sputtering for the tri-layered composite films of solid oxide fuel cells.The phase structure analysis,microstructure observation and electrochemical performance evaluation of the solid oxide fuel cells were carried out.The composite membrane fuel cells depicted higher open circuit voltage and higher output power density than that of the GDC fuel cell.The composite membranes depicted lower ionic resistances and higher electron resistances than that of GDC,respectively.GDC/YSZ/GDC composite electrolyte membrane exhibited fast ion conduction.
