The hetero-interface between cathode(or anode)/doped ceria electrolyte was characterized by using analytical TEM. The equal length diffusion of components of electrodes and electrolyte which was named as ‘mutual diffusion’ was observed. This equal length diffusion of components of electrodes and electrolyte through the interface made the super-structure which is difference from matrix. The formation of super-structure by mutual diffusion would decrease the performance of solid oxide fuel cell below 500°C. To enhance the performance of solid oxide fuel cells which operation temperature is below 500°C, it is found that the design of hetero- interface which consists of the active metal-oxygen vacancy-CeOx clusters is important.

利用分析型透射电镜对阴极（或阳极）/掺杂氧化铈电解质之间的异质界面进行了表征。观察到电极和电解液组分的等长扩散，称之为“互扩散”。电极和电解液组分通过界面等长扩散，形成了不同于基体的超结构。在500°C以下，由于相互扩散形成的超结构会降低固体氧化物燃料电池的性能。为了提高工作温度低于500°C的固体氧化物燃料电池的性能，发现由活性金属-氧空位-CeOx团簇组成的异质界面的设计是重要的。
