| Research Abstract |
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.
