| Research Abstract |
In order to recognize the phenomena at the interfaces of solid electrolyte/electrode, in situ electron holography and in situ electron energy loss spectroscopy have been applied to the interfaces of Pt/YSZ、Pt/GDC, and Ni/GDC, in a vacuum or oxygen atmosphere at high temperatures. Redox reactions have been observed as the shifts of inner potentials and the shifts of white lines of constituent cations. In the Ni/GDC system, the oxidization of Ni starts from 200℃ or less.
