Outline of Final Research Achievements

The important results which were obtained by the present work are summarized as follows; It was clarified that oxygen defect structure with C type rare earth structure was formed in the anodic condition, although the formation of aforementioned oxygen defect structure was not so important for development of high temperature operation solid oxide fuel cells. In the present work, a development of high quality electrode which includes active metal/ defect fluorite interface was performed in order to design the functional interface which can promote the fuel cell reaction below 100 degree C. This challenge tells us that Pt-defect fluorite interface with C type rare earth structure has promotion effect in the fuel cell reaction. On the basis of all experimental results, we successfully fabricated the functional interface by doping small amount Pt cation in the anode layer of solid oxide fuel cells and hydrogen electrode of solid oxide electrolysis cells.
