Outline of Final Research Achievements

Recently, composite SOFC (solid state fuel cells) cathodes between the mixed conducting oxides and electrolyte materials are widely examined due to the expectation of reaction site enhancement on triple phase boundary, However, evaluation of quantitative reactivity at triple phase boundary and the detail analysis of reaction process were not enough examined for the mix conducting cathodes. In this study, pattern electrode formation technologies is established to give a quantitative evaluation of activity at triple phase boundary by controlling of the triple phase boundary length and electrode area. As the results, it was found out that interfacial conductivity of La0.6Sr0.4CoO3-d(LSC) cathode on a CeO2 based oxide ionic conductor depended on the area specific triple phase boundary length below 873K. Additionally, it was also discovered that cathodic reaction sites of LSC cathode on a proton conducting electrolyte were mainly triple phase boundaries.
