Abstract

My research group has investigated functional ceramic materials for fuel cells (AFC, PEFC) , environmental chemical sensors,  ceramic phosphors, and so on.  For the fuel cell materials, we have developed highly active oxygen electocatalysts, such as perovskite-, pyrochlore- types oxides, sulfides, nitrides, metal-phthalocyanines, etc.  Electrochemical solid-state gas/ion sensor devices based on highly-ion conductive solid electrolyte thin/thick films and various receptor materials were investigated. 

We apply the EPD technique for fabrication of highly dimensional ordered catalysts  for high performance  oxygen electrode of fuel cells and also apply it for preparation of ceramic thick-films for chemical sensors, and ceramic phosphors.
