Outline of Final Research Achievements

IIn this study, we investigated the fabrication of membrane-electrode assembly using proton conductive anodic ZrO2-WO3 or ZrO2-WO3-SiO2 nanofilms, which were developed by us, for intermediate temperature fuel cells operating below ~300 degre C. Hydrogen permeable anode foils have been utilized as a support of the proton conducting nanofilms and several fabrication processes have been proposed and examined. We succeeded to generate power. Further, by modifying the anodizing process to form the proton conducting anodic films, we have increased the proton conductivity by nearly one order of magnitude.
