Outline of Final Research Achievements

This study aimed to develop the technologies for the utilization of oxygen-containing compounds, such as alcohols, as new energy media. The electrochemically-oxidation mechanisms of alcohols under alkaline conditions were elucidated by infrared spectroscopic analyses for the direct supply to anion exchange membrane fuel cells. The IR spectra indicated that the intermediate in methanol oxidation was aldehyde species, HxCHO. 2-propanol was not oxidized to CO or CO2 although the oxidation reaction initiated at a relatively low potential. The spinel-type oxide of Ni(Al0.25Fe0.75)2O4 was fabricated, and its degradation behavior and regeneration treatment were investigated for the application in ethanol steam reforming. It was suggested that spinel-structured nickel-based materials are effective for the catalyst design with the consideration of the regeneration by oxidation treatments.
