| Outline of Final Research Achievements |
Enzymatic biofuel cells are expected to be alternative energy sources in the future. Although the electrochemical conversion of NADH to NAD+ is a key process for enzymatic biofuel cells in order to obtain a greater output for practical use, the direct electro-oxidation of NADH requires an extremely high overpotential, in other words the electrochemical conversion barely takes place. In this study, to promote this electrochemical conversion, an indirect electrochemical oxidation was tried with the assistance of both light irradiation and flavins as redox mediators. Using riboflavin or flavinmononucleotide as a redox mediator, the indirect electrochemical oxidation smoothly took place and was utilized as a photogalvanic cell. In addition, several significant results were obtained about the performance, the cell reactions, and the fabrication of enzymatic biofuel cells.
