Outline of Final Research Achievements

Enzymatic bio-fuel cells, which employ enzymes as catalysts, generate electricity when enzymes oxidize sugars such as glucose. Conventional bio-fuel cells oxidized glucose to extract two electrons and did not use the remaining gluconic acid. In this study, we obtained enzymes that oxidize gluconic acid, and made bio-fuel cells which have multi-step enzymatic reactions. As a result, we succeeded in doubling the capacity of bio-fuel cells.
