抄録

It is necessary to form large reaction surface on electrode substrate of enzymatic bio-fuel cell to improve its power density. In this study, a porous carbon layer made of Ketjenblack (KB) was introduced into the enzyme immobilization electrode of a bio-fuel cell, and the effect of KB loading on the enhancement of electrode area and reaction promotion was evaluated based on cyclic voltammetry (CV) measurement. Furthermore, the operation test of the bio-fuel cell was also performed and the impact of addition of porous carbon layer on the cell performance was investigated. It was found that the introduction of porous carbon layer into enzymatic electrode of bio-fuel cell enlarges actual reaction surface and improves limiting current density. The formation of large cracks in the porous carbon layer has a small influence on the cell performance.
