Construction of a multi-stacked sheet-type enzymatic biofuel cell

Abstract

We have constructed a sheet-type glucose/dioxygen enzymatic biofuel cell with multi-stacked structure, in which one biocathode is sandwiched with two bioanodes in parallel. The energy density of the biofuel cell reached 14.1 mWhcm-3. The cell has achieved the acceptable performance on re-fueling, and the stability of the cell before use was drastically improved by adding raffinose. © The Electrochemical Society of Japan, All rights reserved.
