| Outline of Final Research Achievements |
A totally flexible, sheet-shaped biofuel cell has been developed by stacking a bioanode fabric, a hydrogel sheet containing electrolyte and fuel (fructose), and an O2-diffusion biocathode fabric. The results presented include two strategies to improve the performance of the device. (1) An anode modified with an appropriate CNT dispersion showed higher activity. (2) The gas-diffusion biocathode was improved by optimizing its hydrophobicity. The improved biofuel cell sheet produced a maximum power density of 1.0 mW/cm2 at 0.36 V even when bent. Such a flexible, sheet-shaped power source could be combined in the future with flexible electronic to make wearable devices.
