| Outline of Final Research Achievements |
Aiming at efficient use of the electrode space that is limited by the miniaturization of biofuel cell, we imparted fine structures to enzyme electrode. For the enzyme-immobilized carrier, a polythiophene derivative film prepared by electrochemical polymerization was used. By investigating the film fabrication conditions, we succeeded in producing a structure with hemispherical indentations on the electrode, and a hierarchical structure with submicron-villiform structure and a network structure of nanofibers. The results of this research showed that the enlargement of the surface area and the control of the diffusion of reactants by applying nano- and microstructures is the key to efficient use of the space on the electrode.
