ELECTRON TRANSFER MEDIATOR MODIFICATION ENZYME ELECTRODE, AND BIOLOGICAL FUEL CELL EQUIPPED WITH THIS

摘要

PROBLEM TO BE SOLVED: To provide an electron transfer mediator modification enzyme electrode capable of obtaining high current density and stable electrode performance by covalent bonding an electron transfer mediator through a specific spacer on the surface of a conductive base material constituting an electrode, and to provide a biological fuel cell equipped with the same.

SOLUTION: In the electron transfer mediator modification enzyme electrode provided with a conductive base material connected with an external circuit, an oxidoreductase capable of transferring electron with the conductive base material, and an electron transfer mediator capable of mediating electron transfer between the conductive base material and the oxidoreductase, the electron transfer mediator is covalent bonded on the surface of the conductive base material through the spacer containing at least a direct-chain structure, and the biological fuel cell is provided with the electron transfer mediator modification enzyme electrode.
