Benefits of technology

[0007]However, the existing bio-fuel cell has a problem described below. That is, the enzymes used in the bio-fuel cell include an enzyme that initiates original reaction and reverse reaction concurrently. Thus, in the case where the enzyme initiating the reverse reaction is used, electrolytic time of the fuel is increased and power generation efficiency is lowered. Thus, in the past, an enzyme not initiating the reverse reaction has been developed by inheritable genetic modification or the like. If the enzyme not initiating the reverse reaction is used, electrolytic time of the fuel is able to be decreased and power generation efficiency is able to be improved. However, labor and cost are necessitated in order to realize practical use of such an enzyme.
[0008]Therefore, it is a main object of the present invention to provide an electrolytic method of a fuel capable of inhibiting reverse reaction of an enzyme and improving electrolytic rate.
[0010]In the present invention, since the fuel is electrolyzed in the electrode, reverse reaction of the enzyme is inhibited, and electrolytic rate is improved.

example

[0043]A description will be hereinafter given of effects of the present invention specifically with reference to Example and Comparative example of the present invention. FIG. 2 schematically illustrates a method of in-electrode electrolysis according to Example of the present invention. FIG. 3 schematically illustrates a method of out-of-electrode electrolysis according to Comparative example. In Example, the in-electrode electrolysis (Example) illustrated in FIG. 2 and the out-of-electrode electrolysis (Comparative example) illustrated in FIG. 3 were performed by using an electrode onto which gluconate-5-dehydrogenase (Gn5DH) was immobilized, and fuel electrolytic time was measured. Further, for comparison, similar measurement was performed for an electrode onto which glucose dehydrogenase (GDH) was immobilized.

[0044]In forming each electrode onto which each enzyme was immobilized, first, the following respective solutions (1) to (7) were prepared. In addition, as a buffer solutio...

Abstract

An electrolytic method of a fuel capable of suppressing reverse reaction of an enzyme and improving electrolytic rate is provided. In electrolyzing a fuel such as glucose by using an enzyme / electron mediator obtained by immobilizing an enzyme such as gluconate-5-dehydrogenase, alcohol dehydrogenase, and malate dehydrogenase and an electron mediator onto a porous electrode made of a carbon material, electrode reaction is generated only in the enzyme / electron mediator electrode.

Description

TECHNICAL FIELD[0001]The present invention relates to an electrolytic method of a fuel in a fuel cell. More specifically, the present invention relates to a method of electrolyzing a fuel such as glucose by an electrode onto which an enzyme is immobilized in a bio-fuel cell.BACKGROUND ART[0002]A bio-fuel cell in which an enzyme as a catalyst is immobilized onto at least one of an anode and a cathode is able to efficiently extract electrons from a fuel such as glucose and ethanol incapable of being used with the use of a general industrial catalyst. Thus, the bio-fuel cell attracts attentions as a next generation fuel cell having high capacity and high safety (for example, see Patent documents 1 to 3).[0003]FIG. 8 is a diagram illustrating reaction of an enzyme battery that includes a carbon electrode onto which an enzyme and an electron mediator are immobilized and that uses glucose as a fuel. In the enzyme battery illustrated in FIG. 8, oxidation reaction of glucose proceeds in an ...
