Electrolytic method of fuel

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.

1 . An electrolytic method of a fuel in which electrolytic reaction is generated only in an electrode in electrolyzing the fuel by the electrode onto which an enzyme is immobilized. 
     
     
         2 . The electrolytic method of a fuel according to  claim 1 , wherein an enzyme initiating reverse reaction is used as the enzyme. 
     
     
         3 . The electrolytic method of a fuel according to  claim 1 , wherein an electron mediator is immobilized onto the electrode together with the enzyme, and
 ratio between an oxidant and a reductant of the electron mediator is controlled by changing electric potential applied between electrodes.   
     
     
         4 . The electrolytic method of a fuel according to  claim 3 , wherein electric potential higher than half wave electric potential of the electron mediator is applied. 
     
     
         5 . The electrolytic method of a fuel according to  claim 2 , wherein the enzyme is gluconate-5-dehydrogenase, alcohol dehydrogenase, or malate dehydrogenase.
