Biofuel cell, method for producing the same, electronic apparatus, enzyme-immobilized electrode, and method for producing the same

摘要

A biofuel cell has a structure in which a cathode and an anode are opposed to each other with a electrolyte layer provided therebetween, at least one of the cathode and the anode including an electrode on which at least one enzyme and at least one electron mediator are immobilized. The concentration of the electron mediator immobilized on the electrode is at least 10 times a Michaelis constant K m of the electron mediator for the enzyme, which is determined by measurement in a solution.
