摘要

PPROBLEM TO BE SOLVED: To provide a fuel cell capable of increasing its output, and a manufacturing method capable of easily manufacturing such a fuel cell. PSOLUTION: This fuel cell has a structure in which a negative electrode 1 faces a positive electrode 2 through a proton conductor 3, and an enzyme, a coenzyme, and an electron mediator are immobilized in the negative electrode 1. In the negative electrode 1, 2-methyl-1,4-naphthoquinone (VK3) as the electron mediator, NADH as the coenzyme, glucose dehydrogenase as an oxidase, and diaphorase as a coenzyme oxidase are immobilized in the ratios 1.0 (mol) : 0.33-1.0 (mol) : (1.8-3.6)10SP6/SP(U): (0.85-1.7)10SP7/SP(U). Acetone is used as a solvent used when immobilizing the VK3. PCOPYRIGHT: (C)2007,JPO&INPIT
