FUEL CELL, ITS MANUFACTURING METHOD, ENZYME-IMMOBILIZED ELECTRODE, AND ITS MANUFACTURING METHOD, AS WELL AS ELECTRONIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell and its manufacturing method wherein output is improved by optimization of a negative electrode structure.

SOLUTION: In the fuel cell having a structure in which a positive electrode 2 and a negative electrode 1 are opposed to each other via a proton conductor 3, and of which at least the negative electrode 1 is consisting of an enzyme-immobilized electrode 11, a porous electrode having at least one through-hole 12 or non-through-hole is used as the electrode 11. Enzyme, coenzyme, and an electronic mediator are immobilized on the electrode 11. The diameter of the through-hole 12 or the non-through-hole is set to 1 mm or less, and the spacing of the through-holes or the non-through-holes is set to 2 mm or less.
