FUEL CELL AND ITS MANUFACTURING METHOD, ELECTRONIC DEVICE, ENZYME SOLIDIFIED ELECTRODE AND ITS MANUFACTURING METHOD, AND WATER REPELLENT AGENT AND ENZYME SOLIDIFIED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell of which at least either of a cathode and an anode is made of an electrode in which enzyme is solidified and which can stably obtain a high current value if the above electrode has pores inside, and provide its manufacturing method.

SOLUTION: The fuel cell is provided with a structure in which a cathode 2 and an anode 1 are facing each other with an electrolyte layer 3 in-between, and the cathode 2 is made of an electrode in which an oxygen reduction enzyme or the like is solidified and at least a part of a surface of the electrode is water-repellent when the electrode has pores inside. For example, a water-repellent agent is formed on the surface of the electrode to attain a water-repellent property. For the water-repellent agent, a material composed of a water-repellent material such as carbon powder or the like and an organic solvent such as methyl isobutyl ketone which phase separates from water is used.
