For example, the surface of the electrode is rendered water repellent by forming a water-repellent agent on the surface of this electrode. Thereby, in the case in which the cathode is formed of an electrode to which an enzyme is immobilized and this electrode has pores inside, a fuel cell that can stably achieve a high current value by optimization of the amount of water contained in the cathode and a manufacturing method thereof are provided.

摘要： To provide a fuel cell that can perform efficient power generation through a simple fuel supply. There is provided a fuel cell that generates electricity through progress of an oxidation-reduction reaction using an enzyme as a catalyst, the fuel cell including at least a fuel-vaporizing layer formed through vaporization of a fuel; an anode to which a vaporized fuel is supplied from the fuel-vaporizing layer; and a cathode connected to the anode in a state in which protons can be conducted. In the fuel cell, since a fuel is supplied to an electrode in a vaporized state, a vaporized fuel is supplied to an inner portion of the electrode and a reaction sufficiently proceeds at the inner surface of the electrode, which can achieve high output due to efficient power generation. Furthermore, even if an enzyme or the like is immobilized on an electrode, the enzyme or the like can be prevented from leaching out into a liquid fuel because a fuel is supplied to the electrode in a vaporized state, which can prevent a decrease in the output caused by leaching out of the enzyme or the like.
