<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of simply supplying fuel and efficiently generating electricity. <P>SOLUTION: The fuel cell generates electricity by the progress of an oxidation-reduction reaction with an enzyme as a catalyst. The fuel cell includes at least a fuel vaporization layer formed by vaporizing fuel, a negative electrode to which the vaporized fuel is supplied from the fuel vaporization layer, and a positive electrode connected to the negative electrode in a proton conductible state. Since the fuel cell supplies fuel in a vaporized state to an electrode, the vaporized fuel is supplied into the electrode, the reaction on the inner surface of the electrode fully progresses, and thus higher output can be obtained by efficient generation of electricity. Since the fuel is supplied in the vaporized state to the electrode even when enzyme or the like is fixed to the electrode, the enzyme or the like can be prevented from being eluted into liquid fuel, and a reduction in output due to the elution of the enzyme or the like can be prevented. <P>COPYRIGHT: (C)2009,JPO&INPIT |
