摘要： A water-in-oil (W/O) emulsion which is stable even with a high water content is provided. The water-in-oil (W/O) emulsion is obtained by a three-phase emulsification using a reverse vesicle of an amphiphilic compound as an emulsifier. As the amphiphilic compound, a sucrose fatty acid ester is preferable, and a sucrose fatty acid ester with an HLB value of 6-12 is more preferable. The reverse vesicle can be prepared by mixing an amphiphilic compound with a non-polar solvent. The water-in-oil (W/O) emulsion can be formed by using the prepared mixture containing the reverse vesicle as an oil phase and adding water thereto for emulsification. As the non-polar solvent, an alicyclic hydrocarbon solvent such as cyclohexane is preferable. The reverse vesicle preferably has a particle diameter of not more than 1 μm.

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.
