FUEL CELLS, METHODS OF USING FUEL CELLS, CATHODES FOR FUEL, CELLS, ELECTRONIC DEVICES, DEVICES USING ELECTRODE REACTIONS, AND ELECTRODES FOR DEVICES USING ELECTRODE REACTIONS
To provide a fuel cell and a method of using the same, which enable such a reaction environment as to exhibit excellent properties as electrode sufficiently, and to provide a cathode for the fuel cell, a device using an electrode reaction, and an electrode for the device using an electrode reaction. A fuel cell 10 includes an electrolyte solution 7 arranged between a cathode 1 and an anode 5. The cathode 1 includes a porous material made typically of carbon and an immobilized thereon. The fuel cell is so configured as to bring at least part of the cathode 1 into contact with a reactant in a gaseous phase. The cathode 1 preferably further includes an immobilized electron-transfer mediator in addition to the enzyme. The reactant in a gaseous phase can be, for example, air or oxygen.
