Abstract:
PROBLEM TO BE SOLVED: To provide a technique for increasing an output of a microbial fuel cell.SOLUTION: There is provided a microbial fuel cell using a polyol, such as glycerol, as fuel, and microbes, in which an enzyme catalyzing an oxidation-reduction reaction is introduced by genetic modification, on the negative electrode side. In the microbial fuel cell, a high output can be obtained by maintaining the microbes, in which an enzyme, such as diaphorase, catalyzing an oxidation-reduction reaction is introduced by genetic modification, on the negative electrode side, thereby accelerating a rate of the reaction.
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell capable of suppressing insects from swarming around in the case of the leakage of a fuel solution. SOLUTION: The fuel cell has a living thing repelling performance by vegetable essential oil and/or its component. The living thing repelling performance by the vegetable essential oil can be obtained by including the vegetable essential oil in fuel or by being applied to at least a part of the case. In the fuel cell, it possible to effectively suppress insects from swarming around on the fuel solution by the living thing repelling performance of the vegetable essential oil even if a compound which can be a biological nutrient is used as a fuel and such a fuel solution causes leakage.

Abstract:
PROBLEM TO BE SOLVED: To provide a fuel cell that can make improvement of electric current density and its maintenance factor in the case where at least an enzyme and an electronic mediator are immobilized to at least one of a cathode and an anode by a polyion complex consisting of poly-L-lycine and sodium polyacrylate. SOLUTION: In a fuel cell having construction in which the cathode 2 and the anode 1 are opposed each other via an electrolyte layer 3, the cathode 2 and/or the anode 1 are provided with at least an enzyme and an electronic mediator immobilized on the electrode/electrodes by a polyion complex consisting of poly-L-lycine and sodium polyacrylate, a ratio of mass of poly-L-lycine and sodium polyacrylate in the polyion complex is 1:0.01-1.0. The mass of the poly-L-lycine is, for example, ≥7.1×10 -3 mg/mm 2 and ≤3.6×10 -2 mg/mm 2 . COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a biofuel battery and a power supply device capable of replenishing a battery main body with fuel without using a fuel cartridge.SOLUTION: A fuel supplying part consisting of, for example, a beehive base or a beehive plate for honey bees, is provided on one surface of a power generation part having electrodes (an anode and a cathode) on whose surfaces a redox enzyme exists, and collection and/or modification of fuel is performed by organisms such as honey bees. At this time, if needed, filter materials such as a nonwoven fabric and a cellophane are arranged between the anode and the beehive base or the beehive plate to supply the honey to the anode via these filter materials.
