FUEL CELL, METHOD FOR PRODUCTION OF FUEL CELL, ELECTRONIC DEVICE, ENZYME-IMMOBILIZED ELECTRODE, BIOSENSOR, BIOREACTOR, ENERGY CONVERSION ELEMENT, AND ENZYMATIC REACTION-UTILIZING APPARATUS

摘要

A fuel cell and a method for manufacturing the same are provided, wherein at least one type of enzyme and coenzyme are confined in a minute space, an enzyme reaction is effected while this space serves as a reaction field and, thereby, electrons can be taken out of the fuel efficiently to generate electrical energy, and immobilization of these enzyme and coenzyme on an electrode can be performed easily. The enzyme and the coenzyme required for an enzyme reaction are encapsulated in a liposome 12, and the resulting liposome 12 is immobilized on the surface of an electrode 11 formed from porous carbon or the like so as to form an enzyme immobilization electrode. A transporter is incorporated in the liposome 12, as necessary. An electron mediator is also immobilized on the surface of the electrode 11. The resulting enzyme immobilization electrode is used as, for example, a negative electrode of a biofuel cell.
