摘要： A fuel cell which utilizes the biogenic metabolism to produce a high current density is provided. The fuel cell generates electric power in such a way that the fuel is decomposed stepwise by a plurality of enzymes and those electrons formed by oxidation are transferred to the electrode. The enzymes work such that the enzyme activity of the enzyme involved in decomposition in the early stage is smaller than the sum of the enzyme activities of the enzymes involved in decomposition in the later stage. In the case where a coenzyme is involved, the enzyme activity of the oxidase that oxidizes the coenzyme is greater than the sum of the enzyme activities of the enzymes involved in the formation of the reduced form of the coenzyme, out of the enzymes involved in the stepwise decomposition of the fuel.

摘要： Provided are an enzyme immobilizing method, a fuel cell and an electrode for the fuel cell which employ the enzyme immobilizing method, and a method for manufacturing the fuel cell and the electrode. The enzyme immobilizing method prevents reduction in enzyme activity when the enzyme is immobilized on the electrode, so as to make it possible to obtain a high catalyst current value. In the method for immobilizing an enzyme on the electrode used in the fuel cell, an enzyme variant with at least one amino acid residue being deleted, substituted, added, or inserted in a wild-type amino acid sequences is used as the enzyme, and the enzyme variant increases in activity through heat treatment. The immobilization is performed within a temperature range which makes it possible to increase the activity of the enzyme variant.

A fuel electrode is formed by immobilizing with an immobilizer, on an electrode comprised of, e.g., carbon, an enzyme responsible for decomposing a polysaccharide into monosaccharides, an enzyme responsible for decomposing the monosaccharide formed, a coenzyme (e.g., NAD− or NADP+) which forms a reductant due to the oxidation reaction in the monosaccharide decomposition process, a coenzyme oxidase (e.g., diaphorase) for oxidizing the reductant of the coenzyme (e.g., NADH or NADPH), and an electron mediator (e.g., ACNQ or vitamin K3) for receiving electrons generated due to the oxidation of the coenzyme from the coenzyme oxidase and delivering the electrons to the electrode. The fuel cell comprises the fuel electrode and the air electrode that sandwich an electrolyte layer.

摘要： There are provided a fuel cell and a production method therefor in which one or more types of enzymes or further coenzymes are enclosed in a micro space so that electrons can be efficiently extracted from a fuel such as glucose or the like by an enzyme reaction using the micro space as a reaction field, thereby producing electric energy, and in which the enzyme or further the coenzyme can be easily immobilized on an electrode.Enzymes 13 and 14 and a coenzyme 15 necessary for an enzyme reaction are enclosed in liposome 12, and the liposome 12 is immobilized on a surface of an electrode composed of porous carbon or the like to form an enzyme-immobilized electrode. An antibiotic 16 is bonded to a bimolecular lipid membrane constituting the liposome 12 to form one or more pores 17 permeable to glucose. The enzyme-immobilized electrode is used as, for example, a negative electrode of a biofuel cell.
