Abstract

A fuel cell capable of directly abstracting electric power from polysaccharides, such as starch. Fuel electrode (1) is produced by fixing on electrode of carbon, etc. (11) by means of a fixative an enzyme participating in decomposition of polysaccharides to monosaccharides, an enzyme participating in decomposition of formed monosaccharides, a coenzyme (e.g., NAD<+>, NADP<+>, etc.) whose reduced form is produced in accordance with an oxidation reaction during the process of monosaccharide decomposition, a coenzyme oxidase (e.g., diaphorase) capable of oxidizing the reduced form of coenzyme (e.g., NADH, NADPH, etc.), and an electron mediator (e.g., ACNQ, vitamin K3, etc.) capable of receiving electrons generated by the coenzyme oxidation from the coenzyme oxidase and delivering the same to the electrode (11). The fuel electrode (1) is disposed opposite to air electrode (5) through electrolyte layer (3) to thereby construct a fuel cell.

Description

technical field

[0001] The present invention relates to fuel cells, electronic devices, movable bodies, power generation systems, and combined heat and power systems using enzymes as catalysts. Background technique

[0002] A fuel cell basically consists of a fuel electrode (negative electrode), an oxidant electrode or an air electrode (positive electrode), and an electrolyte (proton conductor), and has a working principle based on the reverse reaction of electrolyzing water so that hydrogen and oxygen react to form water (H 2 O) and generate electricity. Specifically, the fuel (hydrogen) supplied to the fuel electrode is oxidized and decomposed into electrons and protons (H + ), and the electrons go to the fuel electrode, while the protons H + Move through the electrolyte to the oxidant electrode. At the oxidant electrode, the proton H + Reacts with oxygen supplied from the outside and electrons supplied from the fuel electrode through an external circuit to generate H ...
