Abstract:
1. A fuel cell comprising: an enzyme electrode that incorporates a first electroconductive base member, a second electroconductive base member, an oxidoreductase and an electron mediator; and a fuel solution containing nicotinamide adenine dinucleotide as a coenzyme operable to assist the oxidoreductase, wherein the enzyme electrode includes: a first portion in which the oxidoreductase is immobilized on the first electroconductive base member; and a second portion in which the electron mediator is immobilized but the oxidoreductase is not immobilized on the second electroconductive base member, wherein the enzyme electrode includes a plurality of the first portions and a plurality of the second portions, and the first portions and the second portions are alternately gathered into an aggregate.
