Abstract
A fuel cell with which in the case where an enzyme is immobilized to at least one of a cathode and an anode, sufficient buffer ability is able to be obtained even at the time of high output operation, ability inherent in the enzyme is able to be sufficiently demonstrated, and which has superior performance is provided. In a bio-fuel cell which has a structure in which a cathode and an anode are opposed to each other with an electrolyte layer containing a buffer substance in between, and in which an enzyme is immobilized to at least one of the cathode and the anode, a compound containing an imidazole ring is contained in the electrolyte layer as a buffer substance, and one or more acids selected from the group consisting of acetic acid, phosphoric acid, and sulfuric acid are further added.
