摘要

Provided is a fuel cell in which it is possible to prevent elution of nicotinamide adenine dinucleotide and/or a derivative of nicotinamide adenine dinucleotide immobilized on an electrode, and to prevent performance degradation due to elution; and a method for manufacturing the fuel cell. A biofuel cell having a structure in which a positive electrode and a negative electrode face each other interposed by a proton conductor, the biofuel cell configured so that an enzyme is used to extract electrons from a fuel, wherein the negative electrode is configured from an electrode having an inorganic compound and/or carbon having pores sized 2 nm or more and 100 nm or less on the surface, nicotinamide adenine dinucleotide and/or a derivative thereof being immobilized on the carbon and/or the inorganic compound. Carbon particles, a carbon sheet, or carbon fiber is used as the carbon. Biocarbon, Ketjen black, activated carbon, or the like is used as the carbon particles. An enzyme required for the enzyme reaction may also be immobilized on the carbon via a pyrene derivative or the like as required.
