<P>PROBLEM TO BE SOLVED: To provide a fuel cell that, when an enzyme is immobilized on at least one of a positive electrode and a negative electrode, can obtain satisfactory buffering capability even during high-output operation, can satisfactorily exhibit capability inherent in the enzyme, and has excellent performance. Ž<P>SOLUTION: The fuel cell is a biofuel cell having a structure comprising a positive electrode 2 and a negative electrode 1 arranged opposite to each other through an electrolyte layer 3 containing a buffering substance, an enzyme being immobilized on at least one of the positive electrode 2 and the negative electrode 2. An imidazole ring-containing compound is included as a buffering substance in the electrolyte layer 3. Further, at least one acid selected from a group consisting of acetic acid, phosphoric acid, and sulfuric acid is added. For the imidazole ring-containing compound, imidazole, 1-methylimidazole, 2-methylimidazole, 4-methylimidazole, or 2-ethylimidazole is used. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
