Claim Text:
1. A method for producing a biological fuel cell, the method comprising: (a) immobilizing an enzyme crystal onto an electroconductive base material, thereby forming an electrode comprising an enzyme crystal immobilized thereon; (b) forming the enzyme-immobilized electrode of (a) so that an anode and a cathode face each other; and (c) arranging an ion-conductive material so as to isolate the anode and cathode from each other, thereby producing the biological fuel cell, wherein the electroconductive base material is optionally connected to an external electrical circuit; wherein the enzyme crystal serves as an electrode catalyst; wherein the enzyme has an amino acid sequence of SEQ ID NO: 2, 4, 6, and 8; and wherein the enzyme is selected from the group consisting of pyrroloquinoline quinone-dependent glucose dehydrogenase from
