<p><P>PROBLEM TO BE SOLVED: To generate hydrogen gas friendlily to global environments and store it in free carrying, and to provide a biofuel cell excellent in conveyability capable of easily extracting hydrogen gas stored. <P>SOLUTION: The biofuel cell is to be provided with a hydrogen-generating part for generating hydrogen supplied to a hydrogen electrode, which is equipped with a metabolic gas storage means made of solid or half-solid culture medium for storing inside in an air bubble state metabolic gas generated from hydrogen-bearing bacteria cultivated by planting bacteria, filling saccharide and cultivating the same, a metabolic gas releasing means releasing the metabolic gas stored in the metabolic gas storage means in an air bubble state by lowering viscosity of the culture medium, and a hydrogen gas sorting means extracting hydrogen gas from the metabolic gas released from the metabolic gas storage means. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
