<p><P>PROBLEM TO BE SOLVED: To provide a method of efficiently obtaining electric energy from an aqueous organic substance with a simple device. <P>SOLUTION: In the power generating method, one of the pair of electrodes as an anode is brought into contact with solution or slurry containing viable anaerobic microbes and an organic substance, and the other as a cathode is formed at least partly by a conductive porous material having pores in a structure, mesh or fibrous material. Then, the cathode is brought into contact with air with a contact interface of the air and water existent in the pores of the cathode, the cathode is separated from the solution or the slurry through an electrolyte film, and the cathode and the anode are electrically connected to form a closed circuit, whereby, a reduction reaction is made to proceed in the cathode with oxygen as an electron acceptor, and an oxidation reaction by the microbes is made to proceed in the anode with the organic substance as an electron donor. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
