Microbial fuel cell using electron absorber having high reduction potential, and method of generating electric energy using same

A microbial fuel cell comprising an anode chamber, a cathode chamber, a separation membrane positioned between the anode chamber and the cathode chamber, and an electrolysis cell,

• wherein the anode chamber comprises an anode on which a microbial film is formed on the surface and an organic solution that is an electron donor as a negolyte, and the organic solution is continuously supplied to the anode chamber,
• the cathode chamber comprises a cathode which is a conductor electrode on which a microbial film is not formed on the surface, and an electron absorber solution as a posolyte,
• the electrolysis cell comprises a cathode and an anode to which power is applied, and the reduced posolyte transferred from the cathode chamber,
• the reduced posolyte transferred from the cathode chamber is regenerated through electrolysis using external power, and the regenerated posolyte is supplied back to the cathode chamber,
• hydrogen gas generated in the cathode chamber due to the electrolysis performed in the electrolysis cell is discharged to the outside of the electrolysis cell and
• the separation membrane is provided with one or more O-rings that can prevent leakage.
