Microbial fuel cell, power generator and sewage treatment system

摘要

A microbial fuel cell that suppresses deterioration of an ion exchange membrane is provided. A microbial fuel cell (1) is disposed between an anode electrode (30) to which a first microorganism (32) in contaminated water (2a) adheres, a cathode electrode (40) in contact with the atmosphere (2b), and between the anode electrode (30) and the cathode electrode (40). An anion exchange membrane 20. Further, the cathode electrode 40 and the anode electrode 30 are electrically connected outside. Moreover, the second microorganisms 42 functioning as a catalyst for promoting the oxygen reduction reaction in the cathode electrode 40 and existing in the atmosphere 2b adhere to the cathode electrode 40.
