NOVELTY - A microbiological fuel cell system comprises a bioreactor having a cathode chamber and an anode chamber, respectively comprising cathode and anode electrodes. The cathode and anode chambers comprise microbiological active matter. The cathode chamber comprises an aeration device used for blowing air into the cathode chamber. It is used for processing the water flow, and the reactor has a baffle board having a channel for connecting the two pole chambers. The two pole chambers are separated by the baffle board.    USE - A microbiological fuel cell system for processing microbiological sewage and generating electric energy (claimed).    ADVANTAGE - The structure is simple, the cost is low, and the system does not have proton exchange membrane.    DETAILED DESCRIPTION - A microbiological fuel cell system comprises a bioreactor having a cathode chamber and an anode chamber, respectively comprising cathode and anode electrodes. The cathode and anode chambers comprise microbiological active matter. The cathode chamber comprises an aeration device used for blowing air into the cathode chamber. It is used for processing the water flow, and the reactor has a baffle board having a channel for connecting the two pole chambers. The two pole chambers are separated by the baffle board. The water flow is processed by the microbiological active matter in the anode chamber. It flows into the cathode chamber to process. The protons generated in the anode chamber are transferred by taking the water flow in the channel as the carrier. The bioreactor generates electric energy while it processes the water flow. An INDEPENDENT CLAIM is included for method for processing microbiological sewage and generating electric energy, comprising processing the water flow flowing over the anode chamber by microbiological active matter; generating the proton and electron; transferring the protons in the anode chamber by taking the water flow in the channel as the carrier; and connecting two pole chambers electrically in the reactor, and generating the electric energy. The water power stopping time is 2-99 (preferably 48-77) hours, and the density value of chemical oxygen demand before processing the sewage is 100-10000 (preferably 1000-3000) mg/L.    DESCRIPTION OF DRAWING(S) - The drawing is a schematic view of the microbiological fuel cell system.
