Embodiment Construction

[0034] The principles and features of the present invention are described below in conjunction with examples, which are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0035] The reaction stages of the battery pack are taken as an example of three stages, and the MFC reaction modules can be flexibly increased or decreased according to the engineering needs in the application.

[0036] Such as figure 1 , figure 2 As shown, the structural size of the cuboid integrated multi-stage microbial fuel cell group is 60cm×20cm×50cm (length*width*height), and the occupied capacity of the single-stage MFC is 20cm×20cm×50cm (length*width*height). A three-stage MFC is set up, that is, three single cells; the single-stage MFC is separated by a diagonal plate, and the two chambers are respectively used as a single-stage anode chamber and a cathode chamber, and the double chambers are equal in volume, each occupying a capacity of ...

Abstract

The invention relates to an integral multistage microorganism fuel battery pack. The integral multistage microorganism fuel battery pack is formed by serially connecting a plurality of same cubical battery monomers; each battery monomer comprises an anode chamber and a cathode chamber; the anode chamber and the cathode chamber are separated along the diagonal lines of the battery monomers; a proton exchange diaphragm is arranged between the anode chamber and the cathode chamber; a medium inside the anode chamber and the cathode chamber of every two adjacent battery monomers is conveyed continuously, and the proton exchange diaphragm is arranged between the anode chamber and the cathode chamber. According to the integral multistage microorganism fuel battery pack, a conventional microorganism fuel battery structure design is broken, the anode chamber and the cathode chamber of a multistage MFC are nested and fused mutually, the distance between the anode chamber and the cathode chamberis reduced obviously, and the internal resistance of the system is reduced to the maximum extent. Bidirectional interconnecting transfer of protons is formed between adjacent single-stage MFCs, the transmission path cross sections of protons between the anode chamber and the cathode chamber are greatly expanded, and the proton transfer efficiency can be promoted obviously.

Description

technical field [0001] The invention belongs to the technical field of waste water resource utilization and new energy development, and relates to an integrated multi-stage microbial fuel cell group. Background technique [0002] In recent years, Microbial Fuel Cell (MFC) has received extensive attention from researchers at home and abroad, and laboratory-scale research results have emerged in an endless stream. Wastewater is rich in organic matters, which are used as target pollutants in water treatment projects for purposeful removal. However, a large amount of organic matter contained in wastewater can be used as a biomass raw material for MFC to supply electrogenic microorganisms. Electrogenic microorganisms convert chemical energy into electrical energy through metabolism, and can output it through an external circuit, thereby realizing the combination of wastewater treatment and electrical energy production. Double benefit. [0003] The microbial fuel cell is calcula...
