Embodiment Construction

[0020] The following examples describe the present invention in more detail:

[0021] The present invention builds a square reactor, that is, a single-chamber microbial fuel cell without a diaphragm and without a mediator. figure 1 , The battery composition of the present invention includes a cathode 6 and an anode 7, and the two poles are placed on one side and inside of the reactor 2, respectively. The anode material is carbon felt, the cathode is a gas electrode containing metal catalysts such as Ag, and the distance between the two poles is 0.5-2.0cm. There is a water inlet 1 at the lower end of the reactor, and a water outlet 3 at the upper end. The upper part of the container has a sealing cover, and the sealing cover is provided with a reference electrode jack 8. The two electrodes are connected by copper wires and connected with the load 4 to form a closed loop. The adjustment range of the load is 1-10000Ω, and the electricity production performance data of the batter...

Abstract

The invention provides a method for improving the electron transfer capacity and output power of a microbial fuel cell, which is characterized in that antibiotics containing beta-lactam rings are added into fuel of the microbial fuel cell in a proportion of between 10 and 50mg/L. The antibiotics containing the beta-lactam rings are added into the fuel of the cell, and can break the integrity of cell membranes of microbes under the condition of small dose without influencing the activity of cells. Therefore, electrons can be transferred to the surface of an anode from the inside of the cells, the transfer resistance of the electrons is reduced greatly, the electron transfer capacity is improved, the generation efficiency of current is improved, the power output is improved, and the utilization capacity of the microbes on substrates is not reduced; and the greatest output power of the microbial fuel cell is improved greatly, and simultaneously penicillin added in the fuel can also be degraded by the microbial fuel cell without causing secondary environmental pollution.

Description

technical field [0001] The invention relates to a method for improving the performance of the microbial fuel cell, specifically a method for improving the electron transfer capability and output power of the microbial fuel cell. Background technique [0002] With the development of society, the problem of energy shortage has become increasingly prominent, and the extensive use of fossil fuels has caused serious environmental problems. The development of new clean energy and the adjustment of energy structure have become the consensus of the world. Microbial fuel cell (MFC) is a new type of device that uses microorganisms to directly convert chemical energy in biomass into electrical energy. Compared with conventional fuel cells, MFC uses microorganisms instead of expensive chemical catalysts, so it has more advantages: (1) a wide range of fuel sources, especially organic waste water and other wastes can be used; (2) the reaction conditions are mild, and it can be Operable; ...
