Thing fuel cell.
Background technology
Microbiological fuel cell (Microbial Fuel Cells, MFCs) is a kind of utilization microorganism by Organic substance
Chemical energy is directly translated into the device of electric energy, with fuel source is extensive, reaction condition gentle, good biocompatibility, is producing
Wastewater treatment unique advantage is carried out while electric energy, becomes the focus of global regenerative resource researcher concern.Affect MFC performances
Factor have a lot, including microbe species, substrate, cathod catalyst, cathode electronics receptor, procedure parameter optimization, electrode material
Material, structure of reactor etc..Researcher is just carrying out substantial amounts of experimentation to factors above.Wherein, with air in oxygen make
For cathode electronics receptor air cathode microbial fuel cell be great scale application potential quality at present one kind.Learn both at home and abroad
Person is widely probed into for the optimization of air cathode catalyst and the direction such as preferred of material all expand deeply.By a large amount of
Experimentation, the performance of air cathode and cost control have larger lifting.
However, major part air cathode research at present adopts self-respiration type air cathode structure, cathode construction to be two dimension
Planar structure.Meanwhile, partial air negative electrode employs the metallic catalyst of costliness, and this is for following practical application unrealistic.
Therefore, researcher constructs bubble type air cathode, and negative electrode is stacking bed using activated carbon granule.Which greatly enhances negative electrode electricity
The specific surface area of pole, so as to lifting the battery performance of MFC.However, this particle packing bed flow resistance is larger, and it is unfavorable for
The motion upwards of air bubble, can cause the accumulation of air bubble, reduce the effective area of reaction on the contrary.Additionally, activated carbon
The electric conductivity of grain is simultaneously bad, and the internal resistance of battery can be caused larger.
Therefore, it is quite necessary to a kind of bubbling air of the features such as finding low cost, good conductivity, little bubbly flow resistance
Cathode construction, to meet MFC future practical application requests.
Content of the invention
The technical problem to be solved is to provide a kind of microorganism of bamboo charcoal bundled tube bubbling air cathode construction
Fuel cell.
In order to solve above-mentioned technical problem, technology according to the present invention scheme, a kind of bamboo charcoal bundled tube bubbling air negative electrode
The microbiological fuel cell of structure, including anode electrode and cathode electrode, it is characterised in that：Anode electrode is by several vertical rows
The carbon brush of row is constituted, and cathode electrode is made up of several bamboo charcoal tubes arranged vertically；Anode electrode is arranged on the bottom of battery, cloudy

External air pump connects；The bottom of battery is provided with anolyte import and export, at the top of battery, is provided with bubble exit.
The present invention using carbonization after bamboo charcoal tube there is the characteristic of porous, greatly increased contact of the electrode with electrolyte
Area, promotes the reaction of negative electrode；Bamboo trunk wide material sources, cheap.Carbonization technique is ripe, simple；The vertical cloth of bamboo charcoal tube bank
It is equipped with the motion upwards in the bamboo charcoal tube and outside bamboo charcoal tube beneficial to bubble, it is to avoid the aggregation of air bubble；And through pyrocarbon
Bamboo charcoal tube electric conductivity after change preferably, reduces the internal resistance of battery；Bubbling increased disturbance, enhance between electrolyte and electrode
Mass transfer.The employing of air cathode, does not result in pollution in actual applications, and air is conveniently easy to get, and is that one kind is managed very much
The electron acceptor that thinks.
A kind of beneficial effect of the microbiological fuel cell of bamboo charcoal bundled tube bubbling air cathode construction of the present invention
It is：The present invention using bamboo charcoal tube as cell cathode, carbon brush blasts air as galvanic anode using air pump, not merely with
The excellent conductive capability of bamboo charcoal and porosity characteristic, air pump blast the efficiency of transmission that air has also speeded up material in reactor,
Improve the performance of battery；The present invention has low cost, good conductivity, bubbly flow resistance little, the features such as pollution-free, can be extensive
Apply in fields such as the energy, chemical industry, environmental protection.
