Description
Technical field
The utility model relates to technical field of microbial fuel battery, particularly relates to a kind of anode of microbiological fuel cell.
Background technology
At present; many countries are all faced with the Tough questions of environmental pollution and energy crisis in the world; along with the research and development of global new forms of energy and sustainable energy; the research of microbiological fuel cell (Microbial Fuel CellsMFC); the particularly research of anode of microbial fuel cell and negative electrode and manufacture, becomes the world today and solves one of important channel of this two hang-up of Environment and energy crisis.As the MFC technology processing pollutant and electrogenesis dual-use function, be subject to the extensive concern of various countries, electrogenesis effect of microbiological fuel cell and organic pollutant removal rate are the two large indexs in this field, and domestic and international research is mostly in scientific research or experimental stage, does not have substantial breakthrough.
MFC is the various materials utilized in different carbohydrate and waste water, carries out power conversion by microbial action, the electric transmission of respiration generation on cell membrane, then electronics transfers to galvanic anode from cell membrane, through external circuit, the electronics on anode arrives negative electrode, produces extrinsic current; The hydrogen ion produced is delivered to negative electrode by proton exchange membrane (PEM) simultaneously, reacts generation water at negative electrode proton and electronics, oxygen, realize the transmission of electric charge in battery, thus complete whole bio-electrochemical process and energy conversion process.Microbiological fuel cell is a kind of new technology combining waste water treatment and biological electrogenesis, can produce electric energy, and do not discharge pollutants while microbial degradation debirs.
MFC utilizes in the whole process of organic substance electrogenesis, and what play a decisive role is the transmission of electronics in anode region.In this process, the transfer of endocellular electricity utilizes the respiratory chain in microbiological oxidation metabolism, make electronics through nadh dehydrogenase, ubiquinone, ubiquinone, cytochromes etc., or the hydrogenase on microbial film surface migrates out cell, then extracellular electronics also must by with film hazardous substance, or dissolvable redox amboceptor is transferred on electrode.
The speed of transfer rate will affect the number of the final electricity generation ability of MFC, and in the middle of the factor of transfer rate, the selection of electrode material has conclusive impact to final capacity efficiency, and the absorption property of anode material and electric conductivity are leading indicators; Current anode material mainly with conventional carbon for base material, the homogenous material comprising carbon paper, carbon cloth, graphite flake, graphite rod, carbon felt and foamy graphite makes, and to the exploitation dynamics of the modification of existing anode material and anode material not enough.
