Compared to many of the traditional green energy, such as wind power, solar power and geothermal power, bio-fuel cell (biological fuel cell) is a growing alternative energy technologies. Wherein the microbial fuel cell (microbial fuel cell, MFC) is a microorganism by ATP (adenosine triphosphate, ATP) the oxidation of organic or inorganic compounds to produce chemical energy, the electrons (electron) is transferred to a final electron acceptor current generating system [ 1].
Unlike limit oxidation of the electron acceptor and enzyme chemical fuel cell fuel cell, the microbial fuel cell has a more powerful adaptive [2]. So far, the different species, such as: genus Geobacter, Enterobacter, Shewanella and Bacillus joann fabric Tested production of microbial fuel cells can have the best power. Recent research joann fabric focuses on microbial fuel cell filling mixed microbial strains, particularly with regard to their suitability for nutrient joann fabric sources: bacteria each other's competitiveness and the overall trend, making the system more stable and better, and the study found Compared to the pure culture strain of system currents higher density can be obtained [3].
The main principle of the biofuel cell by the microorganism as a catalyst, the chemical energy into electrical energy. Which system components comprising an anode (anode), a cathode (cathode) and the semi-permeable joann fabric membrane joann fabric (semi-permeable membrane). As shown below, bio-fuel cell anode containing organics poured fuel for microbial reactions, which provides microorganisms matrix (fuel); ion semi-permeable membranes allow only positively joann fabric charged through, namely; cathode is poured oxygen as the oxidant protons (proton, H +) generated in the anode, the film between the groove between the anode and the cathode tank to separate. In order to avoid the occurrence of the anode reaction mechanism, therefore the system joann fabric is a closed system, so that the anode into the anaerobic state, the anodic reaction does not occur, and the cathodic reaction poured produce oxygen concentrations decrease proton induced anode through a semi-permeable membrane joann fabric to produce infiltration .
Since the current is proportional to the anode and cathode of the substrate concentration in the consumption of electron acceptors joann fabric and microbial fuel cells are produced, it can be to calculate the Coulomb joann fabric (coulomb) yield, compared to traditional analysis of biological oxygen demand methods, biological sensors quantitative or semi-quantitative approach can quickly obtain joann fabric the wastewater BOD [5,6], so the bio-fuel cell can also be used in bio-sensors to the measured biological joann fabric oxygen joann fabric demand, now associated Scholars have also committed to the development of biological sensors [7].
