Experimental Investigation of Electricity Generation in Dual Chamber Microbial Fuel Cell- Effective Parameters in Cathode Chamber
, M.Sc. Thesis Sharif University of Technology ; Kariminia, Hamid Reza (Supervisor) ; Roshandel, Ramin (Supervisor)
Abstract
Two major challenges facing countries all around the world are the demand for renewable energy resources and treatment of large quantities of industrial and household wastewaters. One of the new and environmentally acceptable methods to produce green energy is Microbial Fuel Cells (MFCs), which has been noted by many researchers in recent years. MFC is a new technology which has the ability to produce green energy along with treatment of wastewater stream, based on oxidation of organic maters through microbial metabolism. In this study we investigated the effects of different cathode chamber parameters on operation and efficiency of a two chamber MFC at laboratory scale. These parameters...
Performance Evaluation of Nitrate Removal from Drinking Water Using Microbial Fuel Cell

Abstract
Nitrate can be used as an oxidant in a cathode chamber of microbial fuel cell. Nitrate is known to be a pollutant of water particularly underground water and is considered a carcinogen of water. Nitrate was used in the cathode chamber of a microbial fuel cell as an oxidant that lead to simultaneous generation of electricity, removal of organic matter in anode, and removal of nitrate in the cathode. Using nitrate generated a voltage of 151 mV with an external resistance of 1000Ω. The maximum power density achieved was 1.375 mW/m2 with an external resistance of 800Ω. Seven days after the cell became operational and without the presence of a catalyst, the amount of COD had decreased by 25...

Abstract
Enzymatic decolorization of reactive blue 221 (RB221) using laccase was investigated in a dual-chamber microbial fuel cell (MFC). Suspended laccase was used in the cathode chamber in the absence of any mediators in order to decolorize RB221 and also improve oxygen reduction reaction in the cathode. Molasses was utilized as low cost and high strength energy source in the anode chamber. The capability of MFC for simultaneous molasses and dye removal was investigated. A decolorization efficiency of 87% was achieved in the cathode chamber and 84% COD removal for molasses was observed in the anode chamber. Laccase could catalyze the removal of RB221 and had positive effect on MFC performance as...
