Influence of nitrogen limitation on performance of a microbial fuel cell
We describe the operation of a microbial fuel cell (MFC) system operating on a synthetic wastewater (acetic acid), under conditions of increasing nitrogen limitation. Two MFCs were operated under feed conditions which spanned a range of TKN/COD values of 1.6–28 mg/g. Stable operation was observed in all cases, even when no ammoniacal nitrogen was added to the cell. Improved electrochemical ...

Effect of various micro-porous layer preparation methods on the performance of a proton exchange membrane fuel cell
Proton exchange membrane fuel cells (PEMFCs) have been widely studied and discussed in the field of energy owing to their high energy efficiency and low waste emissions. A PEMFC uses hydrogen gas as a fuel, and works by causing hydrogen ions to link up with oxygen, producing liquid water as its sole by-product. The design of a PEMFC's micro-porous layer (MPL) can not only enhance cell ...

Controlling methanogenesis and improving power production of microbial fuel cell by lauric acid dosing
Methanogens compete with anodophiles for substrate and thus reduce the power generation and coulombic efficiency (CE) of the microbial fuel cell (MFC). Performance of a baked clayware membrane MFC inoculated with mixed anaerobic sludge pretreated with lauric acid was investigated in order to enhance power recovery by controlling methanogenesis. In the presence of lauric acid pretreated ...

The effects of electrode spacing on the performance of microbial fuel cells under different substrate concentrations
In this study, the electricity generation and organic removal in microbial fuel cells (MFCs) were examined for electrode spacing (ES) covering 5.8, 10.2, 15.1, and 19.5 cm, and for each ES the MFCs were discharged with a series of influent substrates (CODin). Results indicate that organic removal was related to CODin but not to ES. Best chemical oxygen demand (COD) removals of ...

Performance of denitrifying microbial fuel cell subjected to variation in pH, COD concentration and external resistance
The effects of pH, chemical oxygen demand (COD) concentration and external resistance on denitrifying microbial fuel cell were evaluated in terms of electricity generation characteristics and pollutant removal performance. The results showed that anodic influent with weakly alkaline or neutral pH and cathodic influent with weakly acidic pH favored pollutant removal and electricity generation. ...

Electricity generation in low cost microbial fuel cell made up of earthenware of different thickness
Performance of four microbial fuel cells (MFC-1, MFC-2, MFC-3 and MFC-4) made up of earthen pots with wall thicknesses of 3, 5, 7 and 8.5 mm, respectively, was evaluated. The MFCs were operated in fed batch mode with synthetic wastewater having sucrose as the carbon source. The power generation decreased with increase in the thickness of the earthen pot which was used to make the anode chamber. ...

Membrane Electrode Assembly (MEA) Activation Procedures
Why is an activation procedure or break-in necessary for a membrane electrode assembly (MEA)? A large reason for performing an activation procedure or break-in is to properly humidify the membrane portion of the MEA that was dried out during the hot press stage of the membrane electrode assembly(MEA) production. MEAs will not work well when they are not fully humidified (see article: Why is ...
