A Single-Chamber Microbial Fuel Cell without an Air Cathode
Microbial fuel cells (MFCs) represent a novel technology for wastewater treatment with electricity production. Electricity generation with simultaneous nitrate reduction in a single-chamber MFC without air cathode was studied, using glucose (1 mM) as the carbon source and nitrate (1 mM) as the final electron acceptor employed by Bacillus subtilis under anaerobic conditions. Increasing current a...
متن کاملMicrobial community structures differentiated in a single-chamber air-cathode microbial fuel cell fueled with rice straw hydrolysate
BACKGROUND The microbial fuel cell represents a novel technology to simultaneously generate electric power and treat wastewater. Both pure organic matter and real wastewater can be used as fuel to generate electric power and the substrate type can influence the microbial community structure. In the present study, rice straw, an important feedstock source in the world, was used as fuel after pre...
متن کاملMicrobial fuel cell performance with a pressurized cathode chamber.
Microbial fuel cell (MFC) power densities are often constrained by the oxygen reduction reaction rate on the cathode electrode. One important factor for this is the normally low solubility of oxygen in the aqueous cathode solution, which creates mass transport limitation and hinders oxygen reduction at the electrocatalyst (platinum, Pt). Here, we increased the air pressure in the cathode chambe...
متن کاملIncreasing power generation for scaling up single-chamber air cathode microbial fuel cells.
Scaling up microbial fuel cells (MFCs) requires a better understanding the importance of the different factors such as electrode surface area and reactor geometry relative to solution conditions such as conductivity and substrate concentration. It is shown here that the substrate concentration has significant effect on anode but not cathode performance, while the solution conductivity has a sig...
متن کاملElectrochemical analysis of separators used in single-chamber, air-cathode microbial fuel cells
Polarization, solution-separator, charge transfer, and diffusion resistances of clean and used separator electrode assemblies were examined in microbial fuel cells using current–voltage curves and electrochemical impedance spectroscopy (EIS). Current–voltage curves showed the total resistance was reduced at low cathode potentials. EIS results revealed that at a set cathode potential of 0.3 V di...
