Electrochemical 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...
متن کاملA 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 کاملAir humidity and water pressure effects on the performance of air-cathode microbial fuel cell cathodes
To better understand how air cathode performance is affected by air humidification, microbial fuel cells were operated under different humidity conditions or water pressure conditions. Maximum power density decreased from 1130 30 mW m 2 with dry air to 980 80 mW m 2 with water-saturated air. When the cathode was exposed to higher water pressures by placing the cathode in a horizontal position, ...
متن کاملThe use of nylon and glass fiber filter separators with different pore sizes in air-cathode single-chamber microbial fuel cells
Separators are needed in microbial fuel cells (MFCs) to reduce electrode spacing and preventing electrode short circuiting. The use of nylon and glass fiber filter separators in single-chamber, aircathode MFCs was examined for their effect on performance. Larger pore nylon mesh were used that had regular mesh weaves with pores ranging from 10 to 160 mm, while smaller pore-size nylon filters (0....
متن کاملSpray-on polyvinyl alcohol separators and impact on power production in air-cathode microbial fuel cells with different solution conductivities.
Separators are used to protect cathodes from biofouling and to avoid electrode short-circuiting, but they can adversely affect microbial fuel cell (MFC) performance. A spray method was used to apply a polyvinyl alcohol (PVA) separator to the cathode. Power densities were unaffected by the PVA separator (339±29mW/m(2)), compared to a control lacking a separator in a low conductivity solution (1m...
