Cathodic and anodic biofilms in single chamber microbial fuel cells

The aim of this work is to investigate the properties of biofilms, spontaneously grown on cathode electrodes of single-chamber microbial fuel cells, when used as catalysts for oxygen reduction reaction (ORR). To this purpose, a comparison between two sets of different carbon-based cathode electrodes is Cited by: 4 The oxygen reduction due to microaerophilic biofilms grown on graphite cathodes (biocathodes) in Single Chamber Microbial Fuel Cells (SCMFCs) is proved and analysed in this paper.

Cathodic and anodic biofilms in Single Chamber Microbial Fuel Cells.

The oxygen reduction due to microaerophilic biofilms grown on graphite cathodes biocathodes in Single Chamber Microbial Fuel Cells SCMFCs is proved and analysed in this paper. Pt-free cathode performances are compared with those of different platinum-loaded cathodes, before and after the biofilm growth.

Membraneless SCMFCs were operating in batch-mode, filled with wastewater. A substrate fuel of sodium acetate 0. A maximum of power densities, up to 0. The power output was almost constant with an acetate concentration of 0. Current densities varied in the range of Am -2 cathode area of 5 cm 2. Quasi-stationary polarization curves performed with a three-electrode configuration on cathodic and anodic electrodes showed that the anodic overpotential, cathodic and anodic biofilms in single chamber microbial fuel cells, more than the cathodic one, may limit the cathodic and anodic biofilms in single chamber microbial fuel cells density in the SCMFCs for a long-term operation.

Abstract The oxygen reduction due to microaerophilic biofilms grown on graphite cathodes biocathodes in Single Chamber Microbial Fuel Cells SCMFCs is proved and analysed in this paper. Publication types Research Support, Non-U. Substances Waste Water Platinum Graphite Calcium Carbonate Oxygen.

Biohybrid Cathode in Single Chamber Microbial Fuel Cell

 · Microbial fuel cells (MFCs) are a rapidly growing technology for energy production from wastewater and biomasses. In a MFC, a microbial biofilm oxidizes organic matter and transfers electrons from reduced compounds to an anode as the electron acceptor by extracellular electron transfer (EET). The aim of this work was to characterize the microbial Cited by: 58  · The oxygen reduction due to microaerophilic biofilms grown on graphite cathodes (biocathodes) in Single Chamber Microbial Fuel Cells (SCMFCs) is proved and analysed in this paper. Pt-free cathode performances are compared with those of different platinum-loaded cathodes, before and after the biofilm blogger.com by:  · In the following sections, the single chamber microbial fuel cells with the microalgal biofilm on the cathode were named m-SCMFCs, while the control was named c-SCMFC. All of the SCMFCs were monitored in two sequential batch experiments at room temperature (20–25 °C). Anodic and cathodic immobilizationCited by: 81
