Anode materials for sediment microbial fuel cells.
INTRODUCTION Plant microbial fuel cells (P-MFCs), and more general sediment microbial fuel cells, make use of electricigenic metabolism of microorganisms in anoxic soils and sediments. Electricigenic microorganisms are able to respire organic carbon from the soil or sediment with an electrode as final electron acceptor [1]. In this work, the focus is on the anode buried in the sediment, the ele...
متن کاملBoosting Power Density of Microbial Fuel Cells with 3D Nitrogen‐Doped Graphene Aerogel Electrode
A 3D nitrogen-doped graphene aerogel (N-GA) as an anode material for microbial fuel cells (MFCs) is reported. Electron microscopy images reveal that the N-GA possesses hierarchical porous structure that allows efficient diffusion of both bacterial cells and electron mediators in the interior space of 3D electrode, and thus, the colonization of bacterial communities. Electrochemical impedance sp...
متن کاملComparison of Conduction Based and Mediator Based Models for Microbial Fuel Cells
Microbial fuel cells (MFCs) are processes used for simultanuous bioenergy capturing and waste treatment. In this study, a model for MFCs based upon a conduction mechanism for electron transfer is proposed, which integrates substrate utilization, current production and conduction and microbial distribution and growth in batch flow mode. The outputs of the model and that of a mediator based mode...

متن کاملMetal-Free Carbon-Based Materials: Promising Electrocatalysts for Oxygen Reduction Reaction in Microbial Fuel Cells
Microbial fuel cells (MFCs) are a promising green approach for wastewater treatment with the simultaneous advantage of energy production. Among the various limiting factors, the cathodic limitation, with respect to performance and cost, is one of the main obstacles to the practical applications of MFCs. Despite the high performance of platinum and other metal-based cathodes, their practical use...
