Copper anode corrosion affects power generation in microbial fuel cells
Non-corrosive, carbon-based materials are usually used as anodes in microbial fuel cells (MFCs). In some cases, however, metals have been used that can corrode (e.g. copper) or that are corrosion resistant (e.g. stainless steel, SS). Corrosion could increase current through galvanic (abiotic) current production or by increasing exposed surface area, or decrease current due to generation of toxi...
متن کاملAnode 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 کاملEvaluation of multi-brush anode systems in microbial fuel cells.
The packing density of anodes in microbial fuel cells (MFCs) was examined here using four different graphite fiber brush anode configurations. The impact of anodes on performance was studied in terms of carbon fiber length (brush diameter), the number of brushes connected in parallel, and the wire current collector gage. MFCs with different numbers of brushes (one, three or six) set perpendicul...
متن کاملHigh rate copper and energy recovery in microbial fuel cells
Bioelectrochemical systems (BESs) are a novel, promising technology for the recovery of metals. The prerequisite for upscaling from laboratory to industrial size is that high current and high power densities can be produced. In this study we report the recovery of copper from a copper sulfate stream (2 g L(-1) Cu(2+)) using a laboratory scale BES at high rate. To achieve this, we used a novel c...
متن کاملComparison in performance of sediment microbial fuel cells according to depth of embedded anode.
Five rigid graphite plates were embedded in evenly divided sections of sediment, ranging from 2 cm (A1) to 10 cm (A5) below the top sediment layer. The maximum power and current of the MFCs increased in depth order; however, despite the increase in the internal resistance, the power and current density of the A5 MFC were 2.2 and 3.5 times higher, respectively, than those of the A1 MFC. In addit...
