spelling Microbially charged redox flow battery: coupling a bioelectrochemical cell with a redox flow batteryISMET 6 - General Meeting of the International Society for Microbial Electrochemistry and TechnologyRedox flow batteries (RFB) are electrochemical systems applied in the conversion and storage of chemical energy in electricity. Red ox chemical species (in soluble form) are the main responsible for the energy storage. Quinones are electroactive molecules applied in RFB because of their chemical and physical properties. The aim of this work is to develop an innovative technology to generate and storage the energy resultant from Bioelectrochemical system (BES). The strategy outlined was coupling a BES with a RFB that present potential to combine bioenergy production and storage in a microbially charged redox flow battery. Firstly, a BES system was studied with Geobacter su/furreducens as biocatalyst to convert a quinone (2,6-anthraquinone) in its respective reduced form, acetate being the carbon source used. The BES presented current intensities around 500 mA.m·2 and power densities around 2 wm· 2. The reduction was assessed visually by a typical colour change (from yellow to dark red) and by cyclic voltammetry. Simultaneously, as a control, the 2,6-anthraquinone was electrochemically reduced applying and controlling the cathode potential where the reduction was also observed by colour change and by cyclic voltammetry. In an RFB, the quinone bioreduced in tlie BES and electrochemically reduced in the electrochemical cell were studied using potassium hexacyanoferrate as the second redox chemical species for discharging/charging cycles in the RFB as the proof of concept of the microbially charged redox flow battery. The study was performed in a 25 cm2 single red ox flow cell (RF) with a constant current density of 0.2 mA.cm2 where coulombic efficiency, voltage efficiency and energy efficiency were observed for 10 cycles.info:eu-repo/semantics/publishedVersionUniversidade do MinhoSantos, M.
