Positive Effect

Sediment microbial fuel cells (SMFCs) produce electricity through the bacterial oxidation of organic matter contained in the sediment, but the power density is limited and needs to be improved. In this study, a new design of a fined-type cathode with carbon cloth embedded partly, as opposed to completely, in SMFCs were utilized. As a result, the design allowing the cathode to contact air will have a positive effect on the power performance and decrease the resistance of the inner system. The power density in the cases where the cathode was about half soaked was about two folds the case where it was soaked completely. Furthermore, SMFCs would also be seen as a driving force in hastening the COD removal because it was about 1.92-folds the COD removal of the cases where SMFCs where not present. These findings can be applied to sewage treatment and improving the power performance in SMFCs.

Key Factors

Poor energy output and high cost are the key factors to inhibit the development and application of microbial fuel cells (MFCs). Different types of modification techniques for anode material are suggested to improve power performance in MFCs. nanoFe2O3 is characteristics of no toxicity, biocompatibility and low cost. In this work, stainless steel mesh (SSM), ultracapacitor activated carbon with SSM (AcM), Fe2O3 added AcM (AMF) anodes are investigated to improve MFCs performance. The highest maximum power density (806 ± 26 mW·m-2) is obtained in AMF anode, which is 11 % higher than that of AcM (730 ± 27 mW·m-2), and 57 folds higher than that of SSM anode (12 ± 0.7 mW·m-2). The semi-conducting properties of passive film on the anode surface play a rather important role in anodic reaction by Mott-Schottky analysis. Tafel test demonstrates that the exchange current density (8.36×10-4 A·m-2) is improved by 20 % for AMF compared with AcM control (6.93×10-4 A·m-2). These results show AcM is suitable as MFCs anode, and further addition of Fe2O3 can increase the extracellular electron transfer in that way increase power production in MFCs.
