Electricity production of a microbial fuel cell stack integrated into a sink drain pipe

Electricity production of a microbial fuel cell stack integrated into a sink drain pipe In this study, five two-chambered microbial fuel cells (MFCs) were hydraulically connected in series to constitute a MFC stack, which was integrated into a sink drain pipe for kitchen wastewater treatment. Performances of the MFC stack operating with artificial and real wastewater were studied. Considering the practical application, the voltage response to different flow rates and temperatures of the substrate was also investigated. It was found that the MFC stack could achieve a reasonable performance, with an average open circuit voltage of 3.44 ± 0.02 V, a peak power of 45.74 ± 1.39 mW (i.e. 809.27 mW/m2) and a coulombic efficiency of 78.2 ± 3.6 %. The MFC performance was disturbed by the flushing process, but could recover after a few minutes. The results also suggest that the MFC stack can operate after flushing by the substrate at 50 °C, above which irreversible performance deterioration was observed. The proposed MFC stack is expected to serve as a potential power source for lighting and low-power devices, especially in off-grid rural areas. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals

Abstract

In this study, five two-chambered microbial fuel cells (MFCs) were hydraulically connected in series to constitute a MFC stack, which was integrated into a sink drain pipe for kitchen wastewater treatment. Performances of the MFC stack operating with artificial and real wastewater were studied. Considering the practical application, the voltage response to different flow rates and temperatures of the substrate was also investigated. It was found that the MFC stack could achieve a reasonable performance, with an average open circuit voltage of 3.44 ± 0.02 V, a peak power of 45.74 ± 1.39 mW (i.e. 809.27 mW/m2) and a coulombic efficiency of 78.2 ± 3.6 %. The MFC performance was disturbed by the flushing process, but could recover after a few minutes. The results also suggest that the MFC stack can operate after flushing by the substrate at 50 °C, above which irreversible performance deterioration was observed. The proposed MFC stack is expected to serve as a potential power source for lighting and low-power devices, especially in off-grid rural areas.
