Dynamic power response of microbial fuel cells under external electrical exciting

More related studies of microbial fuel cells (MFCs) have been noted recently because of the feature that MFCs could use bacteria to convert organic matter from wastewater into electricity. But facing the slow dynamic response and low power density of MFCs, a technique using external physical excitin...

In addition, a maximum electric charge of 358.9 × 10−3C in a system whose Oxidation-Reduction Potential (ORP) was −219 mV was obtained in the case of MFCE-4.8 and was 4.07 times that of the MFCoriginal. These findings will be useful to the application of micro-MFCs, especially for those electrically impacting wastewater environments.
