This approach can be used to revive reversed MFCs, as a supporting assistance current is applied through an assistance anode when voltage reversal occurs. However, when the assistance current is applied without control over the assistance current, voltage reversal is regenerated. Therefore, to control the assistance current, the suggested approach is complemented by the application of variable resistors between the anode and assistance electrode. As a result, the regenerated voltage reversal is restored and all voltages of MFC units in the stacked MFC remain positive. Thus, it is expected that this approach could resolve voltage reversal that occurs in series-connected MFCs, and thus increase the applicability of MFC technology to the production of practically usable electricity, with potential for extension to large-scale MFCs.
