Microbial fuel cell (MFC) systems have been developed for potential use as power sources, along with several other applications, with bacteria as the prime factor enabling electrocatalytic activity. Limited voltage and current production from unit cells limit their practical applicability, so stacking multiple MFCs has been proposed as a way to increase power production. Special attention is paid to voltage reversal (VR), a common occurrence in stacked MFCs, and to identifying the mechanisms underlying this phenomenon. We also proposed realistic perspectives on stacked MFCs in an effort to control and suppress VR by balancing the kinetics in the system, such as using enriched electroactive microorganisms or altering the circuitry mode.

控制微生物燃料电池中的电压反转。

微生物燃料电池（MFC）系统已被开发为可潜在地用作动力源，以及其他几种应用，其中细菌是实现电催化活性的主要因素。从单元电池产生的有限的电压和电流限制了它们的实际适用性，因此已经提出了堆叠多个MFC作为增加功率产生的方法。特别要注意电压反转（VR），这是堆叠式MFC中的常见现象，并且要确定这种现象的潜在机理。我们还提出了关于堆叠式MFC的现实观点，以通过平衡系统动力学来控制和抑制VR，例如使用富集的电活性微生物或改变电路模式。
