The efficiency of microbial fuel cells (MFCs) is affected by several factors such as activation overpotentials, ohmic losses and concentration polarization. These factors are handled in micro-sized MFCs using special electrodes with physically or chemically modified surfaces constructed with specified materials. Most of the existing μLscale MFCs show great potential in rapid screening of electrochemically-active microbes and electrode performance; although they generate significantly lower volumetric power density compared with their mL counterparts because of their high internal resistance. This review presents the development of microfluidic MFCs, with summarization of their advantages and challenges, and focuses on the efforts done to minimize the adverse effects of internal resistance (ohmic and non-ohmic) on their performance.
微生物燃料电池 (MFC) 的效率受到多种因素的影响，例如活化过电位、欧姆损耗和浓度极化。在微尺寸 MFC 中，使用具有物理或化学改性表面的特殊电极来处理这些因素，这些电极由指定材料构建。大多数现有的 μL 级 MFC 在快速筛选电化学活性微生物和电极性能方面显示出巨大的潜力；尽管由于其高内阻，与 mL 级 MFC 相比，它们产生的体积功率密度明显较低。本综述介绍了微流控 MFC 的发展，总结了它们的优点和挑战，并重点介绍了为最小化内阻（欧姆和非欧姆）对其性能的不利影响而做出的努力。
