Microbial fuel cells (MFCs) can be used for electricity generation via bioconversion of wastewater and organic waste substrates. MFCs also hold potential for production of certain chemicals, such as H2 and H2O2. The studies of electricity generation in MFCs have mainly focused on the microbial community formation, substrate effect on the anode reaction, and the cathode's catalytic properties. To improve the performance of MFCs, the initiation process requires more investigation because of its significant effect on the anodic biofilm formation. This review explores the factors which affect the initiation process, including inoculum, substrate, and reactor configuration. The key messages are that optimal performance of MFCs for electricity production requires (1) understanding of the electrogenic bacterial biofilm formation, (2) proper substrates at the initiation stage, (3) focus on operational conditions affecting initial biofilm formation, and (4) attention to the reactor configuration.
微生物燃料电池（MFC）可以通过废水和有机废物基质的生物转化来发电。MFC 也有潜力生产某些化学品，如 H2 和 H2O2。MFC 发电的研究主要集中在微生物群落的形成、底物对阳极反应的影响以及阴极的催化特性上。为了提高 MFC 的性能，由于其对阳极生物膜形成有显著影响，因此需要对启动过程进行更多的研究。本综述探讨了影响启动过程的因素，包括接种物、底物和反应器构型。关键信息是，要实现 MFC 发电的最佳性能，需要（1）了解产电细菌生物膜的形成，（2）在启动阶段使用合适的底物，（3）关注影响初始生物膜形成的操作条件，以及（4）注意反应器构型。
