The concept of the microbial fuel cell (MFC) has existed for over 100 years, but only within the last decade, the practical implementation has become conceivable due to microbial and technical progress. This review article presents available strategies to increase the limiting extracellular electron transfer (EET) in the anode space of MFCs. Therefore, organism‐based improvements as well as the effects of (bio–)polymers and redox mediators on ETT will be demonstrated.

有针对性地改善微生物燃料电池中阳极电子转移的策略

微生物燃料电池（MFC）的概念已经存在了100多年，但是仅在最近十年内，由于微生物和技术的进步，实际的实现才成为可能。这篇综述文章提出了可利用的策略，以增加MFCs阳极空间中的极限细胞外电子转移（EET）。因此，将证明基于生物的改进以及（生物）聚合物和氧化还原介体对ETT的影响。
