Abstract
The anode section, as an electron-producing site, determines the power performance and pollutant removal in Microbial Fuel Cells (MFCs). However, the Extracellular Electron Transfer (EET) process limits the production of bioelectricity. In this study, the role of Conjugated Oligoelectrolytes (COEs) in catalyzing bacterial activity for bioelectric current generation was investigated. In this regard, a COE named Tetra[4-1-(3-Methylimidazolium Chloride)[Butyl[Ferrocene (TMBF+)] was synthesized, and the increase in anodic current output through the MFC device was examined. Electrochemical analyses demonstrated excellent performance in bioelectric current generation for cells modified with TMBF+. The tolerance threshold of the cells modified with COEs for various COE concentrations was evaluated using Chronoamperometry (CA). Additionally, the power performance of the MFC showed a maximum value of 138.97 mW/m² for cells modified with TMBF+, compared to unmodified cells (72.2 mW/m²). The results indicated that modifying cell membranes with COEs is an appropriate method to facilitate the EET process and produce bioelectricity.
