Microbial fuel cells (MFCs) are devices that utilize microorganisms attached to an electrode as catalysts oxidize organic or inorganic matter, generating electricity. However, MFCs have traditionally suffered from limited charge generation by microorganisms, resulting in relatively low power output. Additionally, conventional could not store charge. In this study, a capacitive composite biological anode material, comprising polypyrrole/chitosan (PPy/CS), was developed on carbon felt (CF) substrate. This leveraged the energy storage capabilities of polypyrrole well excellent biocompatibility chitosan. Consequently, prepared exhibited significant advantages, including large specific capacity, substantial surface area, efficient electron transport, and biocompatibility. equipped with CF/PPy/CS anodes achieved maximum density 7594.9 mW/m3, which 2.8 times higher than control anode. Moreover, stored (Qs) for modified 121.6 C/m2, representing 1.53-fold increase compared high-throughput measurement method employed analyze microbial community after modification. The results study offered valuable insights theoretical guidance development utilizing materials, thereby promoting recovery actual wastewater.
