| Outline of Final Research Achievements |
Microbial fuel cell (MFC) technology has emerged as a promising solution in addressing these global challenges. MFCs, a technology with promising applications in power generation and wastewater treatment, still face challenges that limit their practical use. The issues of high internal resistivity and low power generation are key concerns for researchers. In this study, we evaluated the impact of Fe0 nanoparticles on MFC performance, specifically in power generation and organic matter degradation. We used two different samples of sludge and found that the maximum daily voltage in the control MFC filled with S2 (COD= 37802 mg/L) increased by 182 % compared to the MFC filled with S1 (COD= 5561 mg/L). However, the addition of Fe nanoparticles led to a reduction in the daily voltage by 31 % and 9 % for the MFCs filled with S1 and S2, respectively. These findings have significant implications, highlighting the importance of considering organic matter content in optimizing MFC response.
