Abstract Microbial fuel cell (MFC), a clean and promising technology that has the potential to tackle both environmental degradation global energy crisis, receives tremendous attention from researchers over recent years. The performance of each system component, including membrane electrode utilized in MFCs, great effect on efficiency converting chemical found organic waste power generation through bacterial metabolism. MFCs have diverse applications are growing day by developed countries. This review discusses recently available various wastewater treatment, biohydrogen production, hazardous removal, bioelectricity, robotics, biosensors, etc. There still several challenges (e.g., complexity, economic, commercialization, other operational factors) for large‐scale practical applications, particularly relatively low output delayed start‐up time, which is also reported this article. Moreover, factors materials, proton exchange system, substrate, electron transfer mechanism, pH, temperature, external resistance, shear stress feed rate) affect discussed detail. To resolve these issues, optimizations parameters presented. In previously published studies, paper indicates demonstrated densities ranging 2.44 3.31 W m − 2 , with Coulombic efficiencies reaching up 55.6% under optimized conditions. It achieved removal oxygen demand (COD), total carbon (TOC), antibiotics 93.7%, 70%, 98%, respectively. Finally, highlights future perspective full‐scale applications.

Microbial fuel cells (MFCs) present a promising green technology for wastewater treatment while simultaneously generating power. However, MFCs to be sustainable and scalable, they require significant technological operational improvements. This study aimed optimize the MFC process using Response Surface Methodology (RSM), which integrates modeling techniques, optimization methodologies, experimental design, analysis. RSM was applied evaluate interactions among three independent variables: working volume of wastewater, buffer's pH, bacterial consortia's inoculum size. Double-chambered were inoculated with various strains, including Pseudomonas stutzeri, Microbacterium algeriense, Bacillus stratosphericus. The results indicated that performance significantly influenced by between (i) buffer (ii) size, (iii) pH findings identified optimal conditions power generation hexavalent chromium (Cr6+) reduction as approximately 80% 6.9, 26% size consortia. A strong correlation model predictions confirmed model's accuracy in capturing factors. These demonstrated effectiveness optimizing provided valuable insights future development MFC-based systems.
