Electricity generation by a baffle-chamber membraneless microbial fuel cell

摘要: Microbial fuel cells (MFCs) for organic waste and wastewater treatment represent innovative technologies pollution control energy generation. The research reported here considers the influence of reactor configurations designed to mitigate impact oxygen transport on electricity generation by a baffle-chamber membraneless MFC. was constructed reduce mixing in vicinity cathode facilitate thick (>1 mm) biofilm formation adding anaerobic biomass/sludge (4330 ± 410 mg COD L−1), resulting an overall coulombic efficiency more than 30% at glucose concentrations ranging from 96 960 mg COD L−1, compared previously efficiencies <10% completely mixed Efficiencies absence sludge dropped 21.2 ± 3.7%, suggesting that importance pH buffering provided biomass improving electron anode. However, itself very limited power (approximately 0.3 mW m−2) primarily associated with degradation (e.g., 129 ± 15 mW m−2).
