Performance and microbial ecology of methane-driven microbial fuel cells at temperatures ranging from 25 to 5 °C

The effluent of mainstream anaerobic processes is saturated with dissolved methane, representing a lost energy source and potent greenhouse gas emission if left unmanaged. This study investigated the impact of operational temperature on methane-driven microbial fuel cells (MFCs) designed for continuous operation to mitigate dissolved methane emissions in anaerobic effluents. Two bench-scale, single-chamber MFCs were operated sequentially at 25,...
