Boosting hydrogen production from fermentation effluent of biomass wastes in cylindrical single-chamber microbial electrolysis cell.

Microbial electrolysis cells (MECs) are considered as green technologies for H production with simultaneously wastewater treatment. Low H recovery and production rate are two key bottlenecks of MECs fed with real H fermentation effluent of biomass wastes. This work established a 1 L cylindrical single chamber MEC and enriched electroactive anodic biofilms from cow dung compost to overcome the bottlenecks.
