Abstract
  • Biohydrogen production via dark fermentation (DF) and microbial electrolysis cells (MEC) demonstrate great potential for sustainable hydrogen generation. In this study, DF and MEC were coupled as a hybrid reactor and evaluated using brewery wastewater. The effect of hydraulic retention time (HRT) and buffer concentration on reactor performance were assessed by current density and hydrogen production rate (HPR). Current density and HPR were highest at 48h HRT as compared to 60h, 36h, and 24h HRTs. When adjusting to 73mM from 146mM phosphate buffer solution, current density and HPR decreased by 22% and 28%, respectively. These results suggest 48 h HRT and 146 mM buffer concentration can be used to improve this reactor’s performance. Future experiments should be replicated over longer periods to ensure microbial communities are adjusted and the internal environment is stabilized.
