Abstract
Key findings
- The system achieved a hydrogen production rate of 1.2 L/h, with a power density of 1.5 W/m².
- The microbial electrolysis cell (MEC) showed a higher efficiency compared to the microbial fuel cell (MFC) in hydrogen production.
- The pressure-retarded osmosis (PRO) module enhanced the system's overall performance by increasing the osmotic pressure and improving water utilization.
