Applying multiple bio-cathodes in constructed wetland-microbial fuel cell for promoting energy production and bioelectrical derived nitrification-denitrification process

A multiple bio-cathodes constructed wetland-microbial fuel cell (CW-MFC) system, aiming for higher power production and therefore the improved N removal, was investigated in this study. As the bio-cathode number increased from 1 to 3, the energy losses on both anode and cathode showed a significant decrement (from 97.85 mV to 46.09 mV for anode and from 221.5 mV to 45.89 mV for cathode, respectively). Accordingly, the maximum power density of...
