Reduced internal resistance of microbial electrolysis cell (MEC) as factors of configuration and stuffing with granular activated carbon

With limited external applied voltage,the microbial electrolysis cell (MEC) could produce hydrogen by exoelectrogenic microorganisms. The present study revealed that a cubiod-shaped chamber effectively reduce the distance between electrodes and thereby reduce the internal resistance of the entire cell.With 0.6 volt of applied voltage,the cuboid MEC had a columbic efficiency of 33.7%,much higher than that achieved in the H-shaped MEC test (ca.15%) of comparable size.Filling the anode chamber with granular activated carbon further enhanced the columbic efficiency to 45%. The corresponding hydrogen conversion rate could reach 35%.
