dc.description.abstractThis study investigates the potential opportunities of hydrogen evolution treating landfill leachate in a set of two microbial electrolysis cells (MEC-1 and 2) under 30 C and 17 ± 3 C temperatures, respectively. The system achieved a projected current density of 1000e1200 mA m 2 (MEC-1) and 530e755 mA m 2 (MEC-2) coupled with low cost hydrogen production rate of 0.148 L La 1 d 1 (MEC-1) and 0.04 L La 1 d 1 (MEC-2) at an applied voltage of 1.0 V. Current generation led to a maximum COD oxidation of 73 ± 8% (MEC-1) and 65 ± 7% (MEC-2) with 100% energy recovery. The system also exhibited a high hydrogen recovery (66e95%), pure hydrogen yield (98%) and tremendous working stability during two months of operation. Electroactive microbes such as Pseudomonadaceae, Geobacteraceae and Comamonadaceae were found in anodophilic biofim, along with Rhodospirillaceae and Rhodocyclaceae, which could be involved in hydrogen production. These results demonstrated an energy-efficient approach for hydrogen production coupled with pollutants removal. This research was supported by the regional government ‘Junta de Castilla y León, Consejería de Educación’ and Ana Sotres thanks for the postdoctoral contract associated with project reference: LE060U16, co-financed by FEDER fundses_ES
