Combining phosphate species and stainless steel cathode to enhance hydrogen evolution in microbial electrolysis cell (MEC) [PDF]

, 2010
Microbial electrolysis cells (MEC) must work around neutral pH because of microbial catalysis at the anode. To develop a hydrogen evolution cathode that can work at neutral pH remains a major challenge in MEC technology.
