Source: OSUResearchers at Oregon State University (OSU) have developed a new membrane-free microbial electrolysis cell (MEC) for the production of hydrogen gas from several types of biowaste including ordinary municipal sewage. The findings are reported in the journal Water Research.Microbial electrohydrogenesis is a similar process to water electrolysis, except that microbes at the anode decompose organic matter in CO2, electrons, and protons. A distinct advantage of the microbial system is the lower energy consumption compared t...
