Microbial electrolysis cell
A microbial electrolysis cell is a technology related to Microbial fuel cells . Whilst MFC's produce an electric current from the microbial decomposition of organic compounds, MEC's partially reverse the process to generate hydrogen or methane from organic material by applying an electric current...
