Bio-electrochemical production of hydrogen and electricity from organic waste: preliminary assessment

نویسندگان

چکیده

Abstract This study investigated the performance of a novel integrated bio-electrochemical system for synergistic hydrogen production from process combining dark fermentation reactor and galvanic cell. The operating principle is based on electrochemical conversion protons released upon dissociation acid metabolites biological mediated by electron flow cell, coupling biochemical production. Accordingly, compartment also generates electricity. Four different experimental setups were designed to provide preliminary assessment identify optimal configuration further tests. Subsequently, cheese whey was implemented both in stand-alone process. achieved yield range 75.5–78.8 N LH 2 /kg TOC, showing 3 times improvement over Graphical abstract
