- ... BACKGROUND: Bioelectrochemical systems (BESs) are capable of recovery of metals at a cathode through oxidation of organic substrate at an anode. Recently, also hydrogen gas was used as an electron donor for recovery of copper in BESs. Oxidation of hydrogen gas produced a current density of 0.8 A m‐² and combined with Cu²⁺ reduction at the cathode, produced 0.25 W m‐². The main factor limiting curr ...
