Abstract
An electrochemical reduction device includes an electrode unit, a power control unit, an organic material storage tank, a concentration measurement unit, a water storage tank, a gas-water separation unit, and a control unit. The electrode unit includes an electrolyte membrane, a reduction electrode, and an oxygen evolving electrode. The control unit controls the power control unit so as to satisfy a relation of V−V≤V≤Vwhen the potential at a reversible hydrogen electrode, the standard redox potential of the aromatic compound, and the potential of the reduction electrode are expressed as V, V, and V, respectively. Vis adjusted according to the concentration of the aromatic compound measured by the concentration measurement unit.
