ELECTROCHEMICAL REDUCTION DEVICE AND METHOD FOR MANUFACTURING HYDRIDE OF AROMATIC COMPOUND

摘要

An electrochemical reduction device includes an electrode unit, a power control unit, a concentration measurement 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 such that a current value I flowing through the reduction electrode and the oxygen evolving electrode satisfies Equation, I≦Imax (C). In Equation, a maximum current value Imax (C) is defined according to a concentration C of an aromatic compound obtained by the concentration measurement unit such that Faraday efficiency is to be a predetermined value or more.
