Abstract
An electrochemical reduction device comprises an electrode unit including an electrolyte membrane, a reduction electrode, and an oxygen evolving electrode; a power control unit that applies a voltage Va between the reduction electrode and the oxygen evolving electrode; a hydrogen gas generation rate measurement unit that measures a hydrogen gas generation rate F1; and a control unit that controls the power control unit so as to gradually increase the Va within a range that satisfies a relationship of F1≦F0 and V>V−acceptable potential difference (APD), when the potential at a reversible hydrogen electrode is V, the potential of the reduction electrode is V, the acceptable upper limit of the hydrogen gas generation rate is F0, and the APD is a potential difference that defines an upper limit of a potential difference between Vand V.
