Organic hydride production device and method for reusing dragged water

Abstract

An organic hydride production apparatus includes an electrolysis tank having an anode electrode for oxidizing water in an anolyte La to generate protons, a cathode electrode for hydrating a substance α to be hydrated in the cathode liquid Lc with protons to generate an organic hydride β, and a diaphragm positioned between the anode electrode and the cathode electrode, the diaphragm moving protons together with produced water W from the anode electrode side to the cathode electrode side; an anolyte supply part for supplying the anolyte La to the anode electrode; a water separation unit for separating the produced water W from a catholyte Lc sent from the cathode electrode; and a water return unit for sending the produced water W separated by the water separation unit to the anolyte supply part.
