Ammonia manufacturing apparatus and ammonia manufacturing method

An ammonia manufacturing method comprising:

• supplying a first electrolytic solution into a first electrolytic bath of an electrochemical reaction unit and supplying a second electrolytic solution containing nitrogen, an ammonia producing catalyst, and a reducing agent into a second electrolytic bath of the electrochemical reaction unit, the electrochemical reaction unit comprising the first electrolytic bath, an oxidation electrode disposed in the first electrolytic bath, the second electrolytic bath, a reduction electrode disposed in the second electrolytic bath, and a diaphragm provided between the first electrolytic bath and the second electrolytic bath;
• reducing the nitrogen by the ammonia producing catalyst and the reducing agent in the second electrolytic bath to produce ammonia, and oxidizing the first electrolytic solution at the oxidation electrode in the first electrolytic bath and reducing the reducing agent oxidized due to the production of the ammonia in the second electrolytic bath at the reduction electrode, by supplying electric power from a power supply to the oxidation electrode and the reduction electrode;
• dissolving nitrogen in the second electrolytic solution so as to sustain a reduction reaction of the nitrogen in the second electrolytic bath;
• and
• separating the ammonia from the second electrolytic solution to produce the ammonia.
