PURPOSE:To save the requisite power and to realize a high-efficiency reaction vessel by countercurrently circulating an oxidizing agent and a reducing agent on both sides of a diaphragm in the vessel. CONSTITUTION:Steam is introduced into a reaction vessel from an inlet 21 and reduced in a cathodic reaction chamber 23, and hydrogen is discharged from a product outlet 22. Meanwhile, carbon monoxide as a reducing agent is introduced from an inlet 24, oxidized in an anodic reaction chamber 26 and allowed to flow in the opposite direction to the steam. The oxygen extracted from steam on the cathode is passed through an electrolyte diaphragm 27 and used to oxidize CO on the anode. At this time, although the hydrogen concn. is increased in the cathodic reaction chamber 23, oxygen moves spontaneously since there is more than the equilibrium concn. of oxygen in the anodic reaction chamber 26 at all times. |
