PURPOSE:To produce a hydrogen-containing mixed gas having a hydrogen concentration of high industrial value, by removing hydrogen at the anode of an electrochemical hydrogen-separation apparatus using an ion exchange resin, and utilizing the residual gas left after the separation of hydrogen. CONSTITUTION:An ion exchange resin membrane 1 prepared by introducing sulfonic acid group to a perfluorocarbon resin base is integrated at one surface with the cathode 2 and at the other surface with the anode 3, and is furnished with the charge collectors 4, 5 for the anode and cathode, the terminal plates 6, 7 for the anode and cathode, and the cell frame 8. The primary mixed gas having relatively high H2 concentration and humidified to the saturated state is introduced into the cell through the gas inlet 9, and a DC current is passed through the terminal plates 6, 7. H is ionized at the electrode 3, and H2 is generated at the electrode 2. The generated H2 is discharged through the outlet 10. The secondary mixed gas having relatively low hydrogen concentration and left after the partial consumption of H2 at the electrode 3 is discharged through the outlet 11. Since the H2 concentration of the objective gas is a function of the H2 concentration of the primary mixed gas, the rate of feeding and the operating electrical current, the variables are controlled to attain a constant H2 concentration. |
