Abstract
In the present work, an experimental module for hydrogen purification based on nickel capillaries was fabricated. The module was tested by varying the temperature, the difference in the partial pressure of hydrogen on the feed and permeate sides of the capillaries. The maximum hydrogen flow obtained using a module based on 7 nickel capillaries with a wall thickness of 50 µm was 37.2 ml/min at a temperature of 900 оС and a hydrogen pressure of 0.9 atm. The stability of the hydrogen flow during the thermal cycling in the temperature range of 600–800 оС for 55 hours is shown.
