Summary:PURPOSE:To readily condense and remove water in hydrogen and to eliminate the necessity for a dryer in hydrogen purification using a hydrogen occluding alloy by exhausting another gas concentrated in space in a container charged with an alloy and taking out hydrogen through a re-condenser. CONSTITUTION:A cooling medium is fed to a container 2 charged with hydrogen occluding alloy granules 1 and the container 2 is cooled. When crude hydrogen containing a noncondensable gas such as N2, O2 or CO2 is fed from an induction pipe 8 to the container 2, hydrogen is occluded in the alloy 1, a noncondensable gas is concentrated between alloy granules 1 and water, a condensable gas, is condensed into liquid. After hydrogen is sufficiently introduced, the noncondensable gas between the alloy granules 1 is exhausted from a piping 9 to the atmosphere. Then, a heating medium is fed to the container 2, the container 2 is heated, hydrogen in the alloy 1 is taken out, condensed water is evaporated by heating, entrained with hydrogen and released. Hydrogen is recondensed by a re-condenser 13 put in a line, condensate is removed from a piping 11 and high-purity hydrogen is taken out from a piping 10.
