ABSTRACT:
Hydrogen gas from an generator (1) is occluded in a hydrogen recovery container (20), thereafter, in the initial stage during which hydrogen gas is released from the hydrogen recovery container (20), initially purged hydrogen gas containing much amount of impure gas is introduced from the hydrogen recovery container (20) to a gas tank (2) and saved therein, then, hydrogen gas having high purity released from a hydrogen absorbing alloy in the hydrogen recovery container (20) is refluxed to the generator (1), and this process comprising absorbing and releasing of hydrogen gas in the hydrogen recovery container (20) and saving in the gas tank (2) is repeated once or several times, successively, the hydrogen gas containing much amount of impure gas saved in the gas tank (2) is introduced in the hydrogen recovery container (20) and occluded therein, thereafter, in the initial stage during which hydrogen gas is released from the hydrogen recovery container (20), the hydrogen gas containing much amount of impure gas is discharged outside, then hydrogen gas having high purity released from the hydrogen absorbing alloy in the hydrogen recovery container (20) is refluxed to the generator (1).
