Title:
HYDROGEN PURIFICATION DEVICE AND HYDROGEN PURIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/187475
Kind Code:
A1
Abstract:
Provided are a hydrogen purification device and a hydrogen purification method whereby hydrogen having a high purity can be purified at a high yield from a starting gas. The hydrogen purification device 1 comprises: a starting gas source 9 that supplies a starting gas, said starting gas containing hydrogen molecules and/or a hydride, to a discharge space 3; a plasma reactor 2 that defines at least a part of the discharge space 3; a hydrogen flow channel 5 that is connected to the discharge space 3 and leads out purified hydrogen from the starting gas source 9; a hydrogen separation membrane 4 that partitions the discharge space 3 from the hydrogen flow channel 5, defines at least a part of the discharge space 3 by one surface thereof and defines at least a part of the hydrogen flow channel 5 by the other surface thereof; an electrode 7 that is positioned outside the discharge space 3; and an adsorbent 6 that is filled in the discharge space 3 and adsorbs the starting gas. In the hydrogen purification method according to the present invention, the starting gas is adsorbed by the adsorbent 6 in the discharge space 3. Hydrogen molecules, which have been desorbed from the adsorbent 6 by discharge, are allowed to penetrate through the hydrogen separation membrane 4 and led out into the hydrogen flow channel 5.
