This product can absorb and desorb hydrogen at the room temperature and relatively low pressure, and more than 90% quantity of the hydrogen stored in it can be desorbed at relatively steady pressure in very steady hydrogen gas current. The hydrogen absorbing and desorbing pressure and the desorbing flow of the product depend on the users’ demand. Through the use of the product, the ordinary hydrogen can be purified into the ultra high pure hydrogen of 5 N purity .
