This product can absorb and desorb hydrogen at the room temperature and relatively low pressure. This product can absorb and desorb hydrogen at the room temperature and relativelylow pressure, and more than 90% quantity of the hydrogen stored in it can be desorbedat relatively steady pressure in very steady hydrogen gas current. The hydrogenabsorbing and desorbing pressure and the desorbing flow of the product dependon the users' demand. The typical value of the product is, 1.2wt. % as the hydrogen storage density perunit weight, and 30kgH 2 /m 3. As the hydrogen storage density per unit volume.Through the use of the product, the ordinary hydrogen can be purified into theultra high pure hydrogen of 6N purity, which indicates that the technology of theproduct has reached the international advanced level. The specifications of the product are defined with the amount of the desorbing hydrogenin standard state, which is from several liters to several hundreds of cubicmeters. The shape of the product is generally cylindrical, and it can be adjustedwith the users' demand.
