A molecular weight of less than CaCl 2, use occlusion weight of NH 3 per 1g in a state where pressurized to several atmospheres at room temperature or several tens of degrees below the temperature, the more material than absorbing the weight of CaCl 2 in the same conditions An ammonia storage / release material was provided. The material for storing and releasing ammonia is selected from metal or ammonia borohydride (borohydride compound) LiBH 4 , NaBH 4 , Mg (BH 4 ) 2 , Ca (BH 4 ) 2 and NH 3 BH 3. Made of at least one material. The substance, LiBH 4, NaBH 4, is preferably either NH 3 BH 3, more preferably NaBH 4 or NH 3 BH 3. [Selection figure] None |
