Embodiment 1
[0029] The non-hydrogen-absorbing foamed metal substrate in the metal hydride hydrogen storage device adopts a foamed aluminum substrate with a porosity of 91% and a thickness of 15 mm. The cylindrical shell of the hydrogen storage device is made of aluminum alloy with an inner diameter of 80 mm; the hydrogen storage alloy is a rare earth hydrogen storage alloy Mm 0.8 Ca 0.2 Ni 5 , where Mm is a mixed rare earth metal. Mm 0.8 Ca 0.2 Ni 5 The alloy is crushed to form a powder with a particle size not greater than 0.2 mm; then Mm 0.8 Ca 0.2 Ni 5 Mix the alloy powder with a 3% PVA aqueous solution (the amount added is one-tenth of the weight of the hydrogen storage alloy powder) to form a paste, then smear it into the pores of the foamed aluminum substrate, and heat it at 30 ° C. Completely dry to form a hydrogen storage material sheet; then cut the dried hydrogen storage material sheet into a disc with an outer diameter of 80 mm, and make a circular hole with a diameter ...
