Alloy for occlusion of hydrogen

An alloy of the composition represented by the formula, Mm.sub.1-x Ca.sub.x Ni.sub.5-y A.sub.y, wherein Mm stands for Mischmetal, A for one member selected from the group consisting of Al, Co, Cr, Fe, Mn, Si and Zn, x for a number within the range of 0.01 to 0.99 and y for a number within the range of 0.05 to 3 is useful for storage of hydrogen.

An alloy having a composition of the general formula, MmNi.sub.5-x A.sub.x-y B.sub.y, wherein Mm is misch metal, A is one member selected from the group consisting of Al, Cu, and Mn and B is one member selected from the group consisting of Al, Co, Cu, Fe, Mn, and Si, providing that both A and B do not represent one same compound, is useful for the occlusion of hydrogen.

A Mischmetal alloy of the general formula: MmNi.sub.5-x Cr.sub.x-y A.sub.y, wherein Mm stands for Mischmetal and A for Al, Co, Cu, Fe, Mn or Si, is highly useful as an alloy for the storage of hydrogen by occlusion.

Mischmetal alloy for storage of hydrogen

A device for the storage of hydrogen, comprising a container, two porous plates opposed parallelly to each other across a fixed distance and fastened to the inner wall of the container, heating/cooling members disposed one each outside the porous plates and separated by a fixed distance from the corresponding porous plates, and an alloy capable of storing hydrogen placed in the spaces formed between the porous plates and the heating/cooling members.

Device for storage of hydrogen

An alloy of the general formula, MmNi.sub.5-x A.sub.x (wherein, Mm stands for misch metal, A for one member selected from the group consisting of B, Ca, Cr, Cu, Fe, V, Zn and Si, and x for a numerical value in the range of from 0.01 to 2), which is useful for the occlusion of hydrogen.

An alloy comprising Mischmetal, cobalt and nickel is effectively usable for occlusion of hydrogen.
