Title:

HYDROGEN STORAGE MATERIAL

Document Type and Number:

Japanese Patent JP2005239454

Kind Code:

A

Abstract:

To provide a lightweight and low cost hydrogen storage material acting at a relatively low temperature and useful for an energy conversion material or the like.

The hydrogen storage material has a compound phase having a Ca3Si3H4 type crystalline structure as a main phase. A hydrogen storage apparatus is constituted by housing the hydrogen storage material in a vessel. A negative electrode material for nickel-hydride cell is constituted by containing the hydrogen storage material. Further, a heat storage apparatus, a chemical heat pump, a metal hydride sensor and a light transmittance-variable element are constituted by using the hydrogen storage material.
