Abstract

A three component alloy capable of reversible sorption of hydrogen having the chemical formula TiFe 1-x Mn x where x is in the range of about 0.02 to 0.5 and the method of storing hydrogen using said alloy.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A three component alloy capable of reversible sorption of hydrogen having the chemical formula TiFe 1-x  Mn x  where x is in the range of about 0.02 to 0.5. 
     
     
       2. The method of storing hydrogen comprising contacting a solid alloy of TiFe 1-x  Mn x  where x is in the range of about 0.02 to 0.5 with gaseous H 2  at a pressure above the dissociation pressure of the hydride. 
     
     
       3. The method of claim 2 in which the pressure of H 2  during contacting is at least twice the dissociation pressure of the hydride for the temperature during contacting. 
     
     
       4. The method of claim 3 in which the pressure of H 2  during contacting is about ten times the dissociation pressure of the hydride for the temperature during contacting. .Iadd. 
     
     
       5.  The product of the method of claim 2. .Iaddend.
