Cross-reference art collection of alloys, or metallic compositions which are capable of taking up and releasing hydrogen for purposes of storage of hydrogen.
(1) Note. This class takes alloys, metallic compositions which take up hydrogen for storage no matter what the mechanism. Often the patent states that metal hydride is formed, but this is not always clear. This class thus takes hydrogen storage alloys in preference to Class 252, subclass 184 and Class 502, subclasses 400+ whether, or not the storage is stated to be by chemical reaction, or sorbtion.
