Metal hydride hydrogen storage. Metal hydrides, such as MgH 2, NaAlH 4, LiAlH 4, LiH, LaNi 5 H 6, TiFeH 2, ammonia borane, and palladium hydride represent sources of stored hydrogen. Again the persistent problems are the % weight of H 2 that they carry and the reversibility of the storage process. [16]

Metal hydride fuel cell systems have been integrated into microgrid systems at military bases for testing and evaluation. [17] Despite challenges, [ 18 ] the military maintains an active interest in fuel cells for a broad range of applications, including unmanned aerial vehicles , autonomous underwater vehicle , light-duty trucks , buses , and ...
Hydrides are important in storage battery technologies such as nickel-metal hydride battery. Various metal hydrides have been examined for use as a means of hydrogen storage for fuel cell-powered electric cars and other purposed aspects of a hydrogen economy. [11] Hydride complexes are catalysts and catalytic intermediates in a variety of ...
Proton flow batteries (PFB) integrate a metal hydride storage electrode into a reversible proton exchange membrane (PEM) fuel cell. During charging, PFB combines hydrogen ions produced from splitting water with electrons and metal particles in one electrode of a fuel cell. The energy is stored in the form of a metal hydride solid.
In general, complex metal hydrides have the formula M x M' y H n, where M is an alkali metal cation or cation complex and M' is a metal or metalloid.Well known examples feature group 13 elements, especially boron and aluminium including sodium aluminium hydride, NaAlH 4), lithium aluminium hydride, LiAlH 4, and lithium borohydride, (LiBH 4).

Some metal hydrides form when a metal complex is treated with hydrogen in the presence of a base. The reaction involves no changes in the oxidation state of the metal and can be viewed as splitting H 2 into hydride (which binds to the metal) and proton (which binds to the base). ML n x+ + base + H 2 ⇌ HML n (x-1)+ + Hbase +
