A variety of factors contribute to the great current interest in l polynuclear metal hydride complexes. These include the novel geometries found in these systems and their usefulness as models for the bonding of hydrogen to metals, such as may occur in catalysis (i) or hydrogen-storage applications (2). A comprehensive review of metal hydride complexes, in which polynuclear species are included, has been published by Kaesz and Saillant (3). 

Properties of relevance for hydrogen storage applications, such as desorption enthalpies and weight and volume efficiencies, are summarized in Table 21. 

Different classes of porous materials possessing different structure and composition have been discussed for hydrogen storage applications. For all materials a... 

Even though the first metal hydride was discovered more than 100 years ago, intensive research on this class of materials is relatively new. Investigation of the hydrogen-metal interactions is very interesting from a fundamental point of view as well as for practical applications. In this chapter, we focus on the materials and properties that are especially important for hydrogen storage applications. 

In order to meet the requirements of a practical application, a metal hydride must first satisfy the thermodynamic requirements operation temperature and hydrogen pressure. As the entropy term of Eq. (1.11) is effectively the same for all compounds, this means that the heat of formation (AH) is the principal parameter of a given alloy for hydrogen storage applications. Unfortunately, first principles calculations of AH for ternary alloys are still lacking [47]. However, semi-empirical models can be applied for some systems and give useful physical insight on the hydride formation. 

Such hydrides based on intermetallic compounds are not only attractive for stationary hydrogen storage applications, but also for electrochemical hydrogen storage in rechargeable metal hydride electrodes, reaching capacities of up to 400 mAh g. They are produced and sold in more than a billion metal hydride... 

F anion-substituted systems are currently being investigated in several different national and international projects and the future will reveal the range of its usability for hydrogen storage applications.
