The surface reactivity must be maintained in any applications of hydrogen-metal systems with regard to the four different states of hydrogen, that is, hydrogen (H2), proton (H+), protium (H°), and protide (H ). The surface sensitivity and durability are reduced considerably when exposed to air, forming an inactive surface composed of oxides and hydroxides. Inactive surfaces are also formed from contact with impurities such as CO, CO2, H2S, NO2 N2 and others [214].

In the following figures are given data illustrating these types of behaviour. The maxima are not always sharp as in the Hg-B-Pd system, nor are they always so well defined. The curve of log (solubility) against 1/T in Fe-Mo alloys, as Fig. 42 shows for many hydrogen-metal systems, is linear (49). 

In this field some very thorough studies have been made for hydrogen-metal systems, especially by Lombard and Eichner(69), Smithells and Ransley (60) and Post and Ham(6i). Even for hydrogen-metal systems, however, the interpretation of the permeation rate-pressure isotherms is not clear. Studies of glass, crystal, and organic membrane permeability have shown that two possible permeation rate-pressure relationships emerge ... 

In the practical experiments, the influences of some essential and/or experimental factors for the reaction kinetics of hydrogen-metal systems have to be considered. The chemical potential of the surrounding hydrogen gas changed by pressure variation due to the reaction, the local heat generation caused by the formation of solid solution or hydride. The reaction mechanism (order) is also important in order to understand the essential kinetic properties of the reaction. As the experimental factors, the stabilities of the temperature and pressure in the experimental systems and/or the sample conditions, which are quality, quantity, particle size, porosity, thermal conductivity, and so on, also affect the kinetic properties. Thus, the reaction models and experimental situations should be considered in order to discuss the essential kinetic properties about the chemical reactions.

Research on hydrogen absorption in metals has been stimulated for some considerable time now by the possibility of using hydrogen-metal systems as chemical and nuclear energy carriers. We recall here some of the prominent features of hydrogen metal systems ...
