Hydrogen containment materials

Diatomic hydrogen gas can adsorb and dissociate on metal surfaces to produce atomic hydrogen [1,2]. The subsequent dissolution and diffusion of atomic hydrogen into metals can have two consequences for the performance of a 

There are two additional considerations that we raise here as areas of potential concern, which are beyond the scope of this overview as they are related to the specific characteristics of the solid storage media. However, it is important to raise awareness of these issues. The first consideration is stress in the containment material induced by expansion of the solid storage media during absorption or desorption of hydrogen. Such stresses can, in principle, be quite large and should be considered in addition to the stress associated with the gas pressure. The second consideration is potential chemical

It is important to use the stable austenite alloys for hydrogen container materials, such as, FeNiCr stainless steel, FeNiCr strengthened with N and Mn stainless steel, /-precipitated strengthening superalloy. 

Very early, from the analysis of ignition, flame speed, and detonation velocity data, investigators realized that small concentrations of hydrogen-containing materials would appreciably catalyze the kinetics of CO—02. The H20-catalyzed reaction essentially proceeds in the following manner ... 

The use of a protective polymer film as barrier has been proposed. This barrier consists essentially of a thermoplastic poly(ester) resin, which is a homopolymer or copolymer adduct of an aromatic dicarb-oxylic acid in an active hydrogen-containing material. However, this poly(ester) resin copolymer has a poor compatibility with styrene resins. Thus, the protective polymer film lacks the desired regrind capability. 

JOLIOT-CURIE. IRENE 11897-195ft. A French nuclear scientist who won the Nohel prize for chemistry with her husband Frederick Joliet-Curie. Their joint work involved production of artiliciul radioactive elements by using t/-rays to bombard boron. They discovered that hydrogen-containing material when exposed to what they considered p rays would emit protons. Tliev were involved in many firsts they gave Ihe first chemical proof of aitillcial transmutation and of capture of alpha particles, and were the firsi to prepare positron emitter. Her career started with a Sc.D. at the Univ ersity of Paris, and included scores of honors and awards.
