Etude de l'adsorption et de l'absorption de l'hydrogène formé par voie électrochimique sur différents métaux

Abstract : The hydrogen is known to penetrate very easily into numerous materials. This phenomenon can have dramatic consequences by causing flights(leaks) through the walls of containers or pipes, and also by weakening the structure of the material-host. The objective of this work is to obtain a better understanding of the processes taking place on the surface and inside the metal, in particular to study the relaxation of the adsorbed hydrogen, the distribution(broadcasting) of the hydrogen in a metallic membrane, and also to study the role of the constraint caused(provoked) by the insertion of the hydrogen in the palladium. Three typical metals, the iron, the palladium and the platinum will be used. Our approach(initiative) will consist in using a whole range of electrochemical methods in still diet(regime)
