摘要：

Kinetic rules of formation and decomposition of the hydrides derived from LaNi5-type compounds are determined. Comparison between LaNi5H6 and more stable hydrides such as LaNi5-χMχ (with M = Al, Cu, Ti) is made in terms of pressure, number and time of cycles. Measurements are performed by a differential volumetric device functioning under constant pressure, during hydrogen absorption and desorption. The influence on the kinetics and hydrogen capacities of the gaseous impurities contained in industrial hydrogen (H2O, CO2, CH4) is studied as a function of the number of cycles. It shows a good resistance to poisoning of the above mentioned compounds. © 1980.
