Description
This paper reports on thermophysical and kinetic properties of the LaNi5-H2 system that were investigated for the practical utilization of hydriding alloys. Measurements of the thermophysical properties were carried out by a transient hot-wire method along the P-C isotherms. The effective thermal conductivities of the system increase not only with an increase of hydrogen gas pressure but also in the plateau region with an increase of composition of metal hydride. The specific heats of the metal hydride increase with an increase in composition. The kinetic properties were measured under both isobaric and isothermal conditions. The derived intrinsic chemical reaction rates indicate a difference in the reaction mechanism between the absorption and the desorption processes
