Thermophysicochemical properties of the LaNi5-H2 system are investigated for the practical utilization of hydriding alloys. The equilibrium pressure-composition isotherms are measured in full consideration of the thermal history. It is made clear that they are susceptible to the maximum temperature in operation processes. The kinetic properties are measured under isobaric and isothermal conditions. The results indicate the difference in reaction mechanism between the absorption and the desorption processes.
