Abstract

The pressure-composition isotherms of the LaNi₅-H₂ system are measured in full consideration of the thermal history. Once the temperature exceeds 343K, the two plateaus in the desorption process appear in any case. We also find an increase in the plateau slope and a decrease in the hydrogen storage capacity and the plateau pressure. These phenomena become more remarkable with elevation of the maximum temperature in activation and operation processes.
