Two semi-empirical models have been applied to AB2 hydrogen storage alloys. One is concerned with the relation between formation enthalpy in hydriding and the atomic parameters of the alloys. The other is an expression for the PCT curves, which can be used for estimating some physical parameters of these compounds and their hydrides, calculating unknown PC isotherms at given temperatures and finding the relationship of hysteresis to temperature and hydrogen concentration.
