Two mathematical models for the hydrogen storage properties of AB(2) type alloys

Two semi-empirical models have been applied to AB(2) hydrogen storage alloy s. One is concerned with the relation between formation enthalpy in hydridi ng and the atomic parameters of the alloys. The other is an expression for the PCT carves, which can be used for estimating some physical parameters o f these compounds and their hydrides, calculating unknown PC isotherms at g iven temperatures and finding the relationship of hysteresis to temperature and hydrogen concentration.
