N2 - The hydrogen sorption properties of the hydrides of the Laves phase compounds GdB2 (B=Mn, Fe, Co, Ni, Rh, Ru) and LaRh2 have been studied at various temperatures in the pressure range up to 20 atm. Hydrogen absorption in LaB2 (B=Ru, Pt, Ir, Al) and GdB2 (B=Ir, Al) was measured in the pressure range up to 70 atm. A model that calculates the prefered interstitial sites occupied by the hydrogen is presented for the AB2 compounds. A gradual decrease of the hydrogen absorption capacity is observed for the GdNi2 and GdCo2 compounds after several absorption-desorption cycles. The hydrogen-cycled GdRh2 exhibited a change in its thermodynamic properties.
