Hydrogen sorption in LaNi4.,8A&,0,-H, at low temperatures

The LaNi,,, Al,,,-H, system has been investigated under atmospheres of hydrogen and inert gas (Ar) by differential scanning calorimetry (DSC). The effect was shown of hydrogen isothermal sorption temperature on the amount of hydrogen being sorbed and on sorption onset time. The dependence of partial molar enthalpy on hydrogen content in the intermetallic compound (IMC) was defined.
