The hydriding/dehydriding thermodynamic properties of the slurry system formed by suspending La-rich mischmetal nickel hydrogen storage alloy (MlNi5) in Benzene (C6H6) were investigated. The pressure-composition isotherms for both the alloy powder and the slurry suspended with MlNi5 were measured at several temperatures(10, 20, 30, 40 ℃). The standard enthalpy of formation ΔH° and standard entropy of formation ΔS° for the alloy powder with and without benzene were determined respectively. The experimental results show that the values of ΔH° and ΔS° for the hydriding reaction of hydrogen storage alloy (MlNi5) of the slurry system and the gas-solid system are all very close.
