Abstract: According to analysis of the main content (thermodynamics and dynamics) of the hydrogen storage properties for hydrogen storage material, an apparatus for measuring hydrogen storage properties was designed and assembled. The curve of the hydride dynamics under differently original pressure of hydrogen was measured in the constant container, and the curve of dehydride dynamics was measured through the method of double-drainning; the curve of PCT could be attained too. The properties of Mg-based (Mg-Ni-MnO2) composite prepared by mechanical milling was measured. The result indicates that, this design principle of the apparatus is reasonable; the hydriding and dehydriding kinetics properties of Mg-based composite prepared by mechanical milling are excellent. The PCT curve indicates that the hysteresis is little in hydriding and dehydriding, and the loss of energy is little too.

According to analysis of the main content (thermodynamics and dynamics) of the hydrogen storage properties for hydrogen storage material, an apparatus for measuring hydrogen storage properties was designed and assembled. The curve of the hydride dynamics under differently original pressure of hydrogen was measured in the constant container, and the curve of dehydride dynamics was measured through the method of double-drainning; the curve of PCT could be attained too. The properties of Mg-based (Mg-Ni-MnO 2) composite prepared by mechanical milling was measured. The result indicates that, this design principle of the apparatus is reasonable; the hydriding and dehydriding kinetics properties of Mg-based composite prepared by mechanical milling are excellent. The PCT curve indicates that the hysteresis is little in hydriding and dehydriding, and the loss of energy is little too.
