Through analysis of the hydriding/dehydriding process of hydrogen storage material, an apparatus for measuring hydrogen storage properties was designed and set up.

In this paper,the principle of absorbing/desorbing hydrogen and researching progress of some kinds of light metal-aluminum hydrides as hydrogen storage material are introduced.

Complex metal hydrides with AMH_4-type(A is Li,Na,K and M is B,Al,Ga)are considered as one of the most-potential hydrogen storage materials for its high gravimetric hydrogen content.

Nanotechnology can remarkably modify the hydrogen storage properties of hydrogen storage materials.

In this review our interest is focused mainly on the recent developments of reseach on rare earth functional materials,especially on rare earth phosphors and hydrogen storage materials.

Study of performances of hydrogen storage electrode modified with CoO;

Study of temperature propertes of hydrogen storage electrodes;

Analyses of degradable causes of hydrogen storage electrodes;

Kinetics performance of MH electrode was investigated.

The results showed that charge rate has obvious influence on charge electrode potentials and charge efficiency and discharge rate has obvious effect on discharge performance;electrochemical reaction impedance of the MH electrode decreased with the increase of depth of discharge,and increased when the DOD was above 8.

The experiment showed that the discharge rapacity of the MH electrode increased a little when 3% silver was added, but the amount of the gas escaped from the simulated cell was obviously reduced.
