An object of the present invention is to enable filling a hydrogen storage alloy uniformly and easily at the time of filling the hydrogen storage alloy. The invention relates to a method for filling a hydrogen storage alloy including, when the hydrogen storage alloy that has been made as a resin composite material by mixing hydrogen storage alloy particles or powder with a resin and carbon fiber is filled into a tank, vibrating the tank at a predetermined frequency to adjust a filling ratio of the hydrogen storage alloy in the tank.

The composition for hydrogen storage is a composite of MgH.sub.2 powder and a metallic glassy Zr.sub.70Ni.sub.20Pd.sub.10 powder. Preferably, the metallic glassy Zr.sub.70Ni.sub.20Pd.sub.10 powder forms about 5 wt % of the composition for hydrogen storage. The composition for hydrogen storage is prepared by mixing MgH.sub.2 powder and Zr.sub.70Ni.sub.20Pd.sub.10 powder to form a mixture, and then performing reactive ball milling on the mixture. Preferably, the reactive ball milling is performed under 50 bar of hydrogen gas atmosphere for a period of 50 hours.

This disclosure refers to a method for the synthesis of polymers with weight average molecular weights greater than 50,000 g/mol, chemically inert, with a minimum decomposition temperature of 425 C., and a main chain composed only of carbon-carbon bonds, which contain structures of the type of naphthalene, phenanthrene, anthracene, pyrene, carbazole or any other where two or more aromatic rings of six carbon atoms of the benzene-type are fused, which may or may not contain aromatic heterocycles. In addition, the polymers obtained from the present disclosure may or may not contain fluorine atoms in their structure. The synthesis described here is carried out by means of polycondensation between a polycyclic aromatic compound and a compound with a carbonyl group in its structure in a strong acid medium.

The present invention disclosures a magnesium@high-sulfur coke hydrogen storage material and a preparation method thereof. The method comprises: ball milling magnesium powder with high-sulfur coke in an inert atmosphere to obtain a mixture; subjecting the mixture to pressing to form a pressed tablet, followed by melt infiltration in an inert atmosphere to obtain an infiltrated product and a magnesium vapor; and subjecting the infiltrated product to adsorption and condensation of the magnesium vapor to obtain the magnesium@high-sulfur coke hydrogen storage material. The prepared magnesium@high-sulfur coke has low plateau temperature, high hydrogen storage capacity, fast hydrogen absorption/desorption rate, and other advantages.
