The characteristics of phase change materials is with the temperature change from one phase to another phase change, can absorb or release a large number of latent heat, and the temperature of the material itself in front of the phase transformation completed almost unchanged, it is actually a constant energy storage.
After the completion of phase change material filling, sealed and covered with a layer of plastic film, and then covered with a layer of gypsum board in each galvanized steel flat box, so that the completion of phase change materials package.

The process allows for material selection flexibility to optimize materials for all components with respect to performance, as shown in Fig. 1 [2].
Commonly, the sintered materials can be the Si-C-Cu-Mg-Si-Fe and Fe-C-P-Ni-Cr-Mo alloy etc [1,7].
Ideally, further research work should focus on accurate joint design and develop new composite materials for connection strength.

The interpretation of data obtained by the PLEPS technique was significantly supported by the scanning electron microscopy (SEM) data obtained at the Institute of Materials Science (Faculty of Materials Science and Technology, STU).
Therefore, additional destructive or non-destructive techniques should be used to give us a complementary view on the examined materials.

Introduction Alloy materials containing rare earth elements are prospective materials for hydrogen storage because of its excellent performances, such as mediate pressure of hydrogen decomposition, low equilibrium pressure for hydrogen adsorption, rapid response, as well as special insensitive property for impurities.
Relevant crystal structure and electrochemical performance of magnesium-based hydrogen storage materials have been investigated in details [10-12].
