Embodiment Construction
[0011] The present invention constitutes a hydrogen storage / hydrogen release system by hydrogen storage materials and an external electric field, the system has a multi-layer sandwich structure, wherein: the surface layer is made of molecular hydrogen H 2 Catalyst film 1 decomposed into atomic hydrogen H, such as pure Pt, pure Pd, Pt alloy or Pd alloy film, with a thickness of about 5-50 nm; the second layer is a pure Mg film or Mg-based low alloy film 2, with a thickness of about 5-500 nm, the alloy elements of Mg-based multi-element low-alloy thin film can be one or more of Nb, Ti, V, Ni, and the total alloy content is 0-20 wt.%. The third layer is electrostrictive material Thin film 3, with a thickness of about 5-500 nm, can be lead magnesium niobate (PMN), lead magnesium niobate-lead titanate (PMN-PT) or lead lanthanum zirconate titanate (PLNZT); the second and third layers of film. An electric field with variable direction and size is added to the multi-layer sandwich st...
