Hydrogen storage device employing piezoelectric thin film

摘要

The present invention relates to a hydrogen storage device capable of preventing hydrogen from permeating through the inner wall of a hydrogen storage container and preventing hydrogen embrittlement of the hydrogen storage container material. More specifically, the present invention relates to a hydrogen storage device, The hydrogen adsorption layer physically or chemically adsorbs hydrogen molecules to prevent hydrogen permeation and ionize hydrogen into positive ions. The surface of the thin film having piezoelectric characteristics is charged into a hydrogen storage container A dielectric polarization is generated by the pressure of the hydrogen gas and the surface positive charge is spontaneously formed to prevent hydrogen molecules ionized by the hydrogen adsorption layer from being diffused to the inner wall of the hydrogen storage container.
