Benefits of technology

1. With the stress buffering unit, the hydrogen container is prevented from distortion and deformation that otherwise might be caused by stress out of volume expansion of the hydrogen storage materials during hy

Problems solved by technology

Consequently, the casing of the hydrogen storage device may deform due to the stress caused thereby.
In addition, absorption of hydrogen accompanies the exothermic effect, which raises the temperature in the device and in turn reduces the efficiency of absorption.
Hence,

Embodiment Construction

Referring to FIG. 1 through FIG. 3, the present embodiment shows a hydrogen storage device 100 for storing hydrogen gas. The hydrogen storage device 100 includes: a first casing 10, at least one hydrogen container 20, at least one stress buffering unit 30, and a second casing 40.

As shown in FIG. 2, the first casing 10 is formed therein with a first space 11 and thereon with a first opening 12. The first opening 12 allows the first space 11 to intercommunicate with the external environment, and allows hydrogen gas to be introduced into the first space 11 therethrough. The first casing 10 may include at least one depressed portion 13, which is formed by depressing the first casing 10 inward the first space 11. The depressed portion 13 may be shaped as a column.

The hydrogen container 20, which may be a top-opened annular container, is set inside the first space 11 for receiving a hydrogen storage material. Hydrogen gas is introduced into the first space 11 from the external environment...

Abstract

The present invention discloses a hydrogen storage device. The hydrogen storage device includes a first casing, at least one hydrogen container, at least one stress buffering unit, and a second casing. The hydrogen container is set inside the first casing. The stress buffering unit is set between the hydrogen container and the first casing. The second casing surrounds the first casing forming a second space to contain heat transfer media, thereby controlling the temperature of the hydrogen container. While the hydrogen storage materials loaded in the hydrogen container absorb hydrogen gas, the stress buffering unit can eliminate the stress caused by the volume expansion of the hydrogen storage materials so as to prevent the first casing from distortion and deformation. Thus, the hydrogen gas can be stored efficiently and safely.

Description

BACKGROUND OF THE INVENTION1. Technical FieldThe present invention relates to hydrogen storage devices, and more particularly, to a hydrogen storage device that stores hydrogen gas efficiently and safely.2. Description of Related ArtCurrently, hydrogen gas, which is used in fuel batteries, need to be stored in hydrogen storage devices. However, hydrogen gas is typically stored by means of hydrogen storage materials. One type of such hydrogen storage materials is metal hydride, which, in comparison with erstwhile approaches where hydrogen gas was liquefied under high pressure, is less likely bring about the problem of leakage and related dangers caused by mass hydrogen gas.Typically, existing hydrogen storage devices are made by filling hydrogen storage alloy powder in the device with a certain vacant space reserved for the expansion of the hydrogen storage alloy powder. When absorbing hydrogen gas, the hydrogen storage alloy powder expands in volume and the particles of the powder j...
