| 摘要 |
The present invention relates to a hydrogen storage device and, more specifically, to a hydrogen storage device, capable of increasing absorption and desorption speeds of hydrogen by increasing heat conductivity, and minimizing the transformation of a container by buffering pressure, applied into the container. According to the present invention, with a structure in which the expansion and contraction of a hydrogen storage alloy have flexibility, the efficiency of thermal delivery into the hydrogen storage tank is not influenced by the expansion and contraction of the hydrogen storage alloy in order to increase the absorption and desorption speeds of hydrogen. Moreover, when the hydrogen storage alloy expands by reacting to the hydrogen due to foamed metal, pressure to the hydrogen storage container is buffered and a reaction area between the hydrogen and the hydrogen storage alloy is increased, thereby improving efficiency of hydrogen storage. A problem about heat delivery, caused by an empty space formed by the contraction of the hydrogen storage alloy, is solved and a hydrogen shear rate is improved to easily discharge the hydrogen. |
