Description of the Invention: [Technical Field] The present invention relates to a hydrogen storage bottle structure having a metal porous foam material, and particularly to a hydrogen storage bottle structure having a metal porous foam material for storing hydrogen. [Prior Art] The main methods of storing hydrogen on the market include: gaseous high-pressure nitrogen storage method, liquid hydrogen storage method, hydrogen storage material hydrogen absorption and desorption method, and micro carbon tube hydrogen absorption and desorption method. The gaseous high-pressure hydrogen storage method and the liquid hydrogen storage method are only applicable to the fixed point a, and the hydrogen stored by the hydrogen storage material is equivalent to the solid hydrogen, and the required pressure I | /, mobility Good 'relatively applicable to transportation vehicles, the micro carbon tube hydrogen absorption method has the best gas storage efficiency', but it is still a commercial product in the research and development stage. ^However, the hydrogen storage material is mostly powdery. Although it has the advantages of large contact area, hydrogen absorption and hydrogen transfer, and good heat transfer efficiency, the disadvantage is that it is easy to make 5 wind materials when introducing or deriving hydrogen. The gas stream is carried away from the hydrogen storage vessel. This: the hydrogen storage material will be micronized after repeated use, and the gravity material will be easily deposited on the bottom of the hydrogen storage container. At this time, the volume expansion of the hydrogen storage material during the suction and release of the gas will be The force caused by the hydrogen storage container does not cause the gas to be damaged. In the second question, the heat transfer of the hydrogen storage material during hydrogen storage is also a large 丨t = hydrogen storage material, when hydrogen is rapidly reacted, a large amount of hydrogen is produced: = If the heat energy is not removed in time, the temperature rises. It will lead to a decrease in the hydrogen absorption rate, and it is true that the hydrogen storage material needs to provide sufficient heat energy, and the rate of release. Therefore, if the heat energy cannot be efficiently transported, Beijing 201126091 cannot accurately control the temperature of the hydrogen storage material, thereby affecting the fans of hydrogen storage and storage.
