As shown in FIG. 1 , the liquid hydrogen storage tank 100 according to the present invention mainly includes a tank body 10 , a first catalytic device 20 and a second catalytic device 30 . Among them, the tank body 10 serves as the main structure of the liquid hydrogen storage tank 100 . Preferably, the tank body 10 is configured as a hollow square structure. In this way, the hydrogen storage structure is more stable and easier to install than the traditional bottle-shaped hydrogen storage structure, and its size and proportion can also be flexibly changed according to the needs of the use scenario. The inside of the tank 10 is filled with a liquid hydrogen storage substance 11 . The first catalytic device 20 and the second catalytic device 30 are both disposed inside the tank 10 .

Among them, the rope 51 can connect the second accommodation compartment 31 in series, thereby reasonably restricting the movement path of the second accommodation compartment 31. In this way, the second storage compartment 31 can be effectively dispersed within the liquid hydrogen storage tank 100 , thereby increasing the coverage area of the second storage compartment 31 on the liquid hydrogen storage material, thereby accelerating the removal of the hydrogen storage material 11 from the liquid hydrogen storage tank 100 . The separation of the released hydrogen from the liquid hydrogen storage material stabilizes the amount of hydrogen input into the hydrogen energy vehicle, thus solving the problem of battery life of the hydrogen energy vehicle. In this embodiment, at least one fixed base 50 is provided; and at least one rope 51 is provided.

The regulator 511 is configured to flexibly change the distance between adjacent second storage chambers 31 according to the needs of the use scenario, so that the second catalyst 32 can be in the best catalytic environment in the hydrogen storage material 11, thereby improving The economy of the liquid hydrogen storage tank 100 is improved.

In this way, the second storage compartment 31 can be effectively dispersed within the liquid hydrogen storage tank 100, thereby increasing the coverage area of the second storage compartment 31 on the liquid hydrogen storage material.
在该实施例中，由于一条绳索51只对应于一个第二容纳仓31，使得每个第二容纳仓31都具备独立的运动范围，从而让第二容纳仓31能够在储氢物质11中更加有序的完成催化工作，进而加快了从储氢物质11所释放的氢气与液态储氢物质的分离，使输入氢能源汽车的氢气量能够趋于稳定，由此解决了氢能源汽车的续航问题。In this embodiment, since one rope 51 only corresponds to one second accommodation chamber 31 , each second accommodation chamber 31 has an independent movement range, so that the second accommodation chamber 31 can move more easily in the hydrogen storage material 11 . The catalytic work is completed in an orderly manner, thereby accelerating the separation of the hydrogen released from the hydrogen storage material 11 and the liquid hydrogen storage material, so that the amount of hydrogen input to the hydrogen energy vehicle can become stable, thus solving the battery life problem of the hydrogen energy vehicle. .

In this way, the first catalyst 22 and the second catalyst 32 can be kept intact in the first storage compartment 21 and the second storage compartment 31 respectively. In addition, due to the solid structure, the contact area between the catalyst and the hydrogen storage material 11 is effectively increased, thereby accelerating the release speed of the hydrogen storage material 11 and the hydrogen gas released from the hydrogen storage material 11 and the liquid hydrogen storage. The speed of separation of substances.
