The storage and transportation of hydrogen is a key technology in the process of hydrogen energy utilization. At present, there are three main practical hydrogen storage methods: high-pressure gaseous hydrogen storage, low-temperature liquid hydrogen storage, and solid-state hydrogen storage. Among them, solid-state hydrogen storage technology uses the reaction of hydrogen and solid-state hydrogen storage materials to achieve hydrogen storage. Compared with other hydrogen storage methods, it has the advantages of high volume hydrogen storage density, low pressure, good safety, and high hydrogen purity. Therefore, solid-state hydrogen storage has become the most active hydrogen storage technology in hydrogen energy research.

[0003] When using solid hydrogen storage materials to store hydrogen, metal hydrides are mainly used to absorb hydrogen. This process is a chemical reaction process accompanied by a huge thermal effect. In order to ensure the safety of hydrogen storage, a bend is generally set in the solid hydrogen storage material, and a cooling medium is passed through the bend to achieve heat exchange, thereby absorbing the heat generated by the hydrogen absorption. Since the bend is installed in the heat exchanger, when the cooling medium contains impurities, the bend is easily blocked, thereby affecting the normal use of the heat exchanger.
