Description
Technical Field
The utility model relates to the technical field of thermal management of power generation equipment, in particular to a thermal management system of a solid-state hydrogen storage and power generation equipment system.
Background
At present, the hydrogen energy full-industry chain comprises three key links of hydrogen production, hydrogen energy storage and transportation and hydrogen energy utilization. Finding a safe, economical, efficient and feasible storage and transportation mode is a key for the full life cycle application of hydrogen energy. Storage and transportation of hydrogen energy includes storage of hydrogen and transportation of hydrogen energy.
The hydrogen storage technical requirements are safe, large in capacity, low in cost and convenient to take. At present, methods for storing hydrogen are mainly divided into low-temperature liquid hydrogen storage, high-pressure gaseous hydrogen storage and solid hydrogen storage. The low-temperature liquid hydrogen storage is to liquefy hydrogen and store the liquefied hydrogen in a low-temperature heat-insulating vacuum container, and the method has high hydrogen storage density per unit volume and relatively good safety, but needs to maintain extremely low temperature, so that the method has the advantages of high energy consumption, high cost and severe operation conditions. The high-pressure gaseous hydrogen storage technology is mature and is the most commonly used hydrogen storage technology in China at present, and the method has the advantages of mature technology, simple structure, high hydrogen charging and discharging speed, low cost and energy consumption, low volume hydrogen storage density and poor safety performance. The main application at present is as follows: a common steel bottle is stored in a small amount; the light high-pressure hydrogen storage tank is mainly used for hydrogen fuel cells.
The solid-state hydrogen storage technology utilizes the reaction of hydrogen and a solid-state hydrogen storage material to realize the storage of hydrogen, and the metal hydride hydrogen storage is the most promising solid-state hydrogen storage mode with faster development at present, namely, the metal hydride hydrogen storage is to store and release hydrogen by utilizing the metal hydride hydrogen storage material. Compared with other hydrogen storage modes, the hydrogen storage device has the advantages of large volume density, easy operation, convenient transportation, low cost, good safety and good reversible circulation.
The process of absorbing and releasing hydrogen by the solid hydrogen storage material is a chemical reaction process, namely, the heat release is needed when the hydrogen is absorbed, and the heat absorption is needed when the hydrogen is released. When solid hydrogen is stored and absorbed to release heat, if the released heat cannot be cooled in time, the hydrogen absorption rate is reduced until the hydrogen absorption is stopped; in contrast, when solid hydrogen storage releases hydrogen to absorb heat, if the solid hydrogen storage material cannot be heated in time to supply the required heat, the hydrogen release rate decreases until the release of hydrogen is stopped.

According to the utility model, the fuel cell and the metal hydride hydrogen storage tank are subjected to heat integration through a common water circulation loop, so that the waste heat of the fuel cell system is recycled, the necessity of using an external heater for the metal hydride is avoided, and the overall efficiency of the system is improved.
