Solid hydrogen storage and desorption device and method based on temperature feedback regulation

Abstract

The invention discloses a solid hydrogen storage and desorption device and method based on temperature feedback regulation. During hydrogen storage, cooling liquid is injected into a liquid guide pipe, the cooling liquid circularly flows in the liquid guide pipe through a pump, a hydrogen storage material in a hydrogen storage bed body is cooled, and meanwhile, hydrogen is filled into a hydrogen storage tank body; hydrogen enters the hydrogen storage tank body after being filtered, and hydrogen storage is achieved at low temperature; during hydrogen desorption, the temperature in the hydrogen storage material is collected through the wireless temperature sensor, the hydrogen desorption speed and the hydrogen desorption temperature are determined according to needs, the temperature and the flowing speed of liquid in the liquid guide pipe are determined, and heating hydrogen desorption is achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogen storage and depletion, in particular to a device and method for solid hydrogen storage and depletion based on temperature feedback adjustment, which are used to provide power for hydrogen fuel electric vehicles. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Hydrogen storage methods mainly include high-pressure gas storage, low-temperature liquid storage and solid hydrogen storage. Among them, solid hydrogen storage is to store hydrogen in solid materials through physical adsorption or chemical reaction. [0004] At present, the solid hydrogen storage technology is not yet mature, and there are still many problems. For example, the conventional solid hydrogen storage system absorbs and discharges hydrogen by setting constant temperature conditions. When the hydrogen a...

Problems solved by technology

[0004] At present, the solid hydrogen storage technology is not yet mature, and there are still many problems. For example, the conventional solid hydrogen storage system absorbs and discharges hydrogen by setting constant temperature conditions. When the hydrogen absorption and desorption rate changes, the temperature cannot be adjusted in real time, and it is difficult to control the hydrogen storage material. The rate of hydrogen absorption and desorption makes it difficult to ensure that the temperature in the hydrogen storage tank reaches the optimum hydrogen absorption and desorption temperature to improve work efficiency
