Automatic control hydrogen absorption and desorption system and method for solid hydrogen storage material

Abstract

The invention discloses an automatic control hydrogen absorption and desorption system for a solid hydrogen storage material. The automatic control hydrogen absorption and desorption system comprisesa hydrogen filling pipe section, a hydrogen desorption pipe section and a stainless steel hydrogen storage tank. The stainless steel hydrogen storage tank comprises a stainless steel tank body and a tank body cover, and a plurality of metal baskets are arranged in the stainless steel tank body. A hydrogen filling hole and a hydrogen desorption hole are formed in the left end and the right end of the tank body cover respectively, and a temperature measuring hole is formed in the middle of the tank body cover. The hydrogen filling hole is connected with a hydrogen compressor through a hydrogen filling pipeline. The hydrogen desorption hole is connected with a hydrogen desorption pipeline. A thermocouple is inserted in the temperature measuring hole, and the lower part of the thermocouple extends into a central pipe. A heat preservation layer is arranged on the outer side of the stainless steel tank body, an electromagnetic heating coil is arranged in the heat preservation layer, and theheat preservation layer and the electromagnetic heating coil form an electromagnetic heating sleeve with a heat preservation function. The hydrogen compressor and the thermocouple are respectively connected with a computer control device. The automatic control hydrogen absorption and desorption system can achieve automatic control of temperature and hydrogen pressure, can be suitable for most solid hydrogen storage materials and has a wide application range.

Description

technical field [0001] The invention relates to the field of solid-state hydrogen storage, in particular to a system and method for automatically controlling hydrogen absorption and desorption of solid-state hydrogen storage materials. Background technique [0002] Hydrogen energy is a kind of clean energy. At present, the application of hydrogen energy is relatively mature in the world, but the storage and transportation of hydrogen are common technical bottlenecks. The pressure of foreign high-pressure gaseous hydrogen storage can reach 70MPa, and the pressure of domestic hydrogen storage cylinders can reach up to 35MPa. Although the hydrogen storage density has been increased, the requirements for the material of the cylinder are higher, and the risk factor is also higher. Cryogenic liquid hydrogen storage needs to be stored at -253°C. Both of these two hydrogen storage methods have technical and economic disadvantages. Solid hydrogen storage materials have become a favo...

AI Technical Summary

Problems solved by technology

Solid hydrogen storage materials have become a favored method of hydrogen storage due to their large hydrogen storage capacity and high safety. The medium is unevenly heated, the control effect of hydrogen absorption and desorption is poor, and the application range is narrow, etc.
