Abstract

The invention relates to a manufacturing method of a metal hydride hydrogen storage tank, which includes processing of a tank body, processing of a flange cover, processing of a foamed copper element, preparation of hydrogen storage alloy powder, assembly and production of a hydrogen storage tank; the hydrogen storage The tank includes foam copper round cover, mat-type copper mesh, ferrule-type ball valve, air pipe, UJR joint, flange cover, bolts, O-ring, cooling fins, tank body, hydrogen storage alloy powder, foam copper cylinder, Copper foam discs, copper-water heat pipes, copper foam cylinders and other parts. The manufacturing method has high production efficiency, high yield, and low manufacturing cost. The metal hydride hydrogen storage tank prepared by the method has the advantages of simple structure, high space utilization rate, large hydrogen storage capacity, good sealing performance, and good heat and mass transfer performance. Excellent, fast hydrogen absorption and desorption, good long-term use safety, no rupture of the tank due to hydrogen absorption and expansion of hydrogen storage materials, no need for cooling medium, can be recycled many times, and low cost of use.

Description

technical field [0001] The invention relates to a method for manufacturing a metal hydride hydrogen storage tank, belonging to the technical field of hydrogen storage. Background technique [0002] As a safe and efficient hydrogen storage method, reversible solid-state hydrogen storage systems using hydrogen storage materials as the medium have attracted increasing attention. Compared with traditional high-pressure containers and liquid hydrogen storage methods, the reversible solid-state hydrogen storage system has many outstanding advantages: high volume hydrogen storage density; hydrogen source is desorbed from hydrogen storage materials, which can produce 99.9999% ultra-high purity hydrogen, especially suitable for fuel cells Use; suitable hydrogen discharge temperature and pressure improve the application safety of the hydrogen storage system and reduce energy consumption. The hydrogen storage material is used as the hydrogen storage medium. During the cycle of hydroge...

AI Technical Summary

Problems solved by technology

The hydrogen storage tank manufactured by this hydrogen storage tank manufacturing method has a low space utilization rate, too low filter aperture leads to large airflow resistance, and the flow rate of hydrogen charging and discharging is not fast enough, so a cooling medium needs to be specially introduced for cooling. High-density, complex-structured pipelines have high requirements for welding construction, which may easily cause impermeable welding or missing welding, and there are potential safety hazards for leakage. The structure of the entire hydrogen storage tank is complex, and assembly line production cannot be realized. The production efficiency is low and the cost is high.
