HYDROGEN COMPRESSION MATERIAL, PREPARATION METHOD THEREFOR, AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2023/087949

Kind Code:

A1

Abstract:

Disclosed in the present invention is a hydrogen compression material, which has a structural general formula of Zr1-xTixFe1.7Cr0.2V 0.1, wherein x = 0.1-0.4. Further disclosed in the present invention is a preparation method for the hydrogen compression material. The method comprises the following steps: weighing zirconium, titanium, iron, chromium and vanadium metals according to the structural general formula, mixing and then placing same in a crucible, cleaning same with an inert gas, vacuumizing same, introducing the inert gas, and smelting same under arc conditions to obtain the hydrogen compression material. Further disclosed in the present invention is the use of the hydrogen compression material as a self-pressurization hydrogen storage material for a mechanical hydrogen compressor of a hydrogen-fueling station. By using waste heat generated by the mechanical hydrogen compressor, the hydrogen compression material absorbs 4-6 MPa hydrogen at room temperature and discharges hydrogen with a pressure of 6 MPa or more at 60°C. The hydrogen compression material of the present invention has the advantages of a large platform width and a large effective hydrogen compression amount within the working temperature range.
