Abstract

The invention discloses a high vacuum-high pressure combined hydrogen storage property testing device for a low hydrogen absorption equilibrium pressure material. The device comprises a high pressure gas introduction system, a high vacuum gas reaction and hydrogen storage sample real-time observation system, a measurement system, a data acquisition system and an auxiliary testing device. The device disclosed by the invention has the advantages that the design is smart; the device can be used for acquiring kinetic data and thermodynamic data of a gas-solid reaction of a hydrogen storage material, especially the low hydrogen absorption equilibrium pressure material, in hydrogen absorption and desorption processes, and further observing the change of the sample surface appearance in situ in the reaction process at the same time, therefore the hydrogen storage properties of these materials are overall obtained, and the research demands on the fields of fusion energy and hydrogen energy are met.

Description

technical field [0001] The invention relates to the field of performance testing of hydrogen storage materials, in particular to a high vacuum-high pressure combined hydrogen storage performance testing device for low hydrogen absorption equilibrium pressure materials. Background technique [0002] With the development of new energy, especially fuel cell and fusion technology, the demand for hydrogen storage materials with excellent performance is becoming stronger and stronger. [0003] Ti, Zr, Sc and other materials have high volume hydrogen storage density, weak resistance to hydrogen isotopes (because of low atomic number), and good thermal stability (tritium dissociation pressure at room temperature <10 -4 Pa) and the ability to fix helium, which makes them the most promising tritium target materials for generating neutrons in thermonuclear fusion reactor experimental research. In addition, Ti, Zr, and Sc are also commonly used as getter materials in ultra-high vacu...
