[0035] Such as figure 1 As shown, the present invention provides a hydrogen storage performance testing device suitable for materials with low hydrogen absorption equilibrium pressure, which includes a high-pressure gas introduction system, a high-vacuum gas reaction and a real-time observation system for hydrogen storage samples, a measurement system, a data acquisition system and Auxiliary test device.
[0036] The high-pressure gas introduction system is used to provide pressure-controllable high-purity hydrogen isotope gas to the high-vacuum gas reaction system. The high-pressure gas introduction system includes a ZrCo deuterium storage bed 3, which is connected with the ZrCo deuterium storage bed 3 through a main pipeline, for Standard tank 2 for gas buffer storage, mechanical pump 1 connected to the main pipeline for vacuuming the main pipeline, high-pressure valve components (VH1~VH20), thermocouple vacuum gauge 5, membrane Capacitance gauge 6 and precision pressure ga...
