Description

Technical Field

[0002] The solid-state hydrogen storage tank is the most basic unit of the solid-state hydrogen storage device. Its performance and life are the key to the reliable operation of vehicle-mounted hydrogen storage systems, large-scale energy storage stations and hydrogen refueling stations. The advantage of solid-state hydrogen storage tanks is that they can store a large amount of hydrogen at a lower pressure and in a smaller space, and can release hydrogen continuously and controllably under mild conditions. This allows solid-state hydrogen storage tanks to be efficiently coupled with renewable energy power generation and hydrogen production, providing broad prospects for the application of hydrogen energy.
