Abstract

The invention discloses a device and a method for carrying out hydrogen storage on metal hydride by utilizing microwaves. The device adopts a microwave generating device and a hydrogen storage reactor which are coupled. The microwave generating device can provide a microwave effect for the hydrogen storage reaction above the hydrogen storage bed layer, and the hydrogen storage reactor mainly comprises a cylindrical hydrogen storage reactor shell, a hydrogen storage reaction bed layer, a hydrogen inlet valve and a hydrogen outlet valve and is used for providing a reaction place for the reaction of metal and hydrogen. In the device, the shape of the hydrogen storage metal is required to be an antenna-shaped, needle-shaped, thorn-shaped and other structures with tips or protrusions, so that the metal tip is induced to discharge, and then charges are enriched. The structure emits microwaves in the hydrogen absorption process to induce generation of active hydrogen anions, and the defect that hydrogen storage metal is difficult to store hydrogen quickly with low energy consumption is overcome. In the dehydrogenation process, active hydrogen anions are induced by microwaves to diffuse, hydrogen vacancies are formed, reductive dehydrogenation is excited, and the dehydrogenation temperature is reduced.

Description

technical field [0001] The invention belongs to the technical field of metal hydrogen storage performance optimization, and in particular relates to a device and method for metal hydride hydrogen storage using microwaves. Background technique [0002] Even under the ultra-high pressure of 70MPa, traditional high-pressure hydrogen storage still cannot meet the core indicators of mass and volume hydrogen storage density to meet the requirements of the international authority DOE for vehicle-mounted hydrogen storage. Different from high-pressure hydrogen storage, solid-state hydrogen storage has the advantages of high quality, volume density, safety, and economy. Under the same mileage, the volume of solid-state hydrogen storage is the smallest. It is included in my country's "Energy Technology Revolution Innovation Action Plan (2016-2030)" focus on action. Metal hydride hydrogen storage has the advantages of abundant sources, excellent reversible cycle, long life, mature prepa...
