A hydrogen storage device and its hydrogen fuel electric bicycle

Abstract

The invention discloses a hydrogen storage device and a hydrogen fuel electric bicycle thereof, belonging to the field of energy equipment. Including a bottle body, the inside of the bottle body is provided with a guide tube, the guide tube is installed on the central axis of the bottle body, and is fixedly installed along the guide tube according to a predetermined distance and a predetermined angle. A screen mesh divides the bottle body into a first cavity and a second cavity; the first cavity and the second cavity are arranged at intervals in sequence, and a solid hydrogen storage material is stored in the first cavity. In the present invention, by laying the solid hydrogen storage material on the first cavity, the accumulation of the solid hydrogen storage material is avoided, and the contact area between the hydrogen and the solid hydrogen storage material is increased, no matter in the hydrogen charging process or the hydrogen releasing process. It can achieve faster and more hydrogen charging and desorption, and give full play to the hydrogen storage performance of solid-state hydrogen storage materials.

Description

technical field [0001] The invention belongs to the field of energy equipment, in particular to a hydrogen storage device and a hydrogen fuel electric bicycle thereof. Background technique [0002] It is quite common to use hydrogen storage tanks as hydrogen storage devices. Whether it is a hydrogen fuel cell system or other products using hydrogen fuel cells, the supply of hydrogen is required. At present, hydrogen storage technologies can be mainly divided into three types: high-pressure gas, liquid hydrogen and hydrogen storage alloys. Among them, the high-pressure gas hydrogen storage method has higher energy, weight and density, but is larger in volume and less safe. Although the energy, weight and density of the liquid hydrogen storage method are also high, the liquefaction energy consumption is large, and an insulated storage tank must be used at the same time, which is generally suitable for large storage tanks; the energy, weight and density of the hydrogen storage ...

AI Technical Summary

Problems solved by technology

During long-term storage and transportation, solid hydrogen storage materials will accumulate on one side of the cavity instead of being evenly distributed. On the one hand, solid hydrogen storage materials need to release and absorb heat during hydrogen charging and decharging , so the pressure changes and temperature changes in different parts of the closed cavity will be quite different, which will affect the service life of the hydrogen storage bottle; Hydrogen storage properties of hydrogen storage materials
