Solid-state hydrogen storage hydrogen source system and hydrogen energy vehicles

Abstract

Embodiments of the present invention provide a solid-state hydrogen storage hydrogen source system and a hydrogen energy vehicle, and relate to the field of hydrogen fuel storage equipment. The solid-state hydrogen storage hydrogen source system includes a hydrogen storage body, and a heat exchange medium pipeline, a hydrogen gas pipeline, and at least one alloy filling chamber for filling a hydrogen storage alloy are arranged inside the hydrogen storage body, and the heat exchange medium pipe The passage includes heat exchange pipelines arranged around the periphery of each alloy filling chamber, and the hydrogen gas passage communicates with each alloy filling chamber. It forms specific heat exchange medium pipelines, hydrogen gas channels and alloy filling chambers directly on the hydrogen storage body, so that the heat exchange medium pipelines, hydrogen gas channels and alloy filling chambers are integrated, and there is no need for additional components inside the system. Independent pipelines, thus effectively avoiding the occurrence of hydrogen gas caused by parts loosening due to vibration during the use of various parts of the system. In addition, the hydrogen energy vehicle has high safety and good stability, and at the same time, hydrogen filling is flexible.

Description

technical field [0001] The invention relates to the field of hydrogen fuel storage equipment, in particular to a solid-state hydrogen storage hydrogen source system and a hydrogen energy vehicle. Background technique [0002] The storage methods of hydrogen mainly include high-pressure gas storage, low-temperature liquid storage, and solid-state storage using hydrogen storage materials. Compared with high-pressure and liquid storage methods, the solid-state hydrogen storage method has the advantages of low hydrogen charging pressure, high volume storage density, good safety, and long-term storage. [0003] Due to historical reasons, automobile manufacturers often choose the high-pressure (>35MPa) gaseous storage method with higher technological maturity as the preferred hydrogen fuel storage system for their fuel cell vehicles. situation. However, although the high-pressure gaseous hydrogen storage technology has a simple route and fast hydrogen charging and discharging...

AI Technical Summary

Problems solved by technology

This method has improved the hydrogen absorption and desorption performance of the system very well, but it has also brought new problems: the connecting pipelines between the storage tanks and components generally use separate valve bodies and gas pipe connections, which will lead to During the driving process of the vehicle, the system is subject to constant vibration and loosening occurs.
