Novel hydrogen storage bottle used for hydrogen energy automobile

Abstract

The invention provides a novel hydrogen storage bottle used for a hydrogen energy automobile. The bottle comprises a flexible inner container, a rigid outer container, a first bottle plug, a second bottle plug, a hydrogen pipeline and an air pipeline. The top end and the bottom end of the rigid outer container are provided with openings, the first bottle plug and the second bottle plug are inserted in the openings in the top end and the bottom end correspondingly, a gas interlayer is formed between the flexible inner container and the rigid outer container, one end of the flexible inner container is provided with an air pipeline connector, a first through hole is formed in the first bottle plug, one end of the air pipeline is connected to the air pipeline connector of the flexible inner container, the other end of the air pipeline penetrates through the first through hole, and through an outer air compressor, air is guided into the flexible inner container. A second through hole is formed in the second bottle plug, one end of the hydrogen pipeline is arranged outside the rigid outer container, and the other end of the hydrogen pipeline penetrates through the second through hole tocommunicate with the gas interlayer. The novel hydrogen storage bottle has the beneficial effects that before the hydrogen bottle is used, rapid vacuum pumping is carried out, air residue in the hydrogen bottle is reduced, the storage hydrogen purity is improved, and meanwhile, the storage hydrogen in the hydrogen bottle can be effectively and completely sufficiently released to be used.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a novel hydrogen storage bottle for hydrogen vehicles. Background technique [0002] Hydrogen, together with solar energy and nuclear energy, is known as the three major new energy sources due to its high combustion efficiency and non-polluting products. For fuel cell vehicles, hydrogen storage should be dense, portable, safe and economical. At present, most fuel cell vehicles use high-pressure compression hydrogen storage method, so hydrogen energy vehicles must have hydrogen storage bottles during use. [0003] However, the hydrogen bottles used in the existing hydrogen energy vehicles, in the process of outputting hydrogen and filling hydrogen, cannot pump out the gas in the hydrogen bottles as clean as possible, which will lead to mixed gas when filling hydrogen. When other gases are pumped clean or when hydrogen is exported, all the hydrogen in the hydrogen bottle cannot...

[0003] However, the hydrogen bottles used in the existing hydrogen energy vehicles, in the process of outputting hydrogen and filling hydrogen, cannot pump out the gas in the hydrogen bottles as clean as possible, which will lead to mixed gas when filling hydrogen. When other gases are pumped clean or when hydrogen is output, all the hydrogen in the hydrogen bottle cannot be output, which reduces the utilization rate of hydrogen
