Description

technical field

[0001] The invention relates to the technical field of hydrogen storage, in particular to a plastic liner fiber fully-wound gas cylinder mouth structure. Background technique

[0002] Hydrogen energy is recognized as a clean energy source, and has been valued by people for its advantages such as abundant resources, high combustion value, cleanliness and renewable energy. With the rapid development of fuel cell and battery vehicle technology, safe and efficient hydrogen storage technology has become the key to the application of hydrogen energy.

[0003] The hydrogen storage method for vehicles uses gas cylinders to store hydrogen at high pressure and normal temperature. At present, there are four types of gas cylinders: all-metal cylinders, metal liner fiber hoop-wound gas cylinders, metal liner fiber-wrapped gas cylinders, and plastic liner fiber-wound gas cylinders. Winding cylinders. Among them, all-metal gas cylinders, metal liner fiber hoop-wound gas c...
