Abstract

The invention relates to a hydrogen storage cylinder for an explosion-proof hydrogen fuel cell automobile and a manufacturing method thereof. The method comprises the following steps: 1 ultrahigh molecular weight polyethylene fibers impregnated with a surface active coupling agent is wound and pre-cured on the polyethylene liner of the hydrogen storage cylinder, and a first interface layer is formed on the plastic liner of the hydrogen storage cylinder; 2 a pressure sensor is attached to the surface of the first interface layer, then ultra-high molecular weight polyethylene fibers impregnated with low-temperature curing epoxy resin are wound on the first interface layer containing the pressure sensor and are pre-cured at the same time, and a second interface layer is formed on the plastic inner container of the hydrogen storage cylinder; and 3 the hydrogen storage cylinder obtained in the step 2 is cured for the first time, then carbon fibers impregnated with medium-temperature cured epoxy resin are wound on the surface of the obtained hydrogen storage cylinder, and finally secondary curing is conducted to obtain the hydrogen storage cylinder for the hydrogen fuel cell automobile, which is high in anti-explosion grade, light in weight, high in strength and good in safety.

Description

technical field [0001] The invention relates to the technical field of high-pressure gaseous hydrogen storage, in particular to a hydrogen storage cylinder for an explosion-proof hydrogen fuel cell vehicle and a manufacturing method thereof. Background technique [0002] The deepening of the global energy crisis, the continuous depletion of oil resources and the intensification of air pollution and rising global temperatures have made energy conservation and emission reduction the main direction of future automotive technology development. New energy vehicles such as fuel cells, as a new generation of transportation tools developed by the development of automobile technology, have incomparable advantages over traditional vehicles in terms of energy saving, emission reduction, and reduction of human dependence on traditional fossil energy.
