High-pressure hydrogen storage bottle for fuel cell hydrogen energy automobile and manufacturing method of high-pressure hydrogen storage bottle

Abstract

The invention provides a high-pressure hydrogen storage bottle for a fuel cell hydrogen energy automobile and a manufacturing method of the high-pressure hydrogen storage bottle. The hydrogen storage bottle comprises an inner container, a bottle tail part and a wrapping layer, wherein the inner container comprises a container body and a bottle mouth part which are connected into a whole, the bottle tail part is fixed to the container body, the wrapping layer wraps around the outer surface of the whole container body, the manufacturing method comprises the following steps that S1, the inner container is machined; S2, the bottle tail part is machined and welded; S3, a wrapping layer of a carbon fiber material is wound; S4, the wrapping layer is formed; The high-pressure hydrogen storage bottle for the fuel cell hydrogen energy automobile and the manufacturing method of the high-pressure hydrogen storage bottle, have the beneficial effects that the wrapping layer can improve the compression strength of the high-pressure hydrogen storage bottle, so that the hydrogen storage capacity of the high-pressure hydrogen storage bottle is improved, the high-pressure hydrogen storage bottle is provided with the bottle mouth part and the bottle tail part structure, and the fixing structure of the high-pressure hydrogen storage bottle can be simplified through the bottle mouth part and the bottle tail part structure. By the adoption of the method, high-pressure gas is injected into the hydrogen storage bottle when the wrapping layer is formed, the wrapping layer can be pressed and formed in the heating process, the forming density of the wrapping layer is good, and therefore the compression strength of the hydrogen storage bottle is further improved.

Description

technical field [0001] The invention relates to the field of hydrogen storage devices for hydrogen energy vehicles, in particular to a high-pressure hydrogen storage bottle for fuel cell hydrogen energy vehicles and a manufacturing method thereof. Background technique [0002] With the improvement of people's living standards, the number of cars has gradually increased, and environmental issues have also received widespread attention. Therefore, the auto industry is actively promoting changes and promoting new energy vehicles. Among them, fuel cell hydrogen energy vehicle (hereinafter referred to as hydrogen energy vehicle) is an important embodiment of many new energy vehicles. It directly converts chemical energy into electrical energy through the reaction of hydrogen and oxygen to provide power, because of its high efficiency and near zero The advantages of emissions are generally believed to have broad development prospects by countries all over the world. The fuel of a...

Problems solved by technology

[0003] Due to the limitation of the strength of the metal material in the existing hydrogen storage bottle, the pressure of the hydrogen stored in it should not be too high, which will affect the hydrogen carrying capacity of the hydrogen energy vehicle, thus making it difficult for the cruising range of the hydrogen energy vehicle to meet the requirements. Increase the size of the hydrogen storage bottle to increase the hydrogen storage capacity of the hydrogen storage bottle, which will improve the quality of the hydrogen storage system and the vehicle, which is not conducive to the weight reduction of hydrogen energy vehicles, and will also increase the difficulty of installing the hydrogen storage bottle
