[0002] As a clean, green energy source, hydrogen is widely used in fuel cell vehicles, making their widespread adoption a future trend. Hydrogen storage bottles are specialized containers for storing hydrogen. Their design and manufacturing must meet specific standards and requirements to ensure the safe storage and transportation of hydrogen. Hydrogen storage bottles can be divided into various types, depending on their purpose and type, such as high-pressure gaseous hydrogen storage bottles and solid-state hydrogen storage devices. Hydrogen filling equipment is specialized equipment used to fill hydrogen storage bottles. These devices typically include components such as hydrogen booster pumps and hydrogen filling machines to ensure that hydrogen can be safely and efficiently filled into the hydrogen storage bottles.

[0003] A search of the prior art reveals an "inflating device for inflating a hydrogen container" with publication number "CN208385534U."
