The traditional supply chain system of "building fixed hydrogen refueling stations similar to gas stations" is no longer able to support the development of the fuel cell industry at this stage in terms of "station planning", "hydrogen supply costs" and "continuous hydrogen refueling capacity". Creating a new path for hydrogen energy infrastructure construction is the key to whether hydrogen energy can develop steadily.

[0003] The current hydrogen supply system for hydrogen refueling stations is as follows: after hydrogen is purified, it goes through multiple links such as the bundle truck, unloading and refilling at the hydrogen refueling station.
