Embodiment 1

[0139] A hydrogen refueling station is a multi-stage hydrogen filling system composed of a hydrogen storage bottle group trailer, a hydrogen storage bottle group on the station, and a hydrogenation machine; its technical characteristics are:

[0140] There are multiple hydrogen storage bottles on the trailer of the hydrogen storage bottle group and the hydrogen storage bottle group on the station. There are pressure sensors and valves on the pipeline of each hydrogen storage bottle. The gas outlet pipeline with hydrogen mass meter, pressure sensor, valve and hydrogenation gun on the hydrogen machine constitutes a multi-stage hydrogen injection system;

[0141] The trailer of the hydrogen storage bottle group is filled with hydrogen above the rated pressure and connected to the multi-stage hydrogen filling system, and the fuel cells are filled with hydrogen through the hydrogenation machine step by step in the order of low, medium and high pressure until the rated pressure is fu...

Abstract

A hydrogen refueling station is composed of a hydrogen storage bottle group trailer and multiple hydrogen storage bottles on the station. Each hydrogen storage bottle has a pressure sensor and a valve on the pipeline, and its pipelines are used as a hydrogenation machine in parallel. The inlet pipeline of the hydrogenation machine and the outlet pipeline with a hydrogen mass meter, pressure sensor, valve, and hydrogenation gun on the hydrogenation machine constitute a multi-stage hydrogen filling system; The hydrogen filling system, according to the order of low, medium and high pressure hydrogen storage bottles, fills the fuel cells with hydrogen through the hydrogenation machine step by step until the rated pressure is full; when the hydrogen in the hydrogen storage bottle group on the station is used up, use The hydrogen on the trailer of the hydrogen storage bottle set will be filled until the high-pressure hydrogen (hydrogen above the rated pressure) on the trailer of the hydrogen storage bottle is used up, and the remaining medium and low-pressure hydrogen (hydrogen below the rated pressure) will be filled into the storage on the station. In the hydrogen bottle group; so and so on, the cycle is repeated to realize the function of filling hydrogen.

Description

technical field [0001] This case involves an external hydrogen refueling station, which belongs to the field of hydrogen energy. Background technique [0002] The hydrogen energy industry provides hydrogen energy for fuel cells, and the only place to provide supporting facilities is the hydrogen refueling station, so the hydrogen refueling station is also the connection point between the two major industries of hydrogen energy and fuel cells; [0003] At present, the technical bottleneck restricting the development of the two major industries of hydrogen energy and fuel cells is: the construction of hydrogen refueling stations supporting fuel cells is lagging behind, which is a universally recognized problem worldwide; that is, the hydrogen refueling link of hydrogen refueling stations It is the weakest link; this is a key point, and it is also a breakthrough that we will make in the future. [0004] There are two types of existing hydrogen refueling stations: [0005] One...
