Description
Technical Field

The device is divided into a fixed hydrogenation station and a mobile hydrogenation station in a construction form. The hydrogen storage state is divided into a liquid hydrogen station and a high-pressure hydrogen station. The device is divided by a filling mode and can be divided into a single-stage filling hydrogen filling station and a multi-stage filling hydrogen filling station. The hydrogen production mode can be divided into a water electrolysis hydrogen production station, a methanol on-site hydrogen production station, a natural gas on-site hydrogen production station, a gasoline on-site hydrogen production station and the like. The hydrogen source is divided into an external hydrogen supply hydrogenation station and an internal hydrogen production hydrogenation station. The hydrogen production in the station comprises hydrogen production by water electrolysis, hydrogen production by natural gas or methanol reforming and the like. In-station hydrogen production can eliminate the high hydrogen transportation cost, but increases the complexity of the hydrogen station system.
The existing hydrogen stations are mainly divided into two types, namely Off-Site hydrogen production (Off-Site) and On-Site hydrogen production (On-Site). The Off-site hydrogen production (Off-site) can meet the hydrogen demand of a large fuel cell vehicle, the hydrogen is guaranteed, the phenomenon of degassing cannot occur, compressed hydrogen of less than 20MPa is conveyed into the station from a production unit by a hydrogen long-tube trailer, and then the compressed hydrogen is pressurized and unloaded to a high-pressure hydrogen storage bottle group in the station by an in-station compressor and is stored at the pressure of not more than 45 MPa. When the vehicle hydrogenates, hydrogen is output from the hydrogen storage cylinder group and is filled into a vehicle-mounted hydrogen storage cylinder of the fuel cell vehicle through a hydrogenation machine. The need for a compressor to pressurize the material involves a significant risk and is costly.
Accordingly, there is a need for improvements in the art.
