Application of Hydrogen Compressors in Hydrogen Refueling Stations

Hydrogen compressors are essential components of hydrogen refueling stations. Their primary function is to compress low-pressure hydrogen gas to high pressure to meet the fueling demands of hydrogen fuel cell vehicles.  

Working Principle Hydrogen compressors convert mechanical energy into the compression of hydrogen gas. When hydrogen enters the compression chamber, a piston or rotor compresses the gas, reducing its volume and increasing its pressure. Through multiple stages of compression, the hydrogen reaches the required pressure for refueling stations, typically 20-90 MPa. 

What’s the Hydrogen Refueling Stations ?

• Stockage de l'hydrogène : High-pressure hydrogen is stored in storage tanks to meet the continuous fueling needs of vehicles.  
• Hydrogen Fueling: High-pressure hydrogen is dispensed into a vehicle’s hydrogen fuel cell system through a fueling dispenser.
• Ensuring Hydrogen Purity: Hydrogen compressors are often equipped with efficient filtration systems to ensure the purity of the hydrogen dispensed into vehicles.  

How Dose the Hydrogen Compressor Working in a Hydrogen Refueling Station?

1. Low-pressure Hydrogen Inlet: Low-pressure hydrogen enters the compressor from the hydrogen supply source.
2. Multi-stage Compression: The hydrogen undergoes multiple stages of compression within the compressor, gradually increasing its pressure.  
3. Cooling: The heat generated during compression is dissipated through a cooling system. 
   
    
4. Stockage de l'hydrogène : The high-pressure hydrogen is transported to the storage tank for storage.
5. Hydrogen Fueling: Vehicles enter the refueling station and receive high-pressure hydrogen from the fueling dispenser into their hydrogen fuel cell system.

Three Importances of Hydrogen Compressors in Hydrogen Refueling Stations

• Ensuring Operating Efficiency: High-efficiency hydrogen compressors improve the operating efficiency of refueling stations and reduce fueling time.
• Ensuring Hydrogen Quality: High-purity hydrogen extends the lifespan of fuel cells and improves vehicle performance.  
  
   
• Safety Assurance: Hydrogen compressors must have comprehensive safety protection measures to ensure the safe operation of refueling stations.
