Fuel Cells

Due to the wide variety and performance range of fuel cells, they can be used in many different applications, such as mobile applications in mobile phones, laptops, cars or buses, as well as powering apartment buildings or commercial buildings. The fan is a key component in the oxygen supply, thermal management, water management and safe operation of the fuel cell system, which directly affects the efficiency, life and reliability of the fuel cell stack.

 

Ventilation and Coling Fan

  1. Oxygen supply and air-fuel ratio control

 

  • Cathode oxygen supply: The fan pressurizes and delivers air (oxygen concentration 21%) to the cathode of the fuel cell to ensure sufficient oxygen (excess coefficient 1.5-2.0).
    • Data: The energy consumption of the air compressor accounts for 20%-30% of the total power consumption of the fuel cell system. After optimization, the efficiency is increased to >55%.
    • Case: Toyota Mirai air compressor power consumption is reduced by 40%, and the net power of the system is increased by 15%.
  • Dynamic adjustment: The variable frequency fan adjusts the air volume (such as 0-200g/s) according to load demand to avoid excess oxygen (parasitic power consumption) or insufficient oxygen (voltage drop).

 

  1. Water management and humidity control

 

  • Liquid water discharge: The water generated by the reaction needs to be discharged in time to prevent the electrode from being "flooded" (blocking the gas diffusion layer).
    • Solution: The fan drives the air flow to take away the cathode water vapor, and the liquid water is recovered in combination with the condenser (recycling rate >90%).
  • Membrane humidity maintenance: The proton exchange membrane (PEM) requires a humidity of 50%-100%, and the fan adjusts the intake humidity (such as humidification/dehumidification module linkage).

 

  1. Heat dissipation and thermal management

 

  • Stack cooling: The efficiency of the fuel cell is about 50%-60%, and the waste heat needs to be discharged by the heat dissipation system (80-90℃ coolant temperature).
    • Solution: The centrifugal fan drives the radiator airflow (air volume > 500m³/h), and the temperature difference is controlled at ±2℃.
  • High temperature adaptability: Solid oxide fuel cells (SOFC, operating temperature 600-1000℃) require high temperature resistant fans (ceramic bearings + nickel-based alloy impellers).

 

  1. Safety and emission control

 

  • Hydrogen leakage protection: The fan maintains a slight negative pressure in the stack cavity (-50Pa to -100Pa) to prevent hydrogen accumulation (explosion risk when the concentration is > 4%).
    • Technical points: Explosion-proof design (ATEX certification) + hydrogen sensor linkage alarm.
  • Exhaust emissions: Unreacted hydrogen and oxygen need to be diluted and discharged safely (H₂ concentration <1%), and the fan drives the exhaust system.
