Hydrogen Recirculation Blower (HRB)

  • Enhanced fuel utilization through effective hydrogen recirculation
  • Reduced hydrogen losses via the anode exhaust
  • Reliable recirculation across the entire operating map
  • Improved gas mixing and moisture distribution within the stack
  • Protection against local hydrogen starvation zones (dry-out)

Add to compare

Hydrogen Recirculation Blower (HRB)

  • The hydrogen recirculation blower (HRB) is used to return unreacted hydrogen from the anode exhaust area back into the fuel cell stack to increase fuel utilization.
  • By using the HRB, hydrogen consumption is reduced while overall system efficiency is increased.
  • Additionally, it ensures recirculation across the entire operating range and supports gas mixing and moisture distribution within the stack.
  • The hydrogen recirculation blower from Purem by Eberspächer remains continuously open when idle, making it an ideal choice for combination with a passive ejector unit.

Key fetaures

  • Based on proven Vairex side channel compressors for air supply
  • Highly impermeable to hydrogen (prevents leaks)
  • Corrosion-resistant materials (hydrogen compatible)
  • Vibration- and shock-resistant design

Application areas

  • Hydrogen applications
