Description Vendor

The BNHP-26 Hydrogen Recirculation Blower is a centrifugal blowers product from Barber-Nichols for hydrogen and fuel-cell system applications. Its specified configuration includes Volumetric flow rate 16.1 L/s; pressure rise 35 kPa; max rotational speed 42,000 rpm; maximum allowable working pressure 400 kPa; electrical input 200–400 V DC. Its principal deployment contexts include vehicle fuel-cell anode hydrogen recirculation and automotive fuel-cell balance-of-plant systems. The technical design also includes integrated side controller for vehicle-specific packaging, volumetric flow rate 16.1 l/s, pressure rise 35 kpa, speed up to 42,000 rpm. Its documented capability set includes recirculates hydrogen at up to the stated 16.1 L/s volumetric flow; develops a 35 kPa pressure rise; operates at speeds up to 42,000 rpm. For system designers evaluating centrifugal blowers, these details define the model's operating values, physical or control characteristics, and the functions available for integration into the relevant hydrogen process or electrochemical system. The product can also be applied in packaged fuel-cell systems with space-constrained integration, with selection based on the stated specifications and the surrounding system requirements.

Use Cases

  • Vehicle fuel-cell anode hydrogen recirculation
  • Automotive fuel-cell balance-of-plant systems
  • Packaged fuel-cell systems with space-constrained integration
  • Hydrogen circulation requiring integrated motor/controller architecture

Capabilities

  • Recirculates hydrogen at up to the stated 16.1 L/s volumetric flow
  • Develops a 35 kPa pressure rise
  • Operates at speeds up to 42,000 rpm
  • Handles working pressure up to 400 kPa
  • Accepts 200–400 V DC electrical input
  • Provides electrical isolation between controller voltage domains
Barber-Nichols, Inc. Barber-Nichols, Inc. designs and manufactures specialized turbomachinery for demanding fluid and gas applications. Its verified hydrogen products in this batch include a liquid-hydrogen centrifugal pump and hydrogen recirculation blowers for fuel-cell systems.
