Filtration Solutions for Fuel Cells

Products for coolant and air filtration in the area of system integration.


Hengst (Münster, Germany) announced a modular set of various filtration solutions for fuel cells. The specialist in filtration and fluid management presents products for coolant and air filtration, and in the area of system integration, a water separator for anode recirculation.

Blue.iox ion exchanger:

  • Reduces the initial ion concentration in the coolant circuit
  • Offers high level of protection with minimum maintenance
  • Design of the filter cartridge with axial filter flow and the special mixed bed resin system for cation and anion exchange ensure high filtration efficiency over the entire service interval
  • Reduced ion concentration in the coolant circuit
  • Screw cap allows the filter cartridge to be replaced cleanly without special tools
  • Integrated shut-off valves prevent coolant from escaping

Cathode air filter system:

  • Protects the drive even under harsh operating conditions
  • Protects the fuel cell components from particles as well as harmful gases
  • Particle filtration can be applied directly with gas filtration in a combination medium
  • Pleated particulate filter medium used as a separate filter stage upstream of the gas filtration
  • Application areas of the filter system include trucks and buses

To prevent liquid water deposits and ensure the continuous effective operation of the fuel cell, proper water management is crucial. The solution from Hengst: a new type of separator module for anode gas recirculation. It combines the function of droplet water separation and gas drainage with an innovative valve configuration of the purge and drain valve.
