Filtration Fuel Cells

Fuel cell systems are a key technology for generating energy sustainably, and thus also for climate-friendly mobility with no harmful emissions. Using hydrogen as a fuel in a noiseless electrochemical process leaves only water and atmospheric oxygen as emissions. This process does, however, bring some challenges.

To enable the safe and efficiency-optimized operation of fuel cell stacks, Hengst offers high-performance filtration solutions: the Blue.iox ion exchanger, a specially developed cathode air filter and a new type of separator module for anode gas recirculation. Developed as modular or customized modules, they effectively help expand CO₂-neutral mobility.

In this way, as an experienced specialist in filtration and fluid management, we live up to our corporate vision of “purifying our planet”.

  • Safe and efficiency-optimized operation of the fuel cells

  • Effective protection against premature loss of performance

  • Available as a modular module or customized
