Freudenberg Filtration Technologies products

Fuel cells react sensitively to salts, nitrous oxides or compounds with sulfur or ammonia, which can enter the process via the intake air. Effective filtration is therefore essential in order to protect the sensitive components and ensure greater safety. Our filter media are specially developed for the unique requirements of fuel cells. micronAir filters effectively protect the catalyst material and the membranes used in the stack and system components from contaminant gases and particles.

Efficient fuel cell drives depend on reliable membrane humidification. This ensures a flawless reaction and prevents early degradation due to the electrolyte drying out. In short: Fuel cells only achieve sustained high performance with a high-quality humidifier. We offer you long-lasting humidifiers that are adapted to the requirements of your system. The outstanding water transfer rate at a low pressure drop guarantees stable humidification. The hollow fiber technology enables various housing geometries that have been tested in real operation and optimized. These can be easily adapted to your system requirements without major investments. From evaluation with standard modules to the manufacture of prototypes all the way to individual series production – we are happy to assist you with new developments from the very start.
