Hydrogen has very special properties and requires innovative, tailor made sealing solutions. Seal materials must demonstrate:

  • Low temperature capabilities
  • Ability to withstand explosive decompression
  • Suitability for use in high pressure environments
  • Low permeation to prevent leakage of very small hydrogen molecules

 

Sealing technology plays a crucial role in three main subsystems of fuel cell electric vehicles (FCEVs):

  • Hydrogen circuit
  • Air circuit
  • Thermal management

    •  

Trelleborg Sealing Solutions is developing and testing new materials and solutions for these subsystems to ensure efficient driving and passenger safety.

Heavy Duty FCEVs

Hydrogen fuel cell trucks convert chemical energy into electric energy with high efficiency and can be used in a broad range of applications.

 

Many OEMs are betting on hydrogen-powered fuel cells because they can support:

 

  • Longer ranges
  • Heavier payloads 
  • Longer uptime via faster refueling


The expectation is to have an operational range comparable to many diesel trucks (up to 1000 km) and less of 15 minutes refueling time.

 

When running with green hydrogen*, the only byproduct emitted is water vapor. Therefore, it is a sustainable way to transport goods and will play a major role in the future energy mix. 

 

* Produced by using renewable energy sources.
