Advanced seals for optimal performance of your hydrogen systems
In the world of green hydrogen, the integrity and safety of hydrogen systems depend on advanced sealing technologies. Whether it’s fuel cells, internal combustion engine, domestic heating systems, reliable seals play a vital role in preventing leaks and ensuring optimal performance of your systems.
Fuel cell
A fuel cell is a system that converts chemical energy into electricity through a chemical reaction between a fuel (often hydrogen) and an oxidizing agent (often oxygen). Fuel cells offer a sustainable energy solution with the potential to power everything from vehicles to entire energy grids with minimal environmental impact.
Requirements
- Withstand pressures from 1 to 4 bars
- Deal with temperatures 20°C to 100°C (LT-PEM) and up to 220°C (HT-PEM)
- High purity and cleanliness (no leachable and extractables that would poison the catalyst)
- Chemical resistance against hydrogen, sulfuric acid (LT-PEM), phosphoric acid (HT-PEM), hot air and water
- Low hydrogen permeation rate
