The Future Is Hydrogen

Our design teams worldwide are looking forward to bringing their know-how and experience to develop the best sealing solution for you. If you are a developer of fuel cells or electrolyzers, you might be looking for stack sealing solutions that can compensate for manufacturing tolerances, distributes all linear loads evenly across the cell area and facilitates automated mass production. Let us work with you from an early in the development process to help ensure best interplay of all stack components for an economic solution. However, also for advanced design stages, we offer solution for seamless integration and maximum sealing performance and durability.

With our strong background in the automotive and the chemical industry, we offer custom designs for a wide range of static and dynamic seals for valves, compressors, pumps, and engines in the hydrogen and power-to-x applications.

As the basis for application-specific elastomer development, we can draw on more than 1,500 material formulations. Our expertise in materials and processes makes us a valued partner to help our customers at critical points in the development and meet extended durability targets.

For hydrogen applications, we have developed a series of low-permeation elastomers to ensure the highest efficiency across all use-cases. In many high-pressure applications, rapid gas decompression can jeopardize long-term durability of elastomeric seals. Our compounds are thus tested and optimized to withstand these harsh conditions for maximum seal lifetime.

Specifically for electrochemical energy converters, chemical resistance is a challenge we can overcome with our high-performance elastomers that resist high temperatures, pressures, compressive deformation and even the harsh electrolysis environment. Besides their chemical resistance, these compounds meet high cleanliness requirements and are designed to prevent leaching of any catalyst poisons that could hamper the long-term performance of electrochemical cells.

At Freudenberg Sealing Technologies, material testing and evaluating conditions relevant to various applications is part of our DNA as operator of the largest Simmering testing facility world-wide. With extensive in-house knowledge, we specialize in assessing application-relevant conditions across all stages of the hydrogen value chain. Our expertise covers everything from production and processing to distribution and storage all the way to utilization, ensuring that materials and components meet stringent standards for performance and safety.

Our company excels in testing static seals to determine leakage under relevant operational conditions, ensuring reliability and safety. We specialize in accelerated aging of materials in application-relevant media, spanning a wide temperature and pressure range. Additionally, we determine empirical parameters for our materials in-house, providing accurate data to feed simulation models. All these services are delivered seamlessly, offering comprehensive solutions from a single source.

On top of that, we are continuously expanding our testing capabilities to stay at the forefront of innovation, enabling us to provide comprehensive solutions tailored to the evolving needs of the hydrogen industry. This commitment to excellence ensures reliable and efficient performance in all hydrogen applications.
