Sealing solutions for electrolysers

Amorim Tech Seal as a response to electrolyzer sealing needs

Amorim Cork Composites has begun to develop cork composite solutions catered to advances in the hydrogen sector, in particular related to electrolysers.

Electrolysers generate hydrogen by splitting water molecules. Choosing the right sealing solution is vitally important for safe storage of hydrogen and is also crucial to ensure that electrolysers perform correctly, guaranteeing the integrity of the system and preventing possible leaks.

The importance of sealing electrolysers

Electrolysers must be effectively and safely sealed in order to optimise their performance and maintain the electrolysis process. Electrolysis systems typically consist of several components - including membranes, electrodes and electrolytes. Sealing materials are applied to the cells where the main reactions take place, preventing electrolytes and gases from escaping. Other external components must also be sealed to ensure a safe environment around the equipment.

Amorim Tech Seal solutions, already well established in the market as effective solutions for sealing different types of gases, are now extending their applications to such hydrogen production equipment. They guarantee effective sealing through good compressibility and a low sealing load.

  • Amorim Tech Seal range meets the sealing requirements of electrolysers

    The Amorim Tech Seal range consists of cork composite solutions that have been specially developed for sealing different types of gases. Cork's cellular structure, which is closed and filled with air, offers advantages for such applications since it endows the system with low thermal conductivity and good acoustic performance, while minimising the material’s lateral expansion, maintaining its properties even when subjected to high levels of pressure over time.

    These solutions are also extremely conformable, since they adjust to the surface and fill in possible imperfections, thereby providing a more effective and secure seal.

    The fact that Amorim Tech Seal solutions incorporate cork - a 100% natural, recyclable and reusable material - guarantees increased performance while contributing to a more sustainable system, compared to using 100% rubber solutions.
