Silicone flat gasket for PEM fuel cells & electrolyzers

Our silicone flat gaskets offer exceptional dimensional stability, ensuring precise alignment during stacking. The advanced manufacturing process results in an ultra-smooth surface finish, which guarantees excellent gas and water tightness within the cell—even under minimal contact pressure. This eliminates the need for additional sealing components. The material is available in customizable thicknesses, typically ranging from 200 to 700 µm. During production, we maintain a tight thickness tolerance of just a few micrometers, supporting consistent performance across applications.
