Stack sealing - Seal on Bi-Polar Plate

BPP in fuel cells channel the flow of gases and conduct the heat within the system.
Located between adjacent membrane-electrode-assemblies as graphitic or metallic components they are often designed with over-molded, structured seals.
The elastomeric seals prevent leakage of coolant and reactant fluids, and compensate for manufacturing tolerances of the adjacent components.
NFC has developed seal materials that meet all requirements of the fuel cell environment and lifetime operation.
For Bipolar Plates we offer a fuel-cell specific silicone material and for highest durability requirements a specific polyolefin elastomer.
