Bipolar Plate Sealing Solutions – Parker Hannifin

  • Various solutions are suitable for sealing bipolar plates. The simplest and least expensive method is using a fully elastomeric seal.
  • These seals can be produced conventionally in a mold or by using a continuous method for nearly any desired size and shape.
  • As an improved alternative to an elastomeric seal, Parker offers both Gask-O-Seals® and Integral Seals™, which are custom designed plates with over-molded elastomeric seals.
  • Parker’s plate seals simplify assembly and reduce the risk of installation errors, especially in the case of smaller and more complex sealing structures.
  • The utilization of a plate seal not only enhances the handling of the seal but also eliminates the need for set screws in the bipolar plates.
