Fuel Cell Gasket(Graphite)

Integrated into the hydrogen fuel cell stack, it functions to provide a secure seal for internal gases (hydrogen and oxygen) and liquids (coolant) to prevent any leakage.

Type

    • Metal Bipolar Plate Integrated Gasket

    • Graphite Bipolar Plate Integrated Gasket


    Function
    • Sealing of reactant gases.
    • Inter-cell insulation (Prevention of electrical short circuits).
    • Inter-cell stress distribution (Ensuring structural stability of the stack).
    Performance
    • Maintenance of airtightness.
    • Electrical insulation.
    • Mechanical support and maintenance of compression.
    Size
    • Anode  :  118mm X 413mm ( 0.08t )
    • Cathode  :  118mm X 413mm ( 0.1t )
    Weight
    • Anode  : Approx. 0.029g
    • Cathode  :  Approx. 0.036g
    Features
    • Functions to seal reactant gases (hydrogen and oxygen) and cell coolant used to prevent stack overheating.
    • The polymer rubber material provides inter-cell insulation within the stack to prevent electrical short circuits.
    • Uniformly distributes stress between cells to maintain high stack clamping pressure.
    • High dimensional precision is required for fuel cell gaskets (Precision molding and forming technology).
    PyungHwa Advantages
    • Rubber material technology satisfying stringent customer MS (Material Specification) requirements that reflect the harsh operating environments of fuel cell stacks.
    • Precision control and automated production technology to compensate for the low stiffness and deformation vulnerability inherent in ultra-thin fuel cell gaskets.
