PFS
Fuel Cell Gasket(Metal)
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 (Gasket-on-Plate)
- Graphite Bipolar Plate Integrated Gasket
Function
- Fuel gas sealing
- Inter-cell insulation (Prevention of electrical short circuits)
- Inter-cell stress distribution (Ensuring structural stability of the stack)
Performance
- Maintaining airtightness / Sealing integrity
- 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 to prevent stack overheating.
- Prevents electrical short circuits through inter-cell insulation using polymer rubber materials within the stack.
- 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 that satisfies stringent customer MS (Material Specification) requirements, reflecting the harsh operating environments of fuel cell stacks.
Precision control and automated production technology that compensates for the low stiffness and vulnerability to deformation inherent in ultra-thin fuel cell gasket materials.
