End Plates for Fuel Cell Stacks

  • End plates are critical components that clamp and secure fuel cell stacks, ensuring uniform force distribution and leak-free operation.
  • Insufficient contact pressure can lead to high resistance, performance losses, or component failure.
  • They also serve as the anode and cathode side terminations, enabling connections for gas, electrolyte, and cooling systems.
  • The geometry, materials, and connection methods of end plates significantly influence fuel cell stack performance.
  • Traditionally made of metals, which have limitations like corrosion, high cost, and thermal inefficiency.
  • Ensinger focuses on the processing of thermoplastics which, unlike thermosetting plastics, are recyclable.
  • Ensinger manufactures end plates from glass fiber reinforced PPS (PPS GF40) under the name TECATRON GF40, which is available from stock in thicknesses of up to 60 mm.

Key features

  • Made from glass fiber-reinforced PPS (TECATRON GF40) for enhanced durability.
  • Excellent chemical resistance, low water absorption, and minimal ion leaching.
  • High mechanical strength and stiffness to maintain required contact pressure.
  • Superior dimensional stability and creep resistance for minimal deformation under load.
  • Meets UL94 V-0 flame resistance standards.
  • Optimized through a specialized extrusion process for low-stress machining.

Applications

  • Automotive fuel cell systems.
  • Aviation and aerospace fuel cells.
  • Stationary and portable hydrogen energy systems.
  • Prototyping and scalable production for injection molding.
