PEM Soft goods: Membrane and Electrode Assemblies (MEAs)

  • For use in all proton exchange membrane applications.
  • Custom sizes up to 20 cm x 20 cm (active area) and in virtually any shape. 
  • Standard size MEAs stocked include 5 cm2 25 cm2 and 50 cm2.
  • For use in all types of fuel cells and electrolyzers, including:
    • hydrogen-air
    • reformate-air
    • hydrogen-oxygen
    • direct methanol fuel cells

 

  • MEMBRANES
    • Standard membranes available:
      • NafionTM1035
      • NafionTM105
      • NafionTM112
      • NafionTM115
      • NafionTM117
    • Other Membranes are available on special request.

 

  • CATALYSTS
    • Standard catalysts available:
      • Pt on Carbon
      • Pt Black
      • PtRU
      • IrRu
    • Other Catalysts are available on special request, or send us your custom catalyst and we will apply it to the membrane for your use.

 

  • Normal range of loadings is from 0.3 mg/cm2 to 12.0 mg/cm2.
  • Supplied with or without gas diffusion layers.
  • MEAs without gas diffusion layers feature two thin film electrodes applied directly to the membrane.
  • MEAs with gas diffusion layers can have the catalyst as either a thin film on the membrane or on the gas diffusion structure.
  • Can be either symmetrical, with identical electrodes on both sides or asymmetrical with different catalysts on each side.
  • Can be furnished with a thin film electrode on one side of the MEA and a gas diffusion structure on the other.
