Technical specifications:

• Thickness: ~250 µm
• Porosity: approximately 60%
• Diameter of nickel fibers: ~ 18 micrometers
• Nickel purity: >99.5% metallic nickel

Application areas:

• Porous Transport Layer (PTL): Acts as the vital interface between the catalyst and flow field, transporting electrons, distributing reactants, and removing gases.
• Current Collector: Provides an excellent conductive pathway for electrons from the external power source to the cathode.
• Catalyst Support: Its high surface area offers numerous reaction sites for the hydrogen evolution reaction (HER) and Oxygen evolution reaction (OER).
