NC700 Ultrafine Proton Exchange Membrane

Overview

NC700 is an ultra-thin proton-conducting membrane around 15 µm thick, intended for research where the lowest possible ohmic drop is required. Such thin membranes are ideal for high-current, well-humidified systems and short-duration test work.

Mechanism
The membrane transports protons through hydrated ionic clusters but, due to its low thickness, must be supported by accurate compression and leak-free sealing.

Key features

• Extremely low thickness (~15 µm)
• Very low area-specific resistance
• Enables high current density at moderate temperatures
• Best suited to precision-built PEM or MEA cells
• Requires careful handling to avoid creasing or tearing
  
  

Applications

• Advanced PEM fuel cell studies
• Electrolysis stack concept testing
• Educational demonstrations of resistance vs thickness
• Comparative membrane screening
  
  

Why ScienceGears
We can recommend gasket thickness, clamping hardware and complementary instruments so researchers in Australia & New Zealand can run reproducible tests.
