Cell Lab Waterproof Breathable Membrane [Zinc-Air Battery Membrane | Gas Diffusion Layer | Waterproof Air Electrode 100 × 100 mm]

High-performance breathable PTFE membrane for airflow control and electrolyte protection in zinc-air systems

The Cell Lab Waterproof Breathable Membrane is purpose-built for zinc-air and metal-air battery research, offering precise airflow regulation while preventing moisture and electrolyte crossover. Constructed from PTFE and conductive carbon, it provides exceptional hydrophobicity, mechanical strength, and chemical stability. This functional gas-diffusion membrane ensures long-term electrode protection, stable oxygen transfer, and improved power efficiency in both laboratory and pilot-scale ZAB designs.

Key Features

  • Optimised for Zinc-Air Batteries: Enables efficient oxygen diffusion while protecting the air electrode from electrolyte leakage.

  • Hydrophobic & Breathable: PTFE structure allows controlled gas passage while resisting water intrusion and corrosion.

  • Chemically Stable Composite: Carbon-reinforced PTFE membrane maintains conductivity and thermal durability.

  • Uniform Porosity: 20 – 25 % pore ratio ensures balanced ion and gas-exchange characteristics.

  • Easy Integration: Supplied in 100 × 100 mm cut-to-fit sheets for flexible assembly and experimental use.

FAQ

Q1: What is the function of this membrane in a zinc-air battery?
It controls oxygen entry to the cathode while blocking liquid electrolyte from escaping or contaminating the air side.

Q2: Can it be reused after testing?
For consistent results, Cell Lab recommends single-use or limited reuse depending on exposure duration and chemical contact.

Q3: Is the membrane electrically conductive?
Yes. The carbon component enhances surface conductivity for improved electrode interaction.

Q4: How should it be stored?
Store in a dry, dust-free environment below 40 °C to preserve porosity and hydrophobic properties.

Q5: Is it compatible with other metal-air systems?
Yes. It is also suitable for aluminium-air, magnesium-air, and other oxygen-dependent electrochemical devices.
