N-212 Perfluorosulfonic Acid Proton Exchange Membrane for Hydrogen Fuel Cell

Product Type: Hydrogen Fuel Cell Proton Exchange Membrane

commercial grade product

Product Overview

N-212 is the thickest membrane in the series at 50 μm, with a basis weight of 99.0 g/m². The ePTFE microporous reinforcement delivers superior mechanical strength and dimensional stability. This grade is recommended for applications requiring enhanced durability and reduced gas crossover.

The membrane is designed for hydrogen fuel cell applications that require a reinforced proton exchange membrane with controlled thickness, basis weight and electrochemical performance. The standard product size is 1 m x 1 m, equal to 1 m²; other dimensions should be confirmed separately before quotation.

Performance Features

How does the 50 μm thickness of the N-212 membrane affect gas crossover and durability compared to thinner PEMs?

The N-212 membrane is the thickest in its series at 50 μm with a basis weight of 99.0 g/m², which enhances mechanical robustness and dimensional stability while reducing gas crossover. This thickness, combined with ePTFE microporous reinforcement, delivers superior durability for demanding fuel cell stacks, though it may increase ohmic resistance slightly compared to thinner membranes.

What are the tensile and modulus requirements for integrating the N-212 membrane into a high-pressure fuel cell stack?

The N-212 membrane provides isotropic tensile strength of ≥28 MPa in both MD and TD, with an elastic modulus of ≥400 MPa in both directions, ensuring uniform load resistance under mechanical stress. This specification supports reliable integration into stacks requiring high mechanical stability, as the ePTFE reinforcement maintains dimensional integrity during compression and thermal cycling.

What handling and storage conditions are required for the N-212 membrane to maintain its water content and conductivity?

The N-212 membrane has a water content of 5.0 ± 3.0% and water uptake of 50.0 ± 5.0%, requiring controlled humidity storage to prevent dehydration or over-hydration that could affect proton conductivity (≥0.100 S/cm). Standard packaging ensures protection during transit, but for long-term storage, a sealed, low-humidity environment is recommended to preserve electrochemical performance.

Assessment

The N-212 membrane (50 μm) offers mechanical robustness via ePTFE reinforcement and isotropic strength, but requires careful humidity control due to tight water content tolerance and significant water uptake.

Positive

Thickest reinforced membrane: At 50 μm with ePTFE reinforcement, the N-212 delivers superior mechanical strength and dimensional stability while reducing gas crossover for demanding fuel cell stacks.
Isotropic mechanical properties: MD/TD tensile strength ≥28 MPa and modulus ≥400 MPa ensure uniform load resistance across the membrane plane, enhancing durability under stack compression.

Trade-offs

Tight water content tolerance: Water content is specified at 5.0 ± 3.0%, indicating sensitivity to ambient humidity; storage and operation require controlled relative humidity to maintain performance.
High water uptake swelling: With water uptake of 50.0 ± 5.0%, the membrane undergoes significant dimensional change upon hydration, which must be accounted for in stack assembly and clamping design.
