N-115W Perfluorosulfonic Acid Proton Exchange Membrane for PEMWE

Product Type: PEMWE Hydrogen Production Proton Exchange Membrane

commercial grade product

Product Overview

N-115W is a 125 μm membrane with a basis weight of 246 g/m². Part of the W-series designed specifically for hydrogen energy applications, it offers high conductivity, low gas permeability, and enhanced flexibility. This grade is optimized for hydrogen energy systems requiring improved ductility.

This membrane family is positioned for hydrogen-focused equipment requiring higher elongation grades and a dissolved hydrogen concentration reference value. The standard product size is 1 m x 1 m, equal to 1 m²; other dimensions should be confirmed separately before quotation.

Performance Features

High-Flexibility: Provides 125 μm thickness with enhanced elongation ≥200% for better handling and assembly.
Mechanical-Strength: Delivers tensile strength ≥28 MPa and elastic modulus ≥200 MPa for balanced durability.
High-Conductivity: Offers conductivity ≥0.100 S/cm for efficient proton exchange.
Acid-Capacity: Maintains acid capacity at 1.00+/-0.05 meq/g for stable operation.
Standard-Square Footprint: Supplied as 1 m × 1 m (1 m²); other dimensions available upon email request.

How does the 125 μm thickness of the N-115W membrane affect gas crossover and mechanical durability in PEMWE operation?

The 125 μm thickness provides a balanced trade-off between mechanical robustness and gas crossover. With a tensile strength ≥28 MPa, elastic modulus ≥200 MPa, and elongation ≥200%, the membrane offers enhanced flexibility and durability for assembly and operation. However, the dissolved hydrogen concentration reference value is 1000 ppb maximum, indicating that at this thickness, hydrogen crossover is a design consideration for high-pressure or high-current-density PEMWE cells.

What are the water uptake and water content specifications for the N-115W membrane, and how do they influence proton conductivity and dimensional stability?

The N-115W membrane has a water uptake of 50.0 ± 5.0% and a water content of 5.0 ± 3.0%. These parameters ensure sufficient hydration for proton conductivity ≥0.100 S/cm while maintaining dimensional stability. The specific gravity of 1.98 and acid capacity of 1.00 ± 0.05 meq/g further support consistent ion exchange performance under hydrated conditions.

What are the standard sheet dimensions and custom sizing options for the N-115W membrane?

The standard product size is 1 m x 1 m (1 m²). Custom dimensions are available upon email request and must be confirmed separately before quotation. Standard packaging ensures membrane protection during transit, and for custom sizes, dimensions should be included in the inquiry to Atomfair's technical sales team.

Assessment

The N-115W is a 125 μm perfluorosulfonic acid membrane optimized for PEM water electrolysis, offering high proton conductivity (≥0.100 S/cm) and enhanced flexibility (elongation ≥200%) for improved handling in hydrogen production stacks.

Positive

High proton conductivity: Conductivity ≥0.100 S/cm enables efficient proton transport in PEM water electrolysis, reducing ohmic losses in the cell stack.
Enhanced flexibility for assembly: Elongation at break ≥200% improves ductility, reducing the risk of cracking during roll-to-roll processing or stack assembly.

Trade-offs

Limited standard sheet size: The standard size is 1 m x 1 m; custom dimensions require email confirmation and may increase lead time or minimum order quantity.
Water content tolerance: Water content is 5.0 ± 3.0% and water uptake is 50.0 ± 5.0%, requiring careful preconditioning and humidity control for consistent performance.
