Hydrogen Fuel Cell Proton Membrane PEM
perfluorinated ion membrane n-30x PTFE reinforced series is a composite perfluorosulfonic acid h-type proton exchange membrane produced by corona company by steel strip fluidization method combined with ePTFE microporous reinforced material.
Perfluoroionic membrane n-30x PTFE reinforced series is a composite perfluorosulfonic acid h-type proton exchange membrane produced by steel strip fluidization method combined with PTFE microporous reinforced material. N - 30 x PTFE reinforced proton exchange membrane with cationic one way through the properties of the used PTFE microporous membrane as a skeleton with high-performance perfluorinated sulfonic acid ion exchange resin, adjust the most suitable molecular weight and ion exchange capacity, with a thickness of thin, low strength, high electrical conductivity, swelling, size stability, good durability, etc. N-30x PTFE enhanced proton exchange membrane is particularly suitable for use in fuel cells.

1. Measurements taken with membrane conditioned to 23°C, 50% RH.
2.Conductivity measurements a 23 °C, 100% RH.
3.A base titration procedure measures the equivalents of sulfonic acid in the polymer, and uses the measurement to calculate the acid capacity or equivalent weight of the membrane.
4.Water content of membrane conditioned to 23 °C and 50% RH (dry weight basis).
5.Water uptake from dry membrane to conditioned in water at 100 °C for 1 hour (dry weight basis)
Application:
Fuel cell
Packing:
coil
Standard volume: 0.2m*100m;
Special specification: >0.2m width, arbitrary length. (for special specifications, the order quantity should be over 100 square meters and the width should not be greater than 0.6m)
Film dimensions are based on dry film products prior to cutting, at 23°C and 50% relative humidity. The humidity and temperature of the air will affect its size. The products that need to be pretreated by our company are guaranteed to be of positive tolerance, and the products after preprocessing are all sheet materials.
Film packaging, the use of the volume, less than the volume of no core, a larger number of containing the core. The dry film all USES the hard protective film to make the bottom protection, the outer packing USES the plastic bucket or the hard carton packing. Please contact the sales staff for special size and packing.
Recovery and treatment:
As the product will volatilize toxic and harmful substances during incineration, it can be disposed by landfill. Only if the incinerator is capable of removing hydrogen fluoride and other acidic combustion products. The disposal of this product must comply with the relevant local laws and regulations.
Our company provides paid recycling service for perfluorinated ion membrane waste. For details, please contact our sales staff.
