1. Introduction

Fumasep FAB-PK-130 is a PK reinforced Anion Exchange Membrane (AEM) with high proton blocking capability, high selectivity, very high mechanical stability, and high stability in acidic and caustic environment. The polymer backbone for this AEM is based on a hydrocarbon polymer material.

Fumasep FAB-PK-130 is designed for the processing of concentrating acidic solutions, electrodialysis and electrodialysis with bipolar membranes.

2. Delivery

The membrane is the brown foil, delivered in between paper layer. Carefully separate the membrane from the paper layers. The membrane is delivered in dry form.

The standard size of this membrane is 10*10cm & 20*30cm. Customized dimensions can be made upon request.

3. Precautions

FuMA-Tech membranes are highly sensitive to differences in humidity and moisture content. Therefore the membranes can vary +/- 0.5cm from the original cut sizes. Also due to this sensitivity the manufacturer expects wrinkles to form, however soaking the membranes in deionized water will return the membranes to the full size planar state according to the manufacturer.

- Applications: Process for concentrating acidic solutions, electrodialysis and electrodialysis with bipolar membranes.
- Anion Exchange Membrane
- Stability Range (pH) at 25°C: 0 - 14
- Thickness: 130 micrometers (μm)

fumasep FAB-PK-130 (dry form) Technical Data Sheet.pdf

Keep membrane package closed / sealed when unused. Store, handle and process the membrane in a clean and dust-free area. Use only new and sharp knives or blades, when cutting the membrane. Always wear protective gloves when handling the membrane. Handle with care, be sure not to puncture, crease or scratch the membrane, otherwise leaks will occur. All surfaces in contact with the membrane during handling, inspection, storage and mounting must be smooth and free of sharp projections.

Dry form: The membrane can be stored dry for an unlimited amount of time. However, the membrane has to be conditioned (washed and rinsed) prior to use.

Wet form: Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 - 1.5 wt% NaCl solution or comparable neutral pH electrolytes.

For storage over a longer time period a sealed container is recommended using afore said electrolyte with ca. 100 ppm biocide (NaN₃) to avoid biological fouling.

The membrane is delivered in the bromide form and dry. Depending on application and cell design, assembling is possible in dry form (without pretreatment) or wet form. For optimum performance it is recommended to rinse the membrane in NaCl solution (e.g. 0.5 M NaCl solution at 25°C for 24 hrs) to remove any additive from the membrane. Place the membrane sample between stabilizing meshes / spacers in order to avoid curling. Do not let the membrane dry out since micro-cracks may likely occur during shrinkage.

For standard alkaline fuel cell / electrolysis applications

The membrane should be converted into OH-form by treating it with 0.5 – 1.0 M NaOH or KOH solution: Put the membrane sample in an aqueous solution of 0.5 – 1.0 M NaOH or KOH for at least 24 h at 20°C – 30°C. After rinsing with demineralised water (pH ~ 7) the membrane is ready to use. Use closed container to avoid CO₂ contamination (carbonate formation that may affect conductivity). The membrane in OH-form must be stored under wet / humidified and CO₂-free conditions, avoid drying out of the membrane in OH-form. Long-term storage in dry conditions should be preferably done in carbonate, Cl- or Br-form.

For other electrochemical (electrodialysis, desalination, electro-electrodialysis, reverse electrodialysis, acid recovery, salt splitting, etc.) and non-electrochemical applications

the membrane should be converted into the anionic form that is relevant for the intended application. For example, if the application is requiring the Cl^- anions to be transferred through the membrane, then this anion exchange membrane needs to be converted into the Cl^- form. In order to convert this membrane into Cl^- form, it needs to be submerged into a 1-2 M salt solution of NaCl or KCl (dissolved in deionized water) for a period of 24-72 hours and then rinsed with deionized water to remove the excess salt from the membrane surface. Or if the intended application is requiring to transfer sulfate anions, then this anion exchange membrane needs to be converted into the sulfate form prior to its assembly into the cell. A neutral salt solution of Na₂SO₄ or K₂SO₄ would usually be sufficient to achieve the full conversion of membrane into the sulfate form after fully submerging the membrane into the salt solution for 24-72 hours at room temperature.
