Proton Exchange Membrane for Batteries Lab Applications

Introduce  

The thin proton exchange membrane has excellent properties, including low resistivity, high proton conductivity, and minimal hydrogen permeation current density, ensuring a long service life. This type of membrane can be used in proton exchange membrane (PEM) fuel cells, direct methanol fuel cells (DMFC) and water electrolyzers. In electrochemical cells, its key roles include separating the negative and positive compartments while acting as a solid electrolyte. In addition, it selectively transports cations to the cell junction. It is worth noting that there are several non-reinforced Nafion membranes available such as N117, N115, NR212 and NR211, each with different thickness dimensions. Selection of an appropriate membrane thickness depends on specific factors including desired transmembrane pressure drop, atmosphere relative to oxygen generation, type of membrane support, and expected operational lifetime. Proper consideration of these factors will lead to the best choice for a successful application.

Detail & Parts

Models above N211, N212, and NC700 have two layers of protective film.

Pretreatment can be carried out before use. The specific method is: first treat 5% hydrogen peroxide at 80°C for 1 hour, then soak in deionized water for half an hour, and then cook with 5% dilute sulfuric acid (mass ratio) at 80°C for 1 hour , and finally soak in deionized water for half an hour.

Technical specifications

The width is 30.5cm, and can be cut into 10*10cm, 20*10cm, 20*20cm, 40*40cm, 30.5* and other sizes for sale according to customer requirements.

The products we show are available in different sizes and custom sizes are available on request.
