Product Description

The HPM series proton exchange membrane for water electrolysis is a reinforced perfluorosulfonic acid proton exchange membrane (PEM) widely used in electrolyzers. It has high proton conductivity, high selectivity, and high stability in both acidic and corrosive environments. Membranes are identified by type and identification (batch) number.

1.Before testing, please place the membrane samples in a laboratory environment (23±2℃/73.4±3.6℉, 50±5%RH) for 24h;

2.Test condition is 25±2℃/73.4±3.6℉, 100%RH;

3.It is tested with 10mm rectangular sample, tensile rate: 50mm/min.

Suggested Activation Methods:

On-line activation process:

1. After finishing production process of CCM, please keep the CCM dry, seal it and then place it in the electrolyzer;
2. Cycle pure water at a certain temperature (80℃ /176℉ ) into the anode side of the electrolyzer, and activated for 4 hours with 
low current (1→2A).

Notes:

1.Keep the membranepackage closed/sealed before use;

2.Open the package and handle it in a clean and dust-free areainuse,all surfaces in contact with the membrane must be smooth and flat (experimental gloves must be worn during operation)；

3.Store the membranein its original packaging and stack horizontally to avoid prolonged exposure to light or high temperatures (> 40℃/104℉)afteruse.

Delivery Methods:
