Detalhes

This product is developed for use as an electrolyte membrane in electrochemical devices such as fuel cells, vanadium redox flow batteries, electrolysis cells, electrodialysis systems, and electrochemical sensors. The Nafion 115 membrane features a thickness of 127 μm and an areal density of 250 g/m², offering a proton conductivity of 0.083 S/cm and an ion exchange capacity of 0.89 meq/g. These properties contribute to its excellent thermal stability, high-temperature resistance, and good electrochemical oxidation resistance. A recommended pre-treatment procedure involves sequential immersion in hydrogen peroxide and dilute sulfuric acid at 80°C, though the membrane may also be used after simple electrolyte soaking depending on established user protocols. This product is suitable for researchers requiring a consistent and durable proton exchange membrane for catalyst-coated or direct use configurations.

Pre-Treatment Method (Recommended):

The N115 membrane can undergo pre-treatment before use. The specific method is as follows:

First, treat it with 5% hydrogen peroxide at 80°C for 1 hour, then immerse it in deionized water for half an hour. Next, boil it in 5% dilute sulfuric acid (by mass) at 80°C for 1 hour. Finally, soak it in deionized water for half an hour.

Alternatively, according to the user's established practice, it can be used after soaking in an electrolyte solution only.

This product is suitable for electrolyte membranes in fuel cells, vanadium batteries, electrolysis cells, electrodialysis, and electrochemical sensors. It has excellent thermal stability, high temperature resistance, good resistance to electrochemical oxidation, and high stability.
