Nafion™ NR211 Membrane (N211)

Product overview

NR211 is a distinct solution-cast Nafion grade. Specify NR211 and the required outer dimensions when matching a membrane to an MEA or laboratory cell. Consider the handling, sealing and assembly requirements of the selected grade rather than treating all Nafion sheets as interchangeable.

Selection questions

Is the active area the same as the cut size?

Provide both where relevant. The Nafion™ NR211 Membrane (N211) requirement should allow for the cell geometry and sealing margin, not only the electrochemically active region.

How do I specify a replacement material?

Send the exact grade or current product reference, dimensions and the relevant technical data. Confirm the proposed specification before using it as a replacement.
