Form
Nafion™ N-424 is shipped in the "DRY" H+ form.  "DRY" H+ membranes require simple pre-treatment in alkaline water.  Refer to Nafion™ Technical Bulletin No. 93-01 for "DRY" H+ membrane pre-treatment.
Please Note:
The side marked CATH must be installed facing the cathode, otherwise, the membranes will be irreversibly damaged in use. If your membrane is not marked simply feel/look at both sides of the membrane, the smoother/glossier side will be the cathode side.
