Replacment - Repair PEM for Parker / Bolston, Packard and Scott Hydrogen Generators - a possibly some others.  115 Nafion coated Platinum black on one soide and  Iridium Ruthenium Oxide on the other.  If your generator does not develop pressure and / or has water on the Hydrogen side - then the membrane is likely got a hole in it and THEY CaNNOT BE REPAIRED - but only replaced.  This membrane is higher performance than what was in there.  Custom made


You should check to see how many membranes are in the unit before ordering - NOTE:  Bare Nafion does nothing - you must have  a Catalyst Coated Membrane (CCM) installed in the proper Anade - Cathode coating dirextion.


Designed for high efficiency production of Hydrogen and Oxygen.. It is a 3-layer, or Catalyst Coated Membrane (CCM), designed to provide some of the highest efficiencies and purest hydrogen via electrolysis.
