Hydrogen Fuel Cell membrane 3015
MEMBRANES FOR FUEL CELLS
N-3010 N-3015 and N-3025
Our PFSA membranes perform as a solid polymer electrolyte in fuel
cells and other applications in electrochemistry and separation
technology for a variety of electrochemical process and devices
including chlor-alkali cells.The membranes are located between the
cathode and anode and transports protons formed near the catalyst
at the hydrogen electrode to the oxygen electrode thereby allowing
the current to be drawn from the cell.
PFSA N-3010 N-3015 and N-3025 membranes are reinforced membranes
based on chemically stable perfluorosulfonic acid (PFSA) copolymer.
Incorporation of the porous reinforcement such as ePTFE improves
the mechanical property of the composite membrane and allows the
membrane to restrict its swelling. The membranes show significant
improvements in features such as better resistance to chemical
attack and longer operating durability in fuel cells.
The membrane is typically positioned on a coversheet. This
composite membrane is wound on a plastic core, with the coversheet
on the core-side, as shown in Figure 1. A 15.24cm ID plastic roll
core is standard.
The membrane combined with the coversheet eliminates rapid changes
in the membrane’s water content, and stabilizes the dimensions of
the membrane when removed from the roll.
Order and Packaging Information
Our PFSA membranes are available in two thickness values: N-3010
N-3015 and N-3025.
The standard product specifications for membrane pieces include:
l Width: 0.30 m (min.) to 1.00 m (max.)
l Length: 0.30 m (min.) to 1.00 m (max.)
The membrane for cut pieces will depend on the size and quantity of
the customer’s order requirements. All the flatted membranes are
shipped on a roll. Flat membranes are directly wound into a small
roll. The membranes are protected with a polyethylene wrap and
inner packaging, then placed in shipping hard cartons.
The standard product specifications for membrane rolls include:
l Width: 610mm and 800mm standard widths; other widths are
available from 200mm to 400mm in 100mm increments on special order.
l Length: 100-meter standard roll length, other non-standard
lengths are feasible to meet orders of the custome.
There is a 50 m2 minimum order requirement for non standard roll
widths and lengths. Membrane pieces or rolls can be cut to non
standard sizes, and special packaging provided at additional cost.
Please contact our sales staff for details and availability.
Membrane dimensions are based on dry product conditioned at 23 °C
and 50% relative humidity(RH) before cutting. The moisture content
of the membranes will have an influence on their size changes
including in the length, width, and thickness directions. Once the
coversheet is removed, the membrane will adjust to the environment
conditions. The membrane typically adheres to the coversheet, to
the extent that it reduces the dimensions.

The membrane shall be easily peeled off from the coversheet during
this step. The coversheet is 125 micron polyester film.
The membrane shall be wound on the inside of the roll such that it
is protected from contamination and physical damage during
A self-adhesive product label is placed on the inside of the roll
core and on the outside over-wrap of each roll. The label contain
the following information: Membrane Type, Supplier Lot Number,
Recommended Storage Conditions
Prior to opening the original shipping box, the membrane does not
require environmentally controlled storage. Membrane should be kept
sealed in its original packaging until needed. After opening the
package, store the material in a temperature and humidity
controlled environment(temperature 25.0±5.0°C and humidity
45±5.0%RH). Acclimatize the membrane to the manufacturing
environment for at least 48 hours prior to use.
Once opened and exposed to the environment, the membrane will
equilibrate to the ambient relative humidity, and change in
Preferred disposal options are recycling and landfill. Incinerate
only if incinerator is capable of scrubbing out hydrogen fluoride
and other acidic combustion products. Treatment, storage,
transportation, and disposal must be in accordance with applicable
national laws and regulations.
The process of recycling waste Fluoropolymer Resins is extremely
complicated as there are many parts to be recycled and many
hazardous materials to remove. Therefore, we recommend that it is
more appropriate for customers to hand over the waste membrane to
us for recycling.
