PFSA D50-U Proton Exchange Membrane
PFSA D50-U Proton Exchange Membrane (PEM) is used to separate the anode and cathode compartment of PEM fuel cell stacks that usually consume H2/Air as the fuel/oxidant and requires high current density operations with long lifetime (which necessitates the use of a relatively thin membrane). It is quite a common practice in the fuel cell industry to use thin (50 microns or less) PFSA membranes in order to achieve high current densities that are relevant to the commercial applications. PFSA D50-U Proton Exchange Membrane (PEM) has thickness of 50 microns (+/- 2 microns for the variations in the thickness). This is an unreinforced (also known as self-supporting) PFSA membrane and it is manufactured via solution cast process. While it is not a common practice, this membrane product can also be used in PEM water electrolyzer, vanadium redox flow batteries, direct methanol fuel cells (DMFCs), direct formic acid fuel cells (DFAFC), microbial fuel cells (MFC) and other similar applications and it is always advised that the end-user to take into consideration of the thickness of the PFSA membrane for their particular application and how it may effect the performance positively or negatively.
D50-U expands the possibility of finding an excellent fit for your requirements, without diminishing the worth of Nafion 212.
PFSA D50-U Proton Exchange Membrane is based on the chemically stabilized perfluorosulfonic acid material and it is shipped in the acid (H+) form (which is also known as protonic form). Chemical stabilization is also known as end-group stabilization where the carbon atoms that end of the PFSA polymer chains are fully fluorinated. Chemically stabilized PFSA membranes will exhibit substantially lower fluoride ion release compared to the PFSA membranes manufactured from unstabilized PFSA resin. Functional groups (also known as sulfonic acid sites) for this PFSA membrane are based on the long side chain for its chemical structure.
Proton exchange membranes are also known as cation exchange membranes in the market. This PFSA membrane performs as a separator and solid electrolyte (without the need of a liquid acid) in a variety of electrochemical cells that require the membrane to selectively transport protons or other various cations across the cell junction (or between anode and cathode catalyst layers). The polymer is chemically resistant and durable.
