Nafion™ PFSA Polymer Dispersions

DuPont’s Nafion™ PFSA polymer dispersions are made from chemically stabilized perfluorosulfonic acid (PFSA) / polytetrafluoroethylene (PTFE) copolymer in the acid (H⁺) form, and are available in several polymer content and dispersant compositions. Typical uses include fabrication of thin films and coating formulations for fuel cell membranes, catalyst coating, sensors, and a variety of electrochemical applications.

Fuel Cell Applications:  Nafion™ solution (a diluted, liquid form of the same chemical used for a PEM fuel cell membrane) drastically reduces the amount of platinum needed as a catalyst by exposing a larger fraction of the platinum to the hydrogen gas.  Also, the Nafion™ acts as a binding agent to hold the platinum, membrane, and gas diffusion layer together.
