This product, a DuPont Nafion™ 212 proton exchange membrane, is developed for experimental and research applications in fuel cell technology. As a perfluorosulfonic acid (PFSA) membrane, it offers reliable proton conductivity and chemical stability, making it suitable for evaluating membrane-electrode assembly performance and catalyst layer interactions. Available in various dimensions—from 10 cm × 10 cm tablets to 61 cm × 1 m rolls—it accommodates both small-scale laboratory tests and larger prototyping setups. The Nafion 212 grade provides a standard thickness and ion-exchange capacity commonly referenced in fuel cell research, supporting consistent electrochemical characterization. Typical use cases include membrane conductivity studies, crossover measurements, and durability assessments under controlled operating conditions. This membrane serves as a foundational component for advancing polymer electrolyte fuel cell (PEMFC) studies.
