Dupont Proton Exchange Membrane Pretreatment

Product Name

^Name: Proton Exchange Membrane Pretreatment

Product Overview

^{Proton Exchange Membrane (PEM) is an ion selective membrane that provides channels for proton migration and transport, separates gas reactants, and blocks electrolytes in batteries. Proton exchange membrane, also known as proton membrane or hydrogen ion exchange membrane, is a polymer material based on proton conduction. It can transfer hydrogen ions from the anode to the cathode inside the battery, forming a circuit with the transfer of electrons from the external circuit, thereby providing current to the outside world. The Nafion membrane and perfluorosulfonic acid proton exchange membrane developed by DuPont in the United States are currently the most representative types of proton exchange membranes. It has excellent proton conductivity, chemical stability, and mechanical strength.}

^{Product Features}

^{High proton conductivity: to ensure that the battery has efficient energy conversion efficiency.}

^{Low gas permeability: effectively separates the reactive gases of the anode and cathode, avoiding direct contact between them.}

^{High chemical stability: able to maintain stability during battery operation without being corroded by electrolyte or reactive gases. High thermal stability: able to maintain stable performance at higher operating temperatures.}

^{High mechanical strength and dimensional stability: to ensure that the battery's performance will not be affected by membrane deformation or damage during long-term use.}

^{Application Fields}

Fuel cell: As the core component of proton exchange membrane fuel cell (PEMFC), it plays a crucial role in the performance of the cell. PEMFC has the advantages of high efficiency, environmental protection, and no noise, and has been applied in fields such as automobiles and ships.

^{Water splitting: As an ion selective channel, it promotes the H+ions in water molecules to move towards the anode and react with the electrode to produce hydrogen gas, achieving a clean and renewable hydrogen production method.}

^{Membrane separation technology: applied in fields such as wastewater treatment and seawater desalination, it separates different ions through proton exchange membranes.}

^{Environmental protection and biomedicine: used in the field of environmental protection to reduce harmful substance emissions; As a drug delivery system in the field of biomedicine, it controls drug release rate and improves stability.}
