ePTFE Reinforced PFSA Membrane for High-Performance PEM Fuel Cells - HPM-18XX

Introducing the ePTFE Reinforced PFSA Membrane, also known as a cation exchange membrane.

This cutting-edge membrane functions as a separator and solid electrolyte in various electrochemical cells, eliminating the need for liquid acids. It provides exceptional proton and cation transport across cell junctions, from the anode to the cathode catalyst layers.

The HPM-18XX series model, comes with a thickness of 6, 9, 12, and 15 microns, is specifically engineered for high-performance PEM fuel cells.

This ultra-thin membrane effectively separates the anode and cathode compartments in fuel cell stacks, typically utilizing H2/Air as the fuel/oxidant. Its thinness enables high current densities, which are crucial for advanced fuel cell applications.

Experience the exceptional performance and durability of our ePTFE Reinforced PFSA Membrane for your PEM fuel cell needs and beyond.

Key features

High-Performance ePTFE Reinforced PFSA Membrane

Enhanced Durability: The mechanical reinforcement provided by the ePTFE structure significantly extends the operational lifetime of the membrane by mitigating swelling-related stresses.
