Selective Anion Transport: It can selectively transport anions (such as hydroxide ions OH⁻), thereby achieving efficient electrochemical processes.

As the core component of the membrane electrode in a water electrolysis cell, the proton exchange membrane not only conducts protons and separates hydrogen from oxygen but also provides support for the catalyst.

The PEM (Proton Exchange Membrane) membrane electrode is the core component of the Proton Exchange Membrane Fuel Cell (PEMFC), providing microchannels for the transfer of multiphase substances and a site for electrochemical reactions.

A porous material made from carbon fibers, carbon paper features high electrical conductivity, lightweight, and chemical resistance.
