Proton Exchange Membrane Global Market Share, Trend, Segmentation and Forecast to 2021

Global Proton Exchange Membrane Market is segmented, By Product Type, into Nafion PEM, Others. Proton exchange membranes have the ability to transport or exchange protons. These membranes are usually made from either inorganic or organic ionic polymers. Ionic polymers display both – non-directionalionic and directional covalent bonding in the the molecular structure of the polymer chain or network. The covalent bond delivers structural faithfulness, whereas the ionic bond delivers structural functionality for frequent applications.


A proton exchange membrane or polymer electrolyte membrane (PEM) comes across as a semipermeable membrane devised from ionomers and designed for conducting protons while acting as an electronic insulator and reactant barrier, e.g. to hydrogen and oxygen gas. This is their mandatory function when joint into a membrane electrode assembly (MEA) of a proton exchange membrane fuel cell or of a proton conversation membrane electrolyzer(wherein separation of reactants and transport of protons occurs) while blocking a direct electronic pathway through the membrane.


Proton exchange membrane (PEM) fuel cells operate at comparatively low temperatures (<80ºC or <175ºF), offer quick start-up times, and necessitate only hydrogen and oxygen to operate. PEMs can be made from either pure polymer membranes or from compound membranes where the other materials are engrained in a polymer matrix. Recurrent use polyaromatic polymers while others use somewhat fluorinated polymers.

Contingenton their origin, these polymers are also natural ionic polymers or synthetic ionic polymers (such as polyacrylic acid). In terms of their functionality, they may be cationic or anionic. They are also classified as weak and/or robustcationic and/or anionic, contingent on the extent of the dissociation of ionic functionality.  Proton exchange membranes have also been used as moisture, carbon monoxide, and drug sensors, as carriers for enzymes and functional materials, as solid polyelectrolytes and electromechanical actuators, and for creating photovoltage and photocurrent. These applications could lead to new uses of ion exchangemembranes.
