Membranes, in general, are selective barriers available in different shapes and sizes for separating gases or liquids based on different factors.
An ion-exchange membrane is a semi-permeable membrane that transports certain dissolved ions, while blocking other ions or neutral molecules. They are therefore electrically conductive moving ions from one solution to another with little passage of water.
Examples of ion-exchange membranes include the proton-exchange membranes (PEM), that transport cations, and the anion exchange membranes (AEM) used in certain alkaline fuel cells to transport anions.
Anion exchange membranes (AEM) are membranes which have positively charged functional groups. These membranes allow the transport of anions, while rejecting cations.
In Nordische, AEM membranes are develoved from a polymer derivative both by casting and electrospinning for different applications like fuel cells, hydrogen production, metal extraction, gas separation, desalination etc.
These Ion Exchange membranes are available in all sizes and shapes.
Nordische is offering a proton Exchange Membrane, is a vital component in fuel cells and other electrochemical devices, enabling efficient conversion of chemical energy into electrical energy. An overview of PEM, its applications, advantages, and its significance in various industries is given below.
A proton exchange membrane, also known as a polymer electrolyte membrane, is a thin, selective barrier that allows the passage of protons while preventing the mixing of fuel and oxidant gases in a fuel cell. The membrane is typically made of a polymer material which is cellulose derivative and impregnated with a suitable electrolyte, which facilitates the movement of protons (H+ ions) across the membrane.

Importance in Various Industries:
Proton exchange membrane technology has significant implications across several industries:
Membranes, in general, are selective barriers available in different shapes and sizes for separating gases or liquids based on different factors.
A molecular sieve is a material with pores (very small holes) of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can. They are crystalline metal aluminosilicates having a three dimensional interconnecting network of silica and alumina tetrahedra.
In Nordische, different microporous molecular sieves are developed for different applications. Most common types are zeolite, active carbon, GO and MOFs. They are mainly used for gas separation and storage, different metal extraction and water adsorbtions.
Membranes, in general, are selective barriers available in different shapes and sizes for separating gases or liquids based on different factors.
A composite membrane refers to a membrane composed of two or more layers or materials that have distinctive roles in separation. It can be of organic-inorganic moiety or inorganic-inorganic moiety like polymer-metalllic membrane, ceramic-polymeric membrane, mixed matrix membrane etc.
In Nordische, we generally deal into polymer based composite membrane, say, ceramic or zeolite or dense or other porous membranes on a support. This has a wide range of applications from gas separation, desalination, wastewater treatment, water, purification, metal extraction, storage and sequestration etc.
These are available in different sizes and shapes.
