Proton Exchange Membrane

A Proton Exchange Membrane (PEM) is a specialized material used in fuel cells to generate electricity. It acts like a selective barrier that allows protons (positively charged particles) to pass through while blocking electrons and gases. This separation directs electrons through an external circuit, creating an electric current that can power devices or vehicles. The membrane's key functions include facilitating proton transport and maintaining separation of reactants. PEMs are made from durable, conductive materials like Nafion, enabling efficient, clean energy conversion without harmful emissions. They are essential components in many modern, environmentally friendly energy systems.
