polymer electrolyte membranes

Polymer electrolyte membranes are special materials used in fuel cells to conduct charged particles (ions) while blocking others, enabling efficient energy conversion. They are thin, flexible sheets made of polymers—long-chain molecules—that facilitate the movement of ions like protons. These membranes separate the fuel and oxygen in the cell, allowing a chemical reaction that produces electricity, water, and heat without direct combustion. Their key qualities include high electrical conductivity, durability, and chemical stability. Used in clean energy applications, such as hydrogen-powered vehicles, these membranes play a vital role in creating sustainable and efficient energy solutions.
