Proton Exchange Membrane Fuel Cell

A Proton Exchange Membrane (PEM) fuel cell is a device that converts hydrogen gas into electricity through a clean chemical process. It uses a special membrane that allows protons (hydrogen ions) to pass through while blocking electrons. The electrons travel through a circuit, creating electrical power, while the protons move across the membrane to combine with oxygen from the air, forming water as the only waste. PEM fuel cells are efficient, produce zero emissions, and are used in applications like vehicles and portable power, offering a sustainable alternative to traditional combustion engines.
