PEM Fuel Cells

PEM (Proton Exchange Membrane) fuel cells are devices that generate electricity through a chemical process using hydrogen and oxygen. They consist of layers including a membrane that allows protons to pass through while blocking electrons. When hydrogen gas enters, it splits into protons and electrons; the electrons travel through an external circuit to produce electricity, while the protons move through the membrane to combine with oxygen on the other side, forming water. This process creates clean, efficient power without combustion, making PEM fuel cells a promising technology for clean transportation and energy applications.
