Proton Exchange Membrane Fuel Cells
Proton Exchange Membrane (PEM) Fuel Cells generate electricity by combining hydrogen with oxygen. The hydrogen gas is split into protons and electrons; the membrane allows protons to pass through but blocks electrons. The electrons travel through an external circuit, creating electricity used to power devices or vehicles. The protons move through the membrane to the oxygen side, where they combine with electrons and oxygen to form water. This process produces clean energy with water as the only byproduct, making PEM fuel cells an efficient and environmentally friendly technology for producing electricity, especially in transportation and portable power applications.
