Proton Exchange Membrane Fuel Cell (PEMFC)

A Proton Exchange Membrane Fuel Cell (PEMFC) is a device that converts hydrogen and oxygen into electricity, with water and heat as byproducts. It works by allowing hydrogen gas to pass through a special membrane, where it splits into protons and electrons. The protons move through the membrane to the other side, while the electrons create an electric current as they travel through an external circuit. The protons and electrons then recombine with oxygen to form water. PEMFCs are known for their efficiency and are used in applications like cars, buses, and stationary power generation.
