How Does a Fuel Cell Work? ⚡ | A Futuristic Electrochemical Cell Explained | Electrochemistry

A fuel cell generates electricity through an electrochemical reaction between a fuel—typically hydrogen—and oxygen. At the anode, hydrogen releases electrons, which then travel through an external circuit to produce an electric current. At the cathode, oxygen combines with protons and electrons to form water, a process that also generates heat and helps reduce environmental pollution.
