How does a fuel cell convert chemical energy to electrical energy?

Answer 1

A fuel cell converts chemical energy to electrical energy through an electrochemical reaction. The fuel cell consists of an anode (negative terminal) and a cathode (positive terminal) separated by an electrolyte. Fuel (such as hydrogen) is fed to the anode and oxygen is fed to the cathode. At the anode, hydrogen is split into protons and electrons. The protons move through the electrolyte to the cathode, while the electrons flow through an external circuit, creating an electric current. At the cathode, the protons and electrons combine with oxygen to form water, releasing energy in the process.
