Explanation:

A fuel cell is composed of an anode, a cathode, and an electrolyte membrane. A fuel cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. At the anode site, the hydrogen molecules are split into electrons and protons. The protons pass through the electrolyte membrane, while the electrons are forced through a circuit, generating an electric current and excess heat. At the cathode, the protons, electrons, and oxygen combine to produce water molecules.

Due to their high efficiency, fuel cells are very clean, with their only by-products being electricity, excess heat, and water. In addition, as fuel cells do not have any moving parts, they operate near-silently.
