At the heart of methane fuel cell technology lies a complex series of chemical reactions, meticulously converting methane into electrical power. Comprised of fundamental components including the anode, cathode, and electrolyte, methane fuel cells operate through precise chemical reactions:

Anode Reaction: Methane (CH4) is supplied to the anode, where it undergoes a chemical reaction that splits the methane molecules into carbon dioxide (CO2) and water (H2O). Simultaneously, electrons are released as part of this process.

Electron Flow: The released electrons travel through an external circuit, creating an electrical current. This flow of electrons becomes the basis for generating electrical power.

Cathode Reaction: Oxygen from the air is supplied to the cathode, where it reacts with the electrons and protons that have migrated through the electrolyte. This reaction produces water as a byproduct, closing the energy loop.
