How Hydrogen Fuel Cells Work: Understanding the Electrochemical Process
According to ResearchGate, the above diagram illustrates the working of hydrogen fuel, showcasing the process, key components, and mechanisms involved in sustainable energy generation.
A hydrogen fuel cell operates by combining hydrogen gas (H₂) with oxygen (O₂) from the air in an electrochemical reaction. This process occurs in three main stages:
- Anode Reaction: Hydrogen molecules are split into protons and electrons at the anode.
- Electrolyte Passage: Protons pass through the electrolyte membrane, while electrons travel through an external circuit, generating electricity.
- Cathode Reaction: At the cathode, electrons, protons, and oxygen combine to form water and heat as byproducts.
This clean energy process produces only water vapour and heat, making it an environmentally friendly alternative to traditional combustion engines.
