Welcome to our video on how hydrogen fuel cells work! We'll explore the science behind this clean energy technology, from its basic components to its real-world applications.

A hydrogen fuel cell is an electrochemical device that converts chemical energy from hydrogen and oxygen into electricity, water, and heat. Let's look at the key components.

At the anode, hydrogen molecules split into protons and electrons. The electrons flow through an external circuit, generating electricity. At the cathode, oxygen combines with the protons and electrons to form water.

The overall chemical reaction is simple: two molecules of hydrogen plus one molecule of oxygen produce two molecules of water and electricity.

This diagram shows the flow of electrons and protons within the fuel cell, illustrating the electrochemical process.

Hydrogen fuel cells have various applications, most notably in electric vehicles, offering a clean alternative to gasoline-powered cars.

Hydrogen fuel cells offer high efficiency, ranging from 40% to 60%, and are a promising technology for a sustainable energy future.
