Solid oxide fuel cell

A solid oxide fuel cell is a special device that turns fuel (like natural gas or hydrogen) and oxygen from the air into electricity. Imagine putting some small batteries together to make a bigger battery. That’s sort of like what a fuel cell does!

The inside of a fuel cell has special materials called electrodes and an electrolyte that help turn the fuel and oxygen into electricity. The electrodes are like two sponges on either side of a sandwich, and the electrolyte is like the filling that holds them together.

When you connect the electrodes to a circuit (like when you turn on a light bulb), the fuel and oxygen react and flow in a certain direction, creating an electric current that can power things. So the fuel cell is like a sandwich that makes electricity when you add fuel and oxygen and connect it to a circuit.

But unlike a regular battery, a fuel cell keeps making electricity as long as you keep feeding it fuel and oxygen. That's why fuel cells are used to power all types of things like cars, homes, and even big buildings because they are really good at making energy efficiently and reliably without creating pollution.
