ELI5: Explain Like I'm 5

Home fuel cell

A home fuel cell is like a mini power plant you put in your house. It's like an electric power plant that is smaller and uses special fuel like natural gas or hydrogen to make electricity. Inside the fuel cell, special chemicals mix with oxygen and the fuel to create a reaction that makes an electric current. Then this electricity is used to power your house just like what comes out of the electric outlets.
