A fuel cell vehicle is like a car that uses a special type of battery to run instead of gasoline. It's powered by a thing called a fuel cell, which makes electricity by combining hydrogen (a type of gas) and oxygen from the air.
The fuel cell takes the hydrogen and splits it into protons and electrons. The protons go one way and the electrons go another, creating electricity that powers the car. The waste product is water, which comes out of the back of the car as clean exhaust.
Like a regular car, a fuel cell vehicle has a tank that needs to be filled up, but instead of going to a gas station, you go to a special place or station that has a pump that fills the car up with hydrogen gas. These stations are not as common as gas stations right now, but there are plans to build more in the future.
Fuel cell vehicles are important because they are environmentally friendly since they don't release harmful pollutants into the air. They're also energy-efficient since fuel cells can convert hydrogen into electricity more efficiently than a traditional gas engine. And ultimately, they provide a clean and sustainable transportation option that could help reduce our dependence on fossil fuels.
