The fire is fueled by oxygen in the air. There is no significant amount of hydrogen gas found in the atmosphere.
Does the question relate to a laboratory experiment involving hydrogen gas? Or is the question a general one? Oxygen is not a fuel, but it is required to support combustion, or rapid oxidation. Hydrogen is combustible and can be used as fuel. If you burn hydrogen, the fire is being fueled by the hydrogen, not the oxygen, but without O2, the hydrogen would not burn.

Does fire need air to breathe?
Fire needs oxygen to burn.
What gas in the air do you need to make fire?
Oxygen. It supports combustion.
Why do you need oxygen in space to make fire?
Fire needs oxygen no matter where it is. It is a chemical reaction between oxygen and some flammable substance. On Earth, the air is already 21% oxygen, so you only need to supply the fuel. In space there is no air and thus no oxygen, so you need to bring oxygen or some comparable oxidizer with you.
What is a Source of oxygen for a fire?
the air
What is an oxygen fed-fire?
An oxygen-fed fire is a fire that has (most likely) pure oxygen fueling it. The air we breathe is composed of around 19% oxygen, therefore by adding more oxygen the fire will get hotter.
Why does fire need air?
Fire needs the oxygen in the air. Any other source of oxygen would also sustain fire.
Do you need air to have a fire?
Yes you need air. Or more correctly oxygen.
Does fire need air to breathe?
Fire needs oxygen to burn.

Oxygen. It supports combustion.

How you use nitrogen gas to control fire in mine?
A fire needs oxygen to burn. Air contains oxygen. So passing in nitrogen stops incoming air refuelling the fire. Have to be careful if there are trapped people who of course need to take in oxygen as they breathe.
How does fire affect air?
Part of air is made up of oxygen without which fire can't happen. Air can feed a fire; it contains oxygen.
What is the source of oxygen for a fire?
the air
What is a Source of oxygen for a fire?
the air
Why does the flame get hotter when the air inlet is correctly set?
more oxygen is flowing to the flame, to create fire you need heat, fuel and oxygen.
What is an oxygen fed-fire?
An oxygen-fed fire is a fire that has (most likely) pure oxygen fueling it. The air we breathe is composed of around 19% oxygen, therefore by adding more oxygen the fire will get hotter.
What three elements are needed to have a fire?
no what you need to have to start to start a fire is lots of diff stuff you need fuel... like wood, dry grass or tinder paper. Air...oxygen. Heat ... fire!
