Hydrogen can be used as a fuel give reason

Dear Student
Hydrogen has many advantages as a fuel. It produces greater amount of energy than other fuels such as diesel, petrol, CNG.
It is a clean fuel as it does not produce gases that cause pollution ( like carbon monoxide, carbon dioxide, sulphur dioxide etc).
It produces water on combustion with only traces of nitrogen oxide. Its uses are:
1) As a rocket fuel in space research.
2) It is used in Fuel Cells (type of galvanic cells). The energy produced on its combustion is used to generate electricity.
3) It is also being used as an alternative fuel in some motor vehicles. However, this is not so common as it is highly flammable.
