Expert Answer
Hydrogen has the highest calorific value so it can be considered as the best fuel but it is highly inflammable.
Hydrogen is an energy carrier. This energy can be delivered as fuel cells and batteries.
There is a redox reaction in a hydrogen fuel cell and it is used to generate electricity.
In an electrochemical cell, energy can be used with high efficiency.
In many cells, hydrogen is also used as an electron donor. It can get oxidized in the presence of a catalyst.
It is also used as fuel in spacecraft.
