Expert Answer:

Hydrogen is a very combustible element in the presence of oxygen, but it does not support combustion as oxygen does.

Let us see I brief the nature of hydrogen which does not allow substances to burn in it with the help of an experiment.

Consider a jar filled with hydrogen with inverted mouth downwards and introduce a burning candle near the mouth of jar, the gas burns at the mouth of the jar while the burning candle gets put off. This shows that hydrogen is combustible but not a supporter of combustion.
