Explanation:
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element in the periodic table. At standard conditions hydrogen is a gas of diatomic molecules having the formula H₂. It is colorless, odorless, non-toxic, and highly combustible. hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. ...

Hydrogen fuel cells produce electricity by combining hydrogen and oxygen atoms. The hydrogen reacts with oxygen across an electrochemical cell similar to that of a battery to produce electricity, water, and small amounts of heat. Many different types of fuel cells are available for a wide range of applications.
Hydrogen can be used in fuel cells to generate electricity, or power and heat. Today, hydrogen is most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets.
