What is hydrogen?

Hydrogen is a kind of elemental form of hydrogen, with chemical formula H₂ and molecular weight of 2.01588. At normal temperature and pressure, hydrogen is a colorless, tasteless, highly combustible and insoluble gas in water. Hydrogen has a density of 0.089g/L (101.325kpa,0°C), which is only 1/14 of that of air, making it the least dense gas known in the world.

What is a hydrogen sensor?

Hydrogen sensor is very sensitive to hydrogen at room temperature and has good selectivity, which can be used as a sensor to detect hydrogen concentration in the environment. Due to the safety requirements in production and life, fast, sensitive and accurate hydrogen sensor is very necessary to avoid the possibility of explosion in time.

What are the applications of hydrogen?

1. The use of hydrogen is determined by the nature of hydrogen. For example, hydrogen is the least dense of all gases and can be filled into a sounding balloon.

2. Hydrogen can be inflatable ball or air boat, used as heat conduction material in the dihydrogen internal cold generator, smelting non-ferrous metals and high purity germanium, silicon, synthetic ammonia, hydrochloric acid, petroleum hydrogenation, hardening oil, high efficiency fuel, hydrogen and oxygen flame.

3. Hydrogen is the lightest gas and is most commonly used to fill hydrogen balloons and airships. Hydrogen is an important chemical raw material.
