Background

Hydrogen is a colorless and less dense gas than air (hydrogen is the least dense of the various gases-under standard conditions, 1 liter of hydrogen has a mass of 0.0899 grams, and the same volume is much lighter than air). Since hydrogen is poorly soluble in water, it can be collected by a water-gas-collecting method. In addition, hydrogen gas can be converted into colorless liquid at a temperature of-252.87 ℃ under a pressure of 101 kPa; at-259.1 deg.C, it becomes a snow-like solid. At normal temperature, the hydrogen has stable property and is not easy to generate chemical reaction with other substances. But the situation is different when the conditions change (e.g. ignition, heating, use of a catalyst, etc.). For example, hydrogen has a strong activity (particularly, adsorption by palladium) after being adsorbed by metals such as palladium or platinum. The adsorption of hydrogen by metallic palladium is strongest. When the volume fraction in the air is 4% -75%, an explosion can be caused when encountering a fire source. The existing hydrogen cooler is generally low in cooling efficiency and needs to be improved.
