Description

Technical Field

[0002] Hydrogen is not only the most abundant element in the universe, it is also the main element of nuclear fusion, which provides energy for the sun and is the basis of all life on Earth. It is also a key element in all fossil fuels that have driven business, industry and living standards since the first industrial revolution. In addition, compared with fossil fuels, hydrogen energy has two key advantages in the field of mobile travel applications. On the one hand, hydrogen is clean. It releases energy through oxidation and only produces water as a by-product. On the other hand, hydrogen is sustainable. As long as the sun rises as usual, it can be infinitely renewable.

In addition, the sealing performance at the connection between the water inlet pipe and the water outlet pipe and the tank surface is not high, which can easily cause hydrogen leakage inside the tank for a long time, causing waste and reducing safety.
