Hydrogen is the frist element in the periodic table of chemical elements, hydrogen is the smallest molecule knoen in nature, generally exists in a gas state, hydrgen is lighter than air because of its small molecular weight, can br filles into a hydrogen balloon as a carrier anf flight tool, hydrogen movement speed, strong penetration, high temperature and high pressure can penetrate more than 10 centimeters thick steel plate. Strong penetration is an important feature of hydrogen, because of this feature, hydrogen is more difficult to store, so after the hydrogen is dissolved in water, if you want to maintain the concentration of hydrogen in wwater for a long time, you need to use aluminum alloy materials to make packaging, other just and glass, plastic, etc., can not prevent hydrogen escape, on the other hand, because hydrogen is very small and strong penetration. After it enters the human body, it is very easy to reach various parts of the body and the interior of tissue cells, for example, hydrogen can reach the fine struct ures such as mitochondria in the cell, and fundamentally adjust the cell stste, which is an advantage that many drugs cannot achieve.
