Development and application of new energy is a major research topic in today's global, this article is mainly written application of hydrogen energy!

  ① advantages of hydrogen as an ideal energy future a. Wide range of sources of hydrogen can be obtained from water system. b. Hydrogen combustion heat value higher than fossil fuels (see below). Approximately twice the calorific value of gasoline. c. The most prominent advantage is the combustion product is water, do not pollute the environment and therefore hydrogen has broad development prospects. Best hydrogen generator kits online provider.

  ② nature of hydrogen a. Physical properties of hydrogen: Typically, hydrogen is a colorless, odorless gas that is insoluble in water, the density is 0.089g / L, small density than air, is the lightest gas. b. Chemical properties of hydrogen: hydrogen Flammability: pure hydrogen be quiet combustion in air, the chemical equation for the reaction 2H2 + O22H2O, phenomena of: generating a light colored flame monitoring, the heat release hydrogen reducing Hill: Hydrogen under the heating conditions, reaction of certain metal oxides sorted seize metal oxide O, and therefore, the hydrogen gas having reducing properties, i.e., the loss of the metal oxides can be reduced to O and metal reducing agent is hydrogen gas is an important . Such as hydrogen reduction of copper oxide: H2 + CuOCu + H2O Phenomenon: black solid powder gradually turns red, the tube wall with drops of water to produce. 

  ③ hydrogen energy development a water electrolysis method: consume too much electricity, high cost, not the economy, not on a large scale to produce hydrogen.  hydrogen gas combustion with fast delivery and best service here. b ideal hydrogen production method: finding the right light decomposition catalyst, so that the water-splitting to produce hydrogen in sunlight exposure, 

  ④ hydrogen storage: Because Hydrogen is a flammable gas, hard liquefaction, storage and transportation is not convenient nor safe. How to store hydrogen is another key issue to develop hydrogen energy research. At present, it was found that certain metal alloys such as Ti-Fe, Ti-Mn, La-Ni, etc. have the hydrogen storage functions. Which La-Ni alloy at room temperature, 0.152MPa can emit hydrogen, have been used for storage, research and practical applications of hydrogen fuel cell cars and hydrogen new hydrogen storage alloy material has great significance for the development of hydrogen energy.
