Ouyang Minggao pointed out that the development of hydrogen fuel cells and the development of hydrogen fuel vehicles can not be equated, hydrogen fuel cells are a large range. In the automotive industry, mainly used in commercial vehicles , in addition to automobiles, hydrogen fuel cells have many uses, such as aircraft, trains, ships, power generation, and energy storage. We should look at hydrogen fuel cells from an energy perspective, not just from a car perspective. Fuel cell technology and hydrogen energy technology are two areas that are interrelated but still different. Fuel cells are a power issue and hydrogen energy is a fuel issue. Just like the engine and refueling of a traditional car, one is the thing of the auto industry, and the other is the matter of the energy industry. It used to be separate, and now the same is true for hydrogen energy. Ouyang Minggao pointed out that if our fuel cell is ten years later than the development of power battery, from the perspective of technological innovation, hydrogen energy is much later than fuel cell, so the most important thing at present is hydrogen energy technology. , all-round development and improvement of industry and policy. The first thing we need to do now is technological innovation, such as a new generation of hydrogen production technology. Who should do this? Ouyang Minggao believes that it should be done by Sinopec, the National Energy Group, the national power investment and chemical industry, and now they are all very interested, this is right. . With regard to hydrogen energy itself, the technical challenges now face are much larger than those of fuel cells, both in terms of technology and policy. From a technical point of view, the fuel cell technology for vehicles should gradually mature in the next five years or so. But today's hydrogen energy technologies, such as hydrogen production, hydrogen storage, hydrogen transport, etc., are many processes many years ago, which require technical updates, because these processes are low in energy efficiency and high in cost, which is not ideal. Ouyang Minggao said that the two technologies of lithium battery and fuel cell are not contradictory and are not a substitute. China has developed pure electric vehicles for ten years, and there are many experiences and policies that can be used for reference. He believes that the time node for the full development of fuel cells should be ten years later, because fuel cells are ten years later than the development of pure electric lithium batteries, just like the lithium battery just started a decade ago, but after ten years of development, pure electric has developed. It is very rapid. It is estimated that after 3-5 years, the problems that are plaguing us can be solved. We must look at this matter with a developmental perspective.
Shinyfly Quick connector is composed of body, in O-ring, spacer ring, out O-ring, securing ring and locking spring. When inserting another pipe adapter(Male End Piece) into the connector, since the locking spring has certain elasticity, the two connectors can be connected together with the buckle fastener, and then pull back to ensure the installation in place. In this way, the quick connector will work. During maintenance and disassembly, first push in male end piece, then press locking spring end till expansion from the middle, the connector can be easily pulled out. Lubricated with SAE 30 heavy oil before re-connecting.
