      Nowadays, the development of fuel cell vehicles has made the domestic "hydrogen" storm in full swing. In addition to traditional fossil fuel hydrogen production methods, methanol reforming hydrogen production fuel cell technology is becoming a new favorite. At present, in our country, hydrogen production, hydrogen storage, hydrogen transportation, hydrogenation, etc. are facing a series of problems, both in terms of economy and safety. How to break through this bottleneck? Using methanol as a carrier and using methanol reforming to produce hydrogen fuel cells is one of the effective solutions. Speaking of the most significant technical features of this route, Zhou Mingqiang, chairman of China Hydrogen New Energy Technology Co., Ltd., summed it up in eight words: "safe, reliable, realistic and feasible". The methanol reforming hydrogen fuel cell uses methanol water as fuel, which is reformed into hydrogen inside the device. From safety considerations, methanol water is much higher than pure hydrogen, and methanol water is easy to store and transport. Hydrogen is produced and used at normal pressure. It does not require infrastructure such as high-pressure hydrogen tanks and hydrogenation stations. The stack used is a high-temperature stack. The general operating temperature exceeds 100°C. The hydrogen used in the stack is heavy. Because the high-temperature reactor has high CO tolerance, the reformed hydrogen can be used directly without purification. At the same time, the high-temperature reactor does not require complicated water management and temperature management, making the entire system simpler; in addition, it The modular structure is simple, has good reliability, low failure rate and is easy to maintain. Therefore, methanol reforming hydrogen fuel cell is a safe, reliable, realistic and feasible fuel cell technology. As this technology is being promoted and applied, will methanol fuel be in sufficient supply? This is the biggest concern in the industry right now. Industry insiders pointed out that my country is currently one of the countries with the largest methanol production in the world and has abundant methanol supply. First of all, from the perspective of fuel sources, the main source is coal-to-methanol. Coal-to-methanol will effectively solve the problem of direct combustion of coal that pollutes the atmosphere. Secondly, natural gas can also be used to produce methanol. Thirdly, the greenhouse gas carbon dioxide can also be recycled. It is synthesized and produced together with hydrogen; fourth, it can also be produced through biomass. Talking about the current application scenarios of "methanol reforming hydrogen fuel cell" technology, Zhou Mingqiang said vividly, "Applying this technology to transportation is equivalent to turning a small hydrogen production station on the basis of hydrogen fuel cells. Moving it into the car eliminates the problems of hydrogen fuel storage and transportation." The technical route of methanol reforming to produce hydrogen is methanol-methanol filling-methanol direct reforming to produce hydrogen fuel cell. In the battery system, methanol is liquid at room temperature, which is easy to store and transport. Hydrogen is "ready to use". The system does not have high temperature and high pressure, and the operation is safer and more reliable, with obvious advantages. It effectively breaks through the hydrogen storage, transportation and refueling links, and effectively solves the current problems of the government's difficulty in promoting hydrogen refueling stations at the application level, facilitating rapid market promotion. According to reports, methanol hydrogen fuel cell vehicles have been used in transportation fields such as buses, logistics vehicles, buses, and cold chain logistics vehicles. Industry experts said that this is a revolutionary technological breakthrough. It is not only an exploration of the use of methanol power, but also establishes the relationship between the two old and new energy eras. It is a significant step for mankind to move towards the hydrogen energy era.
