　　Problems such as high costs and technical difficulties will be overcome! Hydrogen fuel cell vehicles can be scaled up by 2030

　　In the past two years, the development of hydrogen fuel cell vehicles has attracted attention from all walks of life and has gradually become a hot spot pursued by capital and companies.

　　At present, the government, academia and companies are paying close attention to the research and development and production of hydrogen energy vehicles. The central and local governments have successively introduced relevant support and subsidy policies to encourage the development of hydrogen energy vehicles. Hydrogen Cloud Chain believes that according to my country’s preliminary plan for the future development of hydrogen energy vehicles, it is expected that large-scale promotion and marketization can be achieved around 2030.

　　After years of hard work, my country has made great progress in lithium-ion batteries in the fields of hydrogen energy and fuel cell technology. In the technical fields of hydrogen preparation, storage and transportation, my country's hydrogen production industry is mainly based on imported technology. The technology is relatively mature and is comparable to that of developed countries. The difference is not big.

　　Especially in the field of fuel cell technology, my country has mastered key technologies such as catalysts, proton exchange modules, and bipolar plate materials, but there is still a big gap compared with foreign advanced technologies. However, the large-scale production of key components, batch assembly of stacks and related performance indicators lag far behind.

　　Hydrogen Cloud Chain believes that based on the current technology, cost and hydrogenation stations, it can be seen that hydrogen fuel cell vehicles should be the first to be scaled up and marketed in the field of commercial vehicles such as buses and buses.

　　The Hydrogen Cloud Chain believes that at present, the biggest challenge in developing hydrogen fuel cell vehicles is not the car itself but the upstream and downstream industrial chains of the hydrogen industry, especially in the transportation field.

　　Compared with the power lithium batteries of pure electric vehicles, the industrial chain and technology chain of hydrogen fuel lithium-ion batteries are too long. From hydrogen production, storage and transportation, hydrogenation, on-board hydrogen storage, to fuel cell stacks and engines, there are many technical links. , there are technical problems to be overcome in every link.

　　Based on the current commercialization scenario of passenger cars that is difficult to realize, Hydrogen Cloud Chain believes that prioritizing the development of fuel cell commercial vehicles is an important path for my country to achieve a breakthrough in hydrogen energy vehicles. However, to achieve the popularization of hydrogen energy commercial vehicles, it is necessary to overcome the cost bias of the entire vehicle. There are a series of problems such as high cost, immature technology, high cost of hydrogen, high cost of hydrogen refueling stations, and slow approval process.
