Hydrogen fuel cell industry attracts attention, fuel cell technology faces industrialization challenges

　　As a rookie in the new energy vehicle industry, fuel cell vehicles still have a long way to go in technology research and development, supporting facilities construction, and large-scale commercial applications. Facing the above-mentioned challenges, enterprises, governments and society are required to participate together to promote the development of the fuel cell vehicle industry.

　　Hydrogen fuel cell system is a set of power generation system. Through the electrochemical reaction of hydrogen and oxygen, water is discharged finally. Compared with the current mainstream lithium battery, it is more environmentally friendly. According to Battery China.com, the current lithium battery charging time is generally 30-50 minutes in the fast charging mode. Compared with the lithium battery used as an energy storage device, the hydrogen fuel cell system itself is a power generation device, supplementing fuel-hydrogen. , It only takes 3-5 minutes.

　　The development layout of the hydrogen fuel cell industry is quietly proceeding

　　Not only domestically, but the Japanese government has also made plans. By 2025, there will be a total of 200,000 hydrogen fuel cell vehicles and 320 hydrogen refueling stations; in 2030, there will be 800,000 hydrogen fuel cell vehicles and 900 hydrogen refueling stations. ; Germany mentioned in the hydrogen energy plan released in 2016 that by the end of 2018, it will invest 161 million euros to develop the hydrogen energy industry, and plans to complete 100 hydrogen refueling stations in 2023. The hydrogen fuel cell industry is valued in most countries.

　　Hydrogen refueling station and other infrastructure supporting facilities are steadily advancing

　　The hydrogen refueling station provides raw materials for hydrogen fuel cell vehicles. If the supporting facilities cannot keep up, it will seriously restrict the development of the fuel cell vehicle industry. Statistics show that as of the end of 2017, there were 327 hydrogen refueling stations in the world, mainly in Asia, Europe and North America. Before 2015, there were only 3 hydrogen refueling stations in China. By 2017, 13 hydrogen refueling stations had been put into operation. There are still 20 under construction in China, and this number is expected to exceed 100 by 2019.

　　Fuel cells have obvious advantages in the application of commercial vehicles

　　Unlike foreign car companies that start with passenger cars in the layout of fuel cell vehicles, some domestic fuel cell companies choose to start with commercial vehicles. According to Battery China.com, Shanghai Reshaping Energy Technology Co., Ltd. launched 500 fuel cell logistics vehicles in Shanghai in 2017. The company’s chairman Lin Qi revealed to Battery China.com that the company chose to enter the fuel cell commercialization market from logistics vehicles because of the following considerations: First, commercial vehicles are relatively flexible in terms of space layout for fuel cell systems; second, Commercial vehicle operating routes are relatively fixed, with fixed-point routes, and there is less demand for the layout density of hydrogen refueling stations; third, the use of fuel cells in urban public transport and logistics distribution has a certain promotion significance; fourth, it is hoped that the fuel cell commercial vehicle market will be promoted. Promote the construction of hydrogenation infrastructure and pave the way for the future passenger car market.

　　Experts in the industry said that the commercialization advantages of fuel cell technology for vehicles are that it is not sensitive to vehicle load, the mass specific power density, the volume specific power density is relatively high, and the fuel filling time is very short (about 3-5 minutes. Supplement), the cruising range and load capacity have been greatly improved, and the fuel cell system has more obvious advantages in heavy load applications and medium and heavy commercial vehicle applications. With the rapid development of e-commerce and logistics and distribution industries today, especially under the premise that large and super-large cities have greater demand for the logistics and distribution industry, and also on the premise that there are higher requirements for the urban environment, fuel cell logistics vehicles are A good one can fill the current application of new energy vehicles in the blank field of long battery life and high load.

　　Fuel cell technology industrialization challenge

　　As the most ideal energy-saving technology in the future, the industrialization and commercialization of fuel cell technology are still facing considerable challenges. According to the opinions of experts in the industry, the challenges faced by the commercial application of fuel cell vehicles are classified into the following categories:

　　First, the standard category. Fuel cell vehicles have the superior characteristics of long battery life. Long battery life means more hydrogen. At present, the 70Mpa hydrogen system standard in the hydrogen storage system needs to be broken. In the field of logistics applications, for end users, they are more concerned about operating costs, and the use requires enterprises to strengthen technology research and development in the storage and transportation of hydrogen. At the same time, the relevant standards for fuel cell vehicles also need to be improved.

　　Second, resources. The first is the construction of hydrogen refueling station facilities. The commercial application of fuel cell vehicles is inseparable from the supporting construction of hydrogen refueling station facilities. At this stage, hydrogen refueling stations are under great pressure in terms of approval and land use. The second is the autonomy of fuel cell system components. Realizing the independent development and localization of key components of the fuel cell system is a key way to reduce costs. This area requires the strong support of the supply chain and component manufacturers. The third is policy-oriented market pressure. The current new energy vehicle market is a subsidy-driven market. After there is no subsidy or subsidy declines, this pressure must be endured and there must be a solution.

　　Third, cognitive category. One is the over-interpretation related to hydrogen safety. For a long time, due to the lack of adequate understanding of hydrogen energy by the public, there are still doubts about the safety of hydrogen fuel cell vehicles. This is also a major factor in the rapid development of the hydrogen fuel cell vehicle industry. The second is the social science of fuel cell technology. Although fuel cell is also called "battery", it is different from energy storage battery. It is actually a power generation device, and its energy is actually stored in the hydrogen storage system. The third is the diversification of global technology routes. At this stage, fuel cells are still in the development stage, the market has not yet formed a scale, and the company's technical routes are still unclear. Experts believe that there are still 1-2 very clear technical routes to be determined on the technical route of fuel cells in the future.

　　As a rookie in the new energy vehicle industry, fuel cell vehicles still have a long way to go in technology research and development, supporting facilities construction, and large-scale commercial applications. Facing the above-mentioned challenges, enterprises, governments and society are required to participate together to promote the development of the fuel cell vehicle industry.
