Automobile enterprises have stepped up research and development and accelerated the marketization of hydrogen fuel cell vehicles. Houzhongjun, chief engineer of Dalian Xinyuan Power Co., Ltd., said that the development of hydrogen fuel cell vehicles has been promoted from technical breakthrough to the current "cost reduction" stage. At present, the production technology of hydrogen fuel cell has matured, and the year will be the market introduction period of hydrogen fuel cell vehicles. After 2020, hydrogen fuel cell vehicles will be fully commercialized

at this year's Beijing International Auto Show, Toyota, Honda, Hyundai, SAIC and other enterprises competed to display the newly developed hydrogen fuel cell models, which became a beautiful scenery among nearly 80 new energy exhibition vehicles

experts said that the relevant automobile enterprises have continued to invest in recent years and increased the research and development of hydrogen fuel cell vehicles, which has significantly reduced the cost of the whole vehicle, and the performance indicators have approached the commercialization level. As an important part of new energy vehicles, the marketization process of hydrogen fuel cell vehicles is accelerating

accelerate the marketization of hydrogen fuel cell vehicles houzhongjun, chief engineer of Dalian Xinyuan Power Co., Ltd., said that the development of hydrogen fuel cell vehicles has been promoted from technical breakthrough to the current cost reduction stage. At present, the production technology of hydrogen fuel cell has matured, and the year will be the market introduction period of hydrogen fuel cell vehicles. After 2020, hydrogen fuel cell vehicles will be fully commercialized

compared with traditional vehicles, hydrogen fuel cell vehicles have many advantages, such as zero emission or near zero emission, reducing water pollution caused by engine oil leakage, reducing greenhouse gas emissions, improving fuel economy, improving engine combustion efficiency, stable operation and no noise. The hydrogen fuel cell vehicle drives the engine to run through the electricity generated by the chemical reaction between hydrogen and oxygen in the air, so as to drive the vehicle. Unlike electric vehicles, which use the stored electricity to drive the vehicle, hydrogen fuel cell vehicles drive while generating electricity. During the driving process, only water is discharged, and no harmful gas polluting the air will be produced. In addition, the energy density of hydrogen is 10 times that of on-board lithium-ion batteries. A single charge of hydrogen can drive a longer distance. The energy conversion efficiency of fuel cells is times higher than that of internal combustion engines

according to experts, hydrogen fuel cell vehicles are not only clean, but also light and fast. For example, a vehicle with a storage mileage of 400 kilometers only needs a 50 kW fuel cell stack and about 5 kg of hydrogen. At the same time, hydrogen fuel cells can also solve the problem of long charging time of pure electric vehicles. For example, the hydrogen fuel cell model currently developed by Mercedes Benz is based on class B F-CELL, and the power system is jointly developed by Daimler, Renault Nissan and Ford. The carbon fiber hydrogen tank can be filled up in three minutes

Hou Zhongjun said that in the past two years, the international hydrogen fuel cell technology has made rapid breakthroughs, which are mainly reflected in: first, the service life problem has been solved, and the mainstream level can operate for 5000 hours without maintenance, while UTC and Toyota can operate for 10000 hours, which is equivalent to a lifetime maintenance free vehicle. Second, the low-temperature performance has been solved, and a brand of hydrogen fuel cell vehicle has no problem in the Arctic test. Third, the material system has made breakthroughs. For example, the amount of catalyst has been greatly reduced, the electrode plate has developed from the first generation of carbon plate to the second generation of ultra-thin and ultra-light stainless steel plate, and the safety of hydrogen storage device, hydrogenation high-pressure gun and hydrogen purity have been solved

hydrogen fuel cell vehicles have certain commercialization conditions, that is, the two key assembly components of fuel cell stack and hydrogen tank have been industrialized. Xuyanhua, Deputy Secretary General of China Automobile Industry Association, said. The real launch of the hydrogen fuel cell vehicle market must meet three conditions at the same time: the vehicle cost is greatly reduced; Market factors (such as high oil prices) or government policies provide significant incentives for zero emission vehicles; The construction of hydrogenation network is sufficient to meet the daily use needs of fuel cell vehicles

domestic enterprises should catch up

wangbinggang, leader of the National 863 energy saving and new energy vehicle major project supervision and consulting expert group, said that the design life of hydrogen fuel cells should reach 5000 hours to meet the industrialization target. The stable life of hydrogen fuel cells of relevant domestic enterprises is still about 2000 hours, while the international advanced technology has reached about 8000 hours. In addition, the high cost of hydrogen fuel cell vehicles is a common problem that global automotive enterprises need to face, and China has also drawn a large gap in this field

xuyanhua believes that there is still a considerable gap between the development of domestic hydrogen fuel cell vehicles and that of Japan, the United States and Europe. As far as the product preparation stage is concerned, China is basically in the sample development stage, and the engineering development is still in the initial stage; In terms of key technical indicators such as driving range, hydrogen consumption, low temperature performance and service life, it is at least 30% behind the international leading enterprises; The conditions for industrialization of hydrogen fuel cell stacks and hydrogen storage tanks are basically not available, and there is currently no construction plan for hydrogen refueling stations at the national level; From the perspective of R & D carried out by automobile enterprises, SAIC has a R & D team of about 300 people, with an annual development investment of about 100million yuan in recent years, and has formed a certain development capacity of electric stack and hydrogen fuel cell system. Other enterprises have carried out some basic technology research with a small amount of investment, but most of them have not carried out the research and development of hydrogen fuel cell vehicles

it is understood that as early as around 2000, the Ministry of science and technology began to support the research and development of basic technologies for domestic hydrogen fuel cell vehicles. A small number of demonstration vehicles have been put into use during the Beijing Olympic Games. In 2012, Tongji University, Tsinghua University, Dalian Institute of physical chemistry, Chinese Academy of Sciences, SAIC, FAW, etc. initiated the establishment of China's fuel cell vehicle technology innovation strategic alliance, which aims to focus on the advantages of fuel cell vehicle R & D and production, overcome relevant core and bottleneck technologies as soon as possible, and accelerate the industrialization of fuel cell vehicles in China. In the energy saving and new energy vehicle industry development plan (year), it is also clearly proposed that the fuel cell vehicle and vehicle hydrogen energy industry should develop synchronously with the world

there are signs that relevant domestic enterprises are accelerating the R & D and promotion of hydrogen fuel cell vehicles

at the end of March this year, SAIC Motor Co., Ltd. and Volkswagen AG signed a joint statement. The two sides will carry out hydrogen fuel cell technology cooperation and work with Shanghai Volkswagen to accelerate the industrialization of plug-in hybrid vehicles

at this year's Beijing International Auto Show, SAIC unveiled the Roewe 950 plug-in hydrogen fuel cell car. The vehicle is equipped with two 700bar hydrogen cylinders, with a hydrogen storage capacity of 4.34 kg and a maximum range of 400 km. By optimizing the vehicle starting system, the vehicle can still start and drive normally even in the environment of minus 20 ℃

xuyanhua said that from the perspective of the development status of domestic hydrogen fuel cell vehicles, it is possible to keep pace with the international advanced level only by catching up. In this regard, xuyanhua suggested that domestic enterprises with foundation and conditions should take hydrogen fuel cell vehicles as a long-term strategy, increase investment in oil return valves without oil outflow, and have professional teams to speed up the process of engineering development; Strengthen cooperation among enterprises, universities and research institutions, especially international cooperation, and actively participate in the formulation of relevant international standards; Relevant government departments should actively promote the industrialization of hydrogen fuel cell vehicles, including supporting the industrialization of key assembly components such as electric stacks and hydrogen tanks. At the same time, systematic and long-term consideration should be given to the construction of hydrogen refueling stations, and planned and step-by-step demonstration operations should be carried out in the field of public transport and large cities (such as Beijing, Shanghai, Guangzhou, etc.) to actively guide the development of hydrogen fuel cell vehicles

layout of multinational automobile enterprises

in recent years, Toyota and BMW, Daimler and Ford, Nissan Renault, Honda and general motors have formed alliances to accelerate the research and development of a new generation of hydrogen fuel cell vehicles. Xuyanhua believes that it is unrealistic for these multinational automobile enterprises to establish a hydrogen fuel cell automobile development alliance to completely stop the use of plastic bags. There are two considerations: one is technical complementarity and greatly reduce their development costs; the other is to share the supplier resources of key components

at the same time, Germany, the United States, Japan and other countries are implementing the future planning of hydrogen energy industrialization, focusing on the development of hydrogen fuel cell vehicles and highway hydrogenation. Wangxianmu, senior development manager of polyurethane department, introduced in detail the utilization station of polyurethane in pipeline insulation at the meeting. With the support of governments and the promotion of industries, BMW, general motors, Toyota and other major global automobile enterprises have made technical reserves in advance

at this year's Beijing International Auto Show, Toyota exhibited a FCV concept car equipped with hydrogen fuel cells. Toyota plans to launch a new fuel cell vehicle in Japan, the United States and Europe in 2015, and hopes that the annual sales of this model will exceed 10000 by 2020

a hydrogen fuel cell vehicle under development by Honda is expected to be launched in 2015. The vehicle can travel about 310 miles (about 500 kilometers) once filled with hydrogen, twice the current mileage of pure electric vehicles. Honda has set a sales target of selling 5000 vehicles within five years. The sales target markets are mainly in Japan, the United States and Europe; Mercedes Benz plans to launch a new hydrogen fuel cell vehicle in 2017; Hyundai is also building a new ix35 hydrogen fuel cell vehicle, which is expected to be mass produced and launched in 2014

the industry believes that hydrogen fuel cell is a very good energy solution for modern vehicles. At present, in Germany, the United States, Japan and other countries with developed automobile industry, hydrogen fuel cell vehicles have begun to layout
