Wan Gang: seven problems of fuel cell vehicles remain to be solved

on June 28, the "hydrogen energy industry innovation and Development Forum" was held at Tsinghua University. Leaders of domestic and foreign governments and relevant departments, experts and scholars in hydrogen energy industry research, and enterprise representatives in automotive, energy, and other fields had in-depth exchanges

respected chairman Qingtai, respected Comrade Guanhua, President Qiu Yong, friends, good afternoon! I'm glad to be able to attend this forum. The topic of this forum is "breaking through core technology to create an industrial ecosystem", which is indeed a special issue that we should consider in promoting the development of electric vehicles in recent years

I would like to share with you some ideas and Thoughts on the development of fuel cell vehicles. The first is to review the development of fuel cell vehicles in our country with you from two aspects; Second, I would like to discuss with you the opportunities and challenges facing the development of fuel cell vehicles

the development of new energy vehicles in our country can be traced back to the beginning of this century and the end of last century. At that time, we were discussing the research and development of new products. Although there are still differences between the performance of our [wood plastic] composite floor and wood floor, there are three possible driving forms of energy vehicles, namely pure electric, hybrid and fuel cell driving systems. How to adapt the three possible driving forms to industrial development and future development? When it comes to industrialization, as a national science and Technology Department, we need to study the common core technologies in order to promote the development of the industry, so that new energy vehicles can promote the development step by step

at that time, we found some common core technologies from the three models, that is, power battery and management system, motor and drive system, as well as hybrid engine and fuel cell engine of hybrid system. Combining them may form three forms of vehicles, which formed the national R & D layout at that time: pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles as the three main development models. The common core technologies of these three models are power battery, drive motor and intelligent control system, as well as the drive engine system with its own characteristics of various models. I want to explain again that when we determined the major special project of electric vehicles in 2001, we made it clear that reducing energy dependence, reducing urban air pollution and promoting the leapfrog development of the automotive industry are the long-term goals of the development of new energy vehicles in our country

looking back on these years, new energy vehicles have kept pace with the times in the development process, and products and markets have developed in an orderly manner. In the tenth five year plan, we determined the R & D layout of "three vertical and three horizontal". In the eleventh five year plan, we strengthened basic research. In the 12th Five Year Plan and the 13th five year plan, we based on the intelligent driven development direction of new energy vehicles, The content of R & D is broader and deeper, especially the depth of basic research. Fuel cell engine has always been the focus of research and development. When the 13th five year plan was formulated, our country formulated many relevant development plans, including the development plan of new energy vehicles, special tasks of science and technology, energy technology revolution and various places, such as Shanghai, Suzhou, Wuhan and Shandong, which are promoting the development of new energy fuel cells in various places

in terms of basic research, automotive fuel cells have made relatively smooth progress. Fuel cell materials have been significantly improved. These are several enterprises I visited recently. Xinyuan power of Dalian Institute of chemical industry, Chinese Academy of Sciences, yihuatong, an emerging fuel cell enterprise, and Shanghai Versailles, these three enterprises all chose the same path: 30kW drive module, 60kW drive module, and 120kw drive module. Their stack power density has reached 2kW/L

in retrospect, we launched the first batch of fuel cell vehicles in our country at the 2008 Olympic Games to provide transportation services and stadium services for the Olympic Games, which attracted the attention of the world at that time. I remember that there are more than 20 fuel cell cars and more than 10 fuel cell buses. This number has developed greatly by the 2010 WorldExpo. There are more than 200 fuel cell buses, cars and venue vehicles running in the Expo. We participated in the world competition, conducted a fuel cell vehicle demonstration application in Beijing, and also participated in the commercial operation test of fuel cell vehicles in California. Now the domestic commercial demonstration operation has spread all over many places. In addition, Shanghai Dongfeng Peugeot Citroen, Henan Yutong, Zhongtong and Dongfeng have all developed sample vehicles and conducted demonstrations. According to the statistics of Professor Wang Hewu of Tsinghua University, there are nearly 1000 vehicles in operation, 12 hydrogenation facilities in operation and nearly 10 under construction

hydrogen fuel cells can also be applied to many fields. For example, there are more than 100 backup power supplies for base stations around Shanghai. During the four to five years of operation, they have maintained stable operation and achieved good results. At the same time, fuel cells can also be used as backup power for IDC machine rooms, hospital emergency rescue systems, security and deep submergence systems. Based on these, our enterprises began to participate in the research and development of fuel cells. As early as 2007, SAIC started the development of fuel cells on the basis of early research and development. In 2014, it carried out a nationwide ten thousand mile trip, recently developed commercial vehicles, and formulated the 13th five-year plan to achieve the strategic goal of fuel cell development by 2020

we have carried out bilateral and multilateral international cooperation. The international hydrogen energy economic partnership program was launched at the clean energy ministers' meeting last year. It is hoped that the electric vehicle composed of isooctyl acrylate monomer can reach 30% by 2030. In terms of bilateral cooperation, cooperation has been carried out between the China us clean energy vehicle research center and the China Germany electric vehicle research center. With the support of the United Nations Environment Program, China has carried out a three round fuel cell vehicle joint demonstration project. At the same time, we have also taken the initiative to initiate and organize the international hydrogen fuel cell association

in general, China has made significant progress in fuel cell vehicles. In terms of the technology of fuel cell vehicles, the feature of fuel cell vehicles in China is the electric electric hybrid system, which is not only in line with the technical characteristics of fuel cells, but also suitable for the industrial points of technological innovation in our country. In terms of the whole distribution, from pure electric to systems with partial electric power and partial fuel cell drive, it can be divided into several categories. One is energy hybrid, which is dominated by pure electric vehicles and supplemented by fuel cells. There is also a kind of fuel cell, which is mainly used to supplement its drive with power battery. These two types have development prospects. But in general, the biggest feature of fuel cell vehicles in China is electric electric hybrid

in the past ten years, with the support of the national science and technology plan and the industrial technology innovation project, our country has carried out the research, development, demonstration and operation of hydrogen fuel cell vehicles, initially forming a fuel cell stack system, vehicle R & D system and manufacturing capacity, and carried out the demonstration operation of the system

next, I want to discuss with you the opportunities and challenges of promoting the development of fuel cell vehicles. At present, new energy vehicles have become a symbol of the transformation and upgrading of the global automotive industry. According to the data of China Automobile Association and markliens, the sales of new energy vehicles in major countries in the world exceeded 1.42 million in 2017, and the sales volume in China reached 777000. The cumulative sales volume of new energy vehicles in the world has exceeded 3.4 million, and China accounts for more than 50%. That is to say, the goal we set in that year has made new contributions to energy conservation and carbon reduction and to coping with climate change. In terms of the distribution of models, passenger cars, passenger cars, cars and commercial vehicles began to grow, and the proportion of passenger cars exceeded that of commercial vehicles. China's fuel cell buses began to be gradually applied in cities

the commercialization and industrialization of our fuel cell vehicles are still lagging behind. In particular, the industrial ecology and market have not yet been built, and there are probably seven obvious problems

first, the progress of industrialization and commercialization is significantly backward; Second, some key technical problems cannot be solved for a long time, and the gap is obvious; Third, the industrial chain is relatively weak and the engineering capacity is insufficient; Fourth, the main role of enterprises is missing; Fifth, the systems of hydrogen production, hydrogen supply and hydrogenation are relatively backward, resulting in a sharp increase in the cost of hydrogen; Sixth, the technical standards and testing system are seriously lagging behind; Seventh, international opening-up and cooperation still need to be strengthened. Now let me talk about the ways to solve these problems in the future

first, the progress of industrialization and commercialization lags behind, indicating that although there are a large number of new energy vehicles, they mainly operate within the scope of cities. The main shortcomings are driving range, charging time and energy density. From the perspective of market, the proportion of long-distance buses between urban buses and urban wide vision in China is about 1:6, that is, a city bus has about 6 times the long-distance bus. These long-distance buses operate point-to-point, with short stopping time, little charging time left, and high environmental protection requirements. From the city center to the center of another city, the traffic volume demand is also relatively large. The second is the city taxi. There are many private electric cars or public electric buses in cities, but taxis between cities, especially those in megacities, such as Beijing, generally operate in double shifts. I went to Hong Kong a few days ago. The taxi runs a long day, so it is difficult to have a long time to recharge, so they hope to be able to recharge for a shorter time. Third, with the development of purchasing, there is a great demand for urban logistics vehicles, but its operation intensity is relatively high and its mileage is relatively long. In the medium and long term, medium-sized and heavy-duty trucks are a development direction. This time, the backward diesel engine is clearly taken as a direction in the battle against pollution prevention. Medium and heavy-duty trucks have long mileage and high environmental requirements. A good way to solve these problems is fuel cell vehicles. Today, the shortcomings of electric vehicles can be fully complemented by fuel cell vehicles and hydrogen energy

second, many key problems cannot be solved for a long time. Although we have deployed a series of studies as early as the beginning of this century, there has been no significant progress on some key issues, and the gap is obvious. For example, the power density of the stack is basically about 2kw/l for domestic products; It is reported that the international advanced level has reached about 3kw/l. In terms of catalyst efficiency, the domestic platinum consumption per kW is about 0.3 g; It is reported that the international advanced level has reached below 0.06g. In terms of membrane electrode durability, the measured service life under domestic dynamic conditions is about 3000 hours; It is reported that it has reached 9000 hours abroad. In terms of air compressors, domestic fuel cell products now basically adopt low-pressure compressors, while foreign countries mainly adopt high-pressure air compressors. If the pressure can be doubled, its efficiency may be increased by 50%. But I think recently
