At the 2014 China Automotive Industry Development (TEDA) International Forum, Wan Gang, vice chairman of the National Committee of the Chinese People's Political Consultative Conference and Minister of Science and Technology, revealed that the Ministry of Science and Technology has recently launched the “13th Five-Year†Electric Vehicle Technology Plan, with the goal of 5 The whole factor competition for the development of new energy automobile industry will lay the foundation after the year.
At the meeting, the Minister of Science and Technology Wan Gang said that the “13th Five-Year†electric vehicle technology plan specifically deployed the development of fuel cell vehicles, and plans to increase R&D and investment in key infrastructure devices, fuel cell systems, infrastructure and demonstration. In the next few years, it is necessary to overcome the surface modification technology of thin metal bipolar plates, the durability technology of fuel cells for vehicles, the construction of hydrogen refueling stations and the demonstration operation of fuel cell vehicles.
The advantages of fuel cell vehicles are obvious. Not long ago, Toyota announced that it will be the first to mass-produce fuel cell vehicles worldwide at the end of this year. In order to make a good development opportunity, the overall expert group leader of the National 863 Program Energy Conservation and New Energy Vehicles Major Project Ouyang Minggao said at the meeting that the relevant departments have now formulated the technical roadmap for the development of fuel cell cars in China, and the above steam A detailed timetable for the development of the model was developed for the pilot.
It is understood that the fourth generation of fuel cell vehicles launched by SAIC in 2016 will be controlled at around 250,000 yuan.
In addition, Ouyang Minggao also revealed that the general direction of China's fuel cell vehicle development in the future is: in the fuel cell bus, focus on the development of a new generation of fuel cells + wheel drive + high-power battery car; in the car, actively promote fuel cell mixing The mass production process of the power car.
According to public information, among the various types of fuel cells, hydrogen fuel cells, which have been promoted for more than a decade, are regarded as inexhaustible energy sources, and are referred to by experts as "the best-developed fuel cells."
As early as the 1960s, hydrogen fuel cells have been successfully used in the aerospace industry, using hydrogen fuel cells to generate electricity, without burning, thus achieving zero pollution and zero emissions.
It is reported that once hydrogenated, fuel cell vehicles can run more than 700 kilometers, five times that of battery-powered electric vehicles, and the maximum speed can be 140~150km/h. Compared with traditional cars, the energy conversion efficiency is as high as 60~80%, which is 2~3 times that of internal combustion engines. Moreover, hydrogen fuel cell vehicles have many advantages, such as low noise, only a few minutes of filling, and the battery device can be large or small, and the fuel hydrogen source is widely available and renewable.
Mao Zongqiang, a professor and doctoral tutor at Tsinghua University, said that hydrogen fuel cell vehicles can better meet people's daily needs than pure electric vehicles need to be charged for a long time and can only maintain short-distance driving. From a technical point of view, hydrogen fuel cell vehicles have completely replaced the current gasoline vehicles in terms of inflatable speed, driving range and maximum speed, and become the "second chapter" of the automotive industry following the internal combustion engine.
Costs and technical problems need to be tackled. "At present, the popularity of hydrogen fuel cell vehicles faces two major problems." Mao Zongqiang said that the price is the first.
It is reported that the core components of hydrogen fuel cells are proton exchange membranes and platinum catalysts, which are very expensive materials. They can be used in aerospace technology without cost, but they are used in mass-produced cars. For the difficulty of the popularity of hydrogen fuel cells, the car leader, Toyota Motor Corporation, can only guarantee that even in 2015, the total fuel of hydrogen fuel cell vehicles will be around 50,000 US dollars (equivalent to more than 300,000 yuan). According to the reporter's current market price, a hydrogen fuel cell vehicle costs about 1.5 million to 2 million yuan, which is much higher than the cost of a conventional electric vehicle with an internal combustion vehicle and a lithium battery.
In this regard, this has also become the reason why Volkswagen is not optimistic about the fuel cell vehicles in addition to the international market outside of Japan. Shigeru Shoji, president and CEO of Volkswagen Japan, has said that fuel cell vehicles are only likely to grow rapidly in Japan because the Japanese government subsidizes up to $28,500 per fuel cell vehicle, which far exceeds other country.
Faced with high cost is the bottleneck of hydrogen fuel cell vehicle development, Mao Zongqiang stressed: “Building a hydrogen refueling station is the key to the development of hydrogen fuel cell vehicles.†At present, the biggest obstacle to the application of hydrogen fuel cell vehicles in China is the lack of hydrogen refueling. station. It is reported that as of the end of 2013, the total number of global hydrogen refueling stations put into use has reached 208, and plans to build another 127. At present, there are only three hydrogen refueling stations in China, and the construction sites are in the first-tier cities of Beijing and Shanghai, and they are all demonstration projects. Compared with foreign hydrogen highways (a road with multiple hydrogen refueling stations), there is a far cry.
For example, in Japan, where hydrogen fuel cell vehicles are popular, the Japanese government plans to build 100 hydrogen refueling stations in four major urban circles by 2015, which is far higher than China's existing construction plans. In this regard, Zhuang Simao believes that one of the reasons for the existence of many restrictions on the development of fuel cell vehicles is that “the re-injection of hydrogen fuel is difficult and the infrastructure cost is too high.â€
Insiders explained that the development of domestic hydrogen fuel cell vehicles, in addition to enhancing the performance of the car, the source and storage of fuel hydrogen is also a headache. Hydrogen fuel cells require fuel hydrogen, which is costly and has no industrial chain support in China. In addition, fuel hydrogen has difficulties in many technical fields such as manufacturing, transportation, storage, and filling. In addition, hydrogen is a flammable and explosive gas. Especially after compression, the environmental requirements are extremely strict, so that it can last for a long time. Safely used in cars, and frequent refueling actions, the existing hydrogen storage technology requirements in the country are too demanding, and it is likely to rely heavily on government subsidies before the price drops.
