The hydrogen fuel cell vehicles and in-depth analysis of the development of abroad
"Made in China 2025" puts forward "energy conservation and new energy vehicles," as a key development areas, has been clear about the "continue to support the development of electric vehicles, fuel cell cars, master automobile low carbonization, informationization, intelligent core technology, promote their own brands and energy saving and new energy vehicles and the international advanced level" development strategy, for energy saving and new energy automobile industry development in our country, pointed out the direction. Including the content of the planning for fuel cell vehicles to make the following.
1, the key materials, spare parts localization step by step. By 2020, fuel cells key material mass production quality control and assurance ability; By 2025, achieving high quality key materials, spare parts localization and batch supply.
2, fuel cell stack, and gradually improve the vehicle performance. By 2020, the fuel cell stack life 5000 hours, the power density of more than 2.5 kw/l, the vehicle durability reached 150000 kilometers, the limited driving distance of 500 km, hydrogenation time for 3 minutes, cold start temperature below 30 ℃; By 2025, the fuel cell stack system reliability and economy increase, compared with the traditional cars, electric cars, has certain market competitiveness, realize batch production and market promotion.
3, fuel cell cars run further expansion. 2020 to 2020, the production of fuel cell car and to run the demonstration; By 2025, hydrogen production, hydrogenation and other supporting infrastructure improvement, basic fuel cell vehicles to realize regional small operation.
Electric cars, there is no doubt that is the main force of the growth of new energy vehicles this year, also is the darling of the national policy, fuel cell vehicles is unknown.
The development of hydrogen fuel cell is internationally recognized as the ultimate new energy vehicles, completely zero pollution, zero emissions. Electric car hot will have influence on the development of fuel cell vehicles. So, the industry for "made in China 2025" planning in the fuel cell car is able to perform a skeptical attitude. By comparing the development of hydrogen fuel cell vehicles abroad, we can know the differences.
New energy automotive engineering center of tongji university professor cun-man zhang said that China is more attention to the development of hydrogen fuel cell vehicles, a few years ago we reviewed the obvious, in recent years some stagnation. Cun-man zhang, says professor hydrogen fuel cars and technology of China behind the developed countries of 5 to 10 years, the gap in five years we still have a chance to pursue, if more than 10 years, we catch up will be very hard ".
Hydrogen fuel cell car development phase analysis
Professor cun-man zhang said that the development of hydrogen fuel cell vehicles through several periods.
Gm in 1966 began to develop hydrogen fuel cell vehicles, Honda began in 1992, Toyota started in 1996, began in 1998.
2002-2008 years, is still belong to the experimental research stage, there is no formal operational use; 2008-2015, belongs to the product and the combination of social stage, began to be put into use. In 2008, Honda FCX Clarity first hydrogen energy vehicles used for rental business, Toyota Mirai fuel-cell cars by 2014. South Korean modern mass production in 2013 Tucson FCEV fuel-cell cars.
In 2015-2020, hydrogen energy vehicles entered the stage of popularization. Cun-man zhang, said professor in 2015 is the first year of hydrogen fuel cell vehicles. According to the plan, the sales of a new generation of Honda 2016 Clarity hydrogen fuel cell vehicles, Daimler will also be 2017 formally sales of hydrogen energy vehicles. According to introducing, Daimler had been expected in 2014-2015 with hydrogen fuel cell vehicles, but in order to further reduce the cost, began last year with nissan, ford, cooperation development of hydrogen fuel system.
2020-2025, popularize the expansion phase, the rapid development of the hydrogen energy vehicles to 2025 began to commercialization.
2, the domestic
In 2001, China began to hydrogen fuel cell car research and development, started relatively late abroad.
2001-2008, belongs to the technology research and development stage, also did not have the capacity to produce hydrogen energy vehicles. Until the 2008 Olympic Games in Beijing the hydrogen fuel cells were, the only cause for concern.
2008-2020, technology and society stage, in 2010, the hydrogen fuel cell vehicles as were once again appear in the Shanghai world expo. In 2014, saic launched "innovation adventure - 2014 new energy vehicles wan lixing" activities, the roewe 750 fuel cell vehicles, with its powerful and manipulation of the characteristics of stable performance, become the domestic hydrogen fuel cell car technology.

2020-2025, starting in 2020, is expected to domestic hydrogen fuel cell vehicles began to spread, to the popularization of 2025 is bigger stage. Many enterprises have also begun to hydrogen energy vehicles project layout, in preparation for the ultimate goal of new energy.
In 2030, began to commercialization stage.
Cun-man zhang, said professor in China since 2001, China began to pay attention to the research of hydrogen fuel cells, from infancy into the commercialization stage, the whole, the hydrogen energy automotive technology to lag behind the foreign 5-10 years. At present, the battery electric vehicles as the main development direction, a lot of material, manpower, financial resources into, as for the development of hydrogen energy situation is not optimistic. And there is no national policy leading role, so the development of hydrogen energy vehicles will have certain hysteresis.
The development direction of Chinese car companies have great influences on the government, independent research and development of free and flexible, leading role is not obvious. Professor cun-man zhang pointed out that compared with abroad, regardless of the Asian countries such as Japan, South Korea, the United States, Germany and other European and American countries of car enterprise independent research and development of the dominant role, proactive, flexible market freedom degree is high. "In the future the development of hydrogen fuel cars at home and abroad the gap is unlikely, worrying or gap widens, mainly the domestic independent brand is continuing to pour money into power."
The comparison between the present situation of hydrogen fuel cell vehicles at home and abroad
The gap of automobile industry, the accumulation of technology is one of the important factors. From the perspective of the development of traditional automobile, China's technology accumulation of a relatively short time, behind the one hundred - year - old car power.
Through the following several aspects of comparative analysis, it can be seen that the hydrogen fuel cell car technology in China and abroad.
1, the cost. Abroad has taken the hydrogen fuel cell car cost control in 30-400000 yuan, compared with the early stage, the cost has been reduced by half. The future there will be a new breakthrough.
2, range. Have been able to reach 500-500 km, compared with electric cars, there will be no "range anxiety".
3, charging time. Hydrogen fuel filling time can be controlled in 3-5 minutes. Range and filling time is fully capable of equivalent to that of traditional fuel vehicle, but more obvious environmental benefits.
4, low temperature resistance and high temperature performance. Can in - 35 ℃ ~ 45 ℃ temperature interval operation, low temperature and high temperature resistance. This compared with electric cars advantage is more outstanding, the temperature too high or too low all affect the operation of electric vehicles.
5, life can be up to 10 years, or 200000 kilometers.
By the knowable, hydrogen fuel cell vehicles abroad has achieved 500-700 km range, level has more than 2025 "made in China" in 500 kilometers of the goals and objectives. "Abroad at present, the development level of hydrogen fuel cell vehicles is the development of China in 2025 to achieve goals. In the research and development of hydrogen fuel cell vehicles in China's your move."
The current bottleneck of hydrogen fuel cell vehicles in China, as well as the future development goals
The hydrogen fuel cell car is currently in the following several aspects of problems remain to be solved urgently:
1, the fuel cell stack technology: poor reliability, features low density, high cost;
2, high pressure hydrogen storage system: the manufacture of high pressure hydrogen storage cylinder and valve;
3, battery components: proton membrane, catalyst, carbon paper and double plate industry chain is not perfect;
4, cell auxiliary system components: wind, the lack of hydrogen circulating pump;
5, engine system integration and control: stable reliability;
6, to form a system: the under-funded.
Fuel cell vehicles is the use of hydrogen and oxygen in the air under the effect of catalyst, the electrochemical reaction in the fuel cell to produce electricity as the main source of power.
As prof cun-man zhang said, at present our country and abroad in terms of the development of hydrogen fuel cell vehicles there is obvious difference. In order to shorten the gap, "2025" made in China to determine the hydrogen fuel cell car technology development goals and direction.
