With fuel power cell as the power source of automobile, the chemical reaction process of fuel power cell will not appear harmful products, so fuel power cell vehicle is pollution-free vehicle, the energy conversion efficiency of fuel power cell is 2 ~ 3 times higher than that of internal combustion engine, so from the aspect of energy utilization and environmental protection, fuel power cell vehicle is an ideal vehicle. A single fuel power cell must be combined into a fuel power cell stack, which can get the power of sniffing again and meet the requirements of vehicle use. In recent years, fuel power cell technology has made great progress.
Fuel power cell has the advantages of zero emission, high efficiency and high energy density. If the advantages of hydrogen fuel power cell and the existing power battery are combined, it can make up for the shortcomings of electric vehicles and achieve real zero emission. Recently, Wan Gang, Minister of the Ministry of science and technology of the people’s Republic of China, made it clear at the forum of China’s 100 people’s meeting of electric vehicles in 2017 that fuel power cells have development advantages in the development of pure electric vehicles with power batteries in China, so we should take this opportunity to promote the development of new energy vehicles.
Not long ago, Japanese automaker Honda and U.S. General Motors jointly announced that they will cooperate to produce a new generation of hydrogen fuel cell vehicle system to maintain their competitive advantage in the field of environmental protection vehicles.
It is obviously not a simple coincidence that both automobile manufacturers and government officials have issued a signal that fuel power cells will be the breakthrough point of new energy vehicles in the future.
So, can fuel power cells lead the future development of new energy vehicles? In 2017, fuel power cell is on the cusp of new energy vehicle development.
Battery problem hinders the market development of new energy vehicles
Today, are you willing to buy a new energy vehicle as a travel tool? To deal with this problem, many consumers have made the choice difficult.
The purchase of new energy vehicles means that they must adapt to the current environment and the far from perfect performance of the vehicle itself; it is indeed a temptation not to buy new energy vehicles, which enjoy higher state and local subsidies at this stage.
In fact, this idea is not difficult to understand. Since the first year of the development of new energy vehicles, mileage anxiety has been bothering people. This is directly related to the performance of the battery.
At present, the lithium-ion batteries widely used in the field of new energy vehicles include lithium iron phosphate batteries, lithium manganate batteries, ternary lithium-ion batteries and lithium titanate batteries. It should be said that lithium-ion batteries support the development of new energy vehicle industry in China at the present stage.
Although these batteries have many advantages, many consumers are not satisfied with their long charging time and general charging safety. Miao Wei, Minister of the Ministry of industry and information technology, once said publicly that although the production and sales of new energy vehicles in China ranked first in the world for two years, they are still in the primary stage, and some problems need to be solved.
Among them, the battery is one of the pain points to be solved.
As we all know, among the batteries that can be produced on a large scale, lithium-ion battery is more mature than lead-acid battery technology, and has become the target pursued by major automobile enterprises. But the lithium-ion battery itself does not have energy. Now the lithium in the lithium-ion battery can not generate electricity, it just stores electric energy. When it is used, it will discharge. When the power is exhausted, it can only be recharged. So lithium ion battery itself depends on external power supply.
In this way, the battery should be continuously supplied with energy to ensure normal use. However, charging is easy to say, but it’s hard to accept when it’s really implemented. Five or six hours of regular charging often brings about 200 kilometers of driving range.
In addition, the performance of power lithium battery will decline with the increase of charging times. When the battery capacity declines to less than 80% of the rated capacity, the power lithium battery can no longer be used for driving electric vehicles, which means the service life of new energy vehicles will end. If the battery is eliminated directly, it will cause serious waste of resources and environmental pollution.
According to the prediction of China Automotive Technology Research Center, by 2020, China’s electric vehicle power lithium battery scrap will reach 120000-170000 tons. How to realize the recycling of these power lithium batteries is also an important topic.
At present, many international car companies, including Toyota, Hyundai, GM, Nissan and Mercedes Benz, are developing corresponding fuel cell vehicles.
According to the reporter, fuel power cell is hydrogen oxygen hybrid fuel cell. Compared with ordinary chemical cells, fuel power cells can supplement fuel, usually hydrogen. For China, hydrogen energy will play an important role in energy transformation and upgrading due to its low-carbon attribute, especially in the field of transportation. Now the United States, Japan and other important countries have turned such consensus into strategy, or even practice. It is hoped that all parties will work together to promote the development of hydrogen fuel cell vehicle technology and industry. Zhang Jinhua, executive vice president of China Automobile Industry Association, told China consumer news.
Fuel power cell has obvious application advantages
Automotive fuel power cell
Finally, I waited for you. Fortunately, I didn’t give up. After many years of market tests, new energy vehicles are waiting for a best partner, fuel power cells.
In recent years, with the rapid development of fuel cell vehicles, their high efficiency, energy saving and good environmental performance of zero emission or near zero emission make them rapidly become a hot spot in the field of energy and transportation in the world.
Wang Binggang, head of the supervision expert group for major electric vehicle projects of the Ministry of science and technology, said in an interview with China consumer daily that more and more automobile enterprises are now paying attention to the field of fuel power cells. Although it is difficult to commercialize in a large scale in a short time, the development direction is correct.
Fuel power cell is popular because of its superior performance.
First of all, the fuel power cell power generation device uses electrochemical power generation, which is first converted into thermal energy for combustion, and then into electric energy. At present, this device has been industrialized, greatly improving the fuel utilization. In other words, the same energy can drive farther, which is absolutely good news for the majority of new energy owners.
In addition, there is no noise in the process of fuel power generation, and the fuel power cell is essentially hydrogen and oxygen, water appears in the chemical reaction, which has outstanding environmental performance.
In addition to car technology, charging seems to be a problem. Traditional fuel vehicles can be refueled in three to five minutes, but new energy vehicles need much longer to charge.
As for this inconvenience, the advantages of fuel power cell are more obvious. The charging process can be completed by filling hydrogen or changing electrolyte. Hydrogen is the same as gasoline. As long as the purity is up to standard and the pressure is up to standard, there is no difference.
According to the reporter, in order to promote the development of fuel power cell vehicles, the State Council specially deployed the development of fuel power cell vehicles in the “energy saving and new energy vehicle industry development plan (2012-2020)”, planned to increase R & D and investment in key infrastructure components, fuel power cell system, infrastructure and demonstration, and proposed to conquer the vehicles in the next few years In addition, we have also made use of fuel power cell durability technology to promote the construction of hydrogenation station and the demonstration operation of fuel power cell vehicles.
In terms of the latest national subsidy policy, the central subsidy limit for pure electric buses is 300000 yuan, while the subsidy for large and medium-sized fuel cell buses is as high as 500000 yuan, and the subsidy amount for fuel cell buses does not decline. Therefore, it is a very good development opportunity period for fuel cell buses before 2020.
It can be predicted that the double positive factors of national planning and policy will undoubtedly play a positive role in promoting the development of fuel cell vehicles.
Independent brands need to work harder
In 2016, China’s new energy vehicles still maintained a rapid growth rate.
According to the data of China Automobile Industry Association, 507000 new energy vehicles were sold last year, up 53% over the same period last year. In the context of the hot market as a whole, the sales volume of major new energy vehicle companies with independent brands as an important force has also been further pushed to a new record.
However, the above achievements do not represent the embodiment of the overall hard power of independent brands.
The reporter learned that the national new energy saving and new energy vehicle technology roadmap has defined the technical route of fuel power cell system and vehicle development, which will gradually improve the system performance, prolong the service life, reduce the cost, and promote the development of fuel power cell vehicles.
Unfortunately, for the implementation of this technical route, the independent brand is obviously half a beat slower than the foreign car companies.
Facing the technology field that is expected to be the winner or loser of new energy vehicles, Toyota, Honda and Hyundai have early launched mass production versions of fuel power cell vehicles. International mainstream battery companies continue to pay attention to the research and development of fuel power cells, and a number of vehicle companies have launched mass production plans.
In contrast, the gap between China’s fuel cell vehicles and foreign products in terms of overall vehicle design, economy and driving range is not big, but the power of fuel cell engine and R & D investment of vehicle enterprises are significantly lower than foreign levels. For example, the fuel cell engine of SAIC is about 35-50kw, while that of foreign countries is about 90-100kw.
In fact, the fundamental reason is that the volume power density of fuel cell engine loaded in our country is lower than that of foreign advanced level. Generally speaking, there is no great progress in the field of fuel power cell passenger vehicles, only in the fuel power cell commercial vehicles, the first to achieve small batch production and commercial application. According to the reporter, Yutong Bus has begun to produce fuel cell buses, and two buses have entered the promotion catalogue of new energy vehicles. Technically, we basically have the conditions to develop hydrogen fuel cell vehicles. So whether we want to make fuel power cells in China or not, and whether there is such a foundation, the answer is yes. To make fuel power cells, we have a certain foundation, but there is a gap, and the gap between us and foreign countries is still very large. Professor Zhang Tong, director of new energy vehicle engineering center of Tongji University, concluded.
