my country develops hydrogen fuel cell vehicle technology -Lithium - Ion Battery Equipment
Data shows that by the end of 2017, the number of commercial orders for hydrogen fuel cell vehicles in my country has exceeded 1,000, and there are more than 200 hydrogen fuel cell vehicles used for demonstration operations. However, at the 2018 China International Hydrogen Energy and Fuel Cell and Hydrogen Refueling Station Equipment Exhibition held recently, the problem of the lack of core technologies for key components of fuel cells in my country was put on the table again. Some experts believe that the key zero of hydrogen fuel cell vehicles Components should be fully localized as soon as possible to reduce dependence on imports.(Lithium - Ion Battery Equipment)
In this regard, Zhang Jinhua, executive vice chairman and secretary general of the Chinese Society of Automotive Engineering, said in an interview with a reporter from China Automotive News that my country does have a certain gap with foreign countries in terms of key core component technologies, but such a gap is not insurmountable. With the gradual improvement and maturity of my country's hydrogen fuel cell vehicle industry, it will definitely drive the improvement of the localization capability and strength of related components. In the next 5 to 8 years, the overall competitiveness of China's hydrogen fuel cell vehicles will increase. It is expected to reach the international advanced level.
Lack of core technology leads to high costs
Although the development of hydrogen fuel cell vehicles in China started early, from the current market performance, there is still a certain gap compared with Japan, South Korea and the United States. According to statistics, from 2013 to the end of 2017, a total of 6,475 hydrogen fuel cell passenger vehicles were sold worldwide, of which Toyota accounted for more than 75% of sales. Among the many factors that hinder the further large-scale popularization of hydrogen fuel cell vehicles in my country, the lack of mastery of the core technology of key components is considered to be an important reason for the high cost of products.
Xie Jinshui, chief engineer of Wuhan Himalaya Optoelectronics Co., Ltd., proposed that at present, most of the hydrogen fuel cell vehicles installed in my country use foreign stacks and technologies, and the proportion is estimated to reach more than 70%. A set of data given by Wang Cheng, director of the Hydrogen Fuel Cell Laboratory of Tsinghua University, also confirms this fact: "Most of the catalysts for these more than 1,000 vehicles are imported, and almost all membrane electrodes are imported. The development of hydrogen fuel cell vehicles must be The technology cannot be hollowed out, and the industry must be solidified. Imports lead to high costs, and the cost of hydrogen fuel cell vehicles cannot be reduced, so the industrial scale cannot be achieved.”
It is reported that the fuel cell system is the core of hydrogen fuel cell vehicles, accounting for 52.9% of the cost, followed by high-pressure hydrogen storage tanks (33.7% of the cost) and batteries (5.8% of the cost). At present, the fuel cell system and hydrogen storage tank technology are in the hands of European, American and Japanese manufacturers, and my country is carrying out research and development of related technologies.
In the past, platinum was an indispensable part of the stack as a catalyst, and it used to be a key factor restricting cost reduction, but at present, the platinum loading of Honda stacks has been as low as 0.12g/kg, and the platinum loading is still in the process of continuous decline. Taking Honda Clarity as an example, the platinum consumption of a single fuel cell vehicle catalyst has dropped to about 10g, while a single diesel vehicle needs 5g platinum as an exhaust gas purification catalyst. At present, the platinum consumption of fuel cell catalysts has been reduced to the industrialized level, and it is continuing to decline. will not cause a shortage of platinum demand. "my country's use of platinum is still larger than that of foreign countries." Zhang Jinhua pointed out that this has led to a further increase in the cost of domestic products.
Introduction and absorption is the only way for industrial development
While clearly aware of the gap between my country's hydrogen fuel cell vehicles and foreign advanced levels, Zhang Jinhua believes that this gap is not an insurmountable gap, as long as there is market traction, industrial coordination and the support of relevant government departments, my country's hydrogen fuel cell vehicles Development prospects are limitless.
