2.SAIC: The company will realize the total revenue of 742 1 billion in 2020. Holding 34. 19% equity of Xinyuan Electric Power, Xinyuan Electric Power is the first enterprise in China devoted to the industrialization of fuel cells, and has realized the production of key materials of fuel cells such as proton exchange membranes and stack components. 3. Shanghai Electric: The 2020 annual report shows that the company's operating income is 65.438+0373 billion yuan, up 7.67% year-on-year, and the compound growth rate in recent three years is 654.38+06.48%. Shanghai Electric began to study proton exchange membrane fuel cell technology from 20 16. After three years of independent research and development, fuel cell engine system, stack and membrane electrode technology and products have been successfully developed.
4. Great Wall Electric Appliances: The operating income in 2020 was 2.065 billion, up by 7.68% year-on-year. The company invested 654.38+005 million yuan to jointly establish Dalian Xinyuan Electric Power Co., Ltd. with Dalian Chemical Industry of Chinese Academy of Sciences (accounting for 265.438+0%) to engage in the research and development and production of proton exchange membrane fuel cells. Relying on the proton exchange membrane fuel cell technology owned by Dalian Institute of Chemistry, Chinese Academy of Sciences, with the development of mass production technology and various fuel cell products, the company will commercialize and industrialize it as soon as possible.
5. Tongji Science and Technology: The 2020 annual report shows that the company's operating income is 6.303 billion yuan, a year-on-year increase of -0.76%, and a compound growth of 38.54% in the past three years. Tongji Technology and Shanghai Li Shen * * * set up a subsidiary, Zhongke Tongli, to study proton exchange membrane, because this part of technology is the most difficult to break through.

In China, proton exchange membranes have been made since 1950s, and perfluoroproton exchange membranes have been made since 1980s, but the progress is slow. In 2003, with the support of the Ministry of Science and Technology, a systematic research work was carried out. 20 17 China perfluorinated proton exchange membrane has reached the world-class level, and Dongyue is the representative enterprise.
From 2003 to 20 19, Dongyue started the project of one million square meters of perfluoroproton exchange membrane, and each step paid a lot of money and gained a lot of experience and lessons. So far, only Dongyue has the conditions for mass production in China, mainly because:
First of all, we must have an industrialized and stable production platform. Fluoride materials are very special, corrosive and explosive. Secondly, there must be a polymer platform, and there must be experimental evaluation in combination with automobile companies. No one dares to use it without experimental evaluation. At present, only Dongyue has a perfect chain; Furthermore, there must be a strong talent team to support it. It is also very important that Dongyue has invested heavily in the proton exchange membrane plate, and the huge continuous investment is beyond the reach of ordinary companies.
