Perfluorosulfonic acid carboxylic acid ion membrane/Chlor-alkali ion membrane, or perfluorinated ion membrane, is the core technical material in exchange membrane fuel cell and chlor-alkali industry. But the chlor-alkali ion membrane used in the exchange membrane fuel cell and the chlor-alkali industry is not the same. Chlor-alkali ion membrane is a special cation selective permeation membrane, mainly used in chlor-alkali industry.
Before June 30, 2010, only a few companies in the world, such as DuPont of the United States and Asahi Kasei of Japan, possessed this technology, and they imposed technical blockades on other countries, forming a monopoly in the world and expensive.
After 8 years of scientific research, on June 30, 2010, SDDY Polymer Materials Technology Group successfully realized the commercial production of perfluorinated ion membranes. The last power-on of the 10,000-ton chlor-alkali unit was The monopoly of this technology. It marks that China has become the world’s third country with core technology and production capacity for chlor-alkali ion membranes. At the same time, China’s independently developed chlor-alkali ion membranes for exchange membrane fuel cells are also successfully mass-produced, making China the second country that can independently A country that develops and produces chlor-alkali ion membranes for exchange membrane fuel cells.
High performance fuel cell proton membrane
High-performance fuel cell proton membrane is the "core material" of fuel cell vehicles. Based on 10 years of technology accumulation, SDDY and the Mercedes-Benz Ford Joint Venture (AFCC) held a signing ceremony for the joint development of automotive fuel cell membranes on November 27, 2013, aiming to further improve the performance of SDDY fuel cell membranes through cooperation between the two parties. The technological level will accelerate the industrialization of clean new energy fuel cell vehicles in the world.
The fuel cell membrane produced by SDDY has been fully certified by Mercedes-Benz and Ford (AFCC) fuel cell membranes, with a life span of more than 6000 hours and world-leading performance. This is a brilliant achievement China has achieved in this high-tech field and not only supports China's fuel cell vehicles. The development of fuel cell vehicles is also of great significance to the mass production of global fuel cell vehicles. "
