Fluorescent, a key material in fuel cell technology of concern

"Dongyue" completed the production of fuel cell core material sulfonic acid resin ion membrane, an annual production device of 500 tons has been completed and put into operation, solving the major bottleneck of hydrogen fuel cell production, China has thus become the second country in the world to possess this technology and industrialization ability. country.

The raw material of the Ionic membrane is fluorite. The main component of fluorite is calcium fluoride, which is an non-renewable strategic resource and is the source of the development of fluorinated chemicals. The global fluorite reserves are about 600 million tons, and China's reserves account for 54 %, ranking first in the world. China's fluorite resources are concentrated in the Ordos region of Inner Mongolia, where Yili Technology(600277) has abundant fluorite resources. Since the ion membrane electrolysis has the characteristics of environmental protection and energy conservation, adopting ion membrane electrolysis is the most advanced caustic soda production technology in the world. The ion membrane electrolyzer and the ion membrane are the core devices of the chlor-alkali device, and the key role is the perfluoro-sulfonate carboxylate membrane(PFC membrane) installed on the electrolyzer.

In order to implement the scientific concept of development, Yili Resources Group has constructed a development strategy of "fully building an international leading level of energy and chemical industry leading industry with PVC as the main line", and in accordance with the spirit of "developing a circular economy and building ecological civilization" proposed by the Party Central Committee. According to the pattern of integrated circular economic industries in the park, Yili Resources Group has built a "eight major projects" with an investment of 60 billion yuan, that is, 50 million tons/year coal mining, 1 million KW Shenhua Yili coal gangue power generation, 1 million tons/year PVC, and 1 million tons/year ion membrane burning soda plant. 500,000 tons/year PVC deep processing, 1 million tonnes/year high-end coal-based multi-generation, 500 MW / year solar photovoltaic cell, 1 million tonnes/year industrial slag cement(Yili Jidong Cement Factory).

Since 2003, with Yili Resources Group as the main investment line, it has attracted domestic industry giants. In accordance with the development model of the circular industry chain, it has jointly established 400,000 tons/year PVC with Shanghai Huayi Group and supporting 400,000 tons/year. Billion tons of chemical ion membrane caustic soda.
