With the advancement of global energy conservation and emission reduction, hydrogen energy as a clean and efficient energy source has entered the public eye and spawned a new market for hydrogen fuel cells.
In particular, hydrogen fuel vehicles are of great significance to the realization of China's "double carbon" goal. According to the development plan of many provinces, by 2025, the number of fuel cell vehicles in China will be more than 120,000, showing a trend of rapid development.
99% of our country was once dependent on imports
Today, China has become the world's largest hydrogen producer. However, China is subject to people in the core component of hydrogen fuel cells - proton exchange membranes.
Proton exchange membrane fuel cells occupy a dominant position in the category of fuel cells, and the proportion of installed capacity has remained at about 75% for many years, and it is widely used.
If the hydrogen fuel cell is compared to a computer, the proton exchange membrane is the CPU of the computer, which is directly related to the three key indicators of the life, performance and cost of the fuel cell, and its importance goes without saying.
But it is also in such a critical field of proton exchange membranes that China's dependence on imports once reached 99%.
China started late in the proton exchange membrane track, and DuPont entered the track as early as 1969. This makes China open up a big gap with foreign giants from the beginning.
Moreover, due to the high technical threshold and complex production process of proton exchange membranes, it is very difficult for China to catch up with foreign countries.
The reason why proton exchange membranes are difficult to manufacture is because its main synthetic perfluorinated polymer material has certain defects, which makes it more difficult to develop and produce this material, and also makes proton exchange membranes very expensive.
Affected by the above factors, China's proton exchange membrane market is subject to the human situation is very severe.
In the global market, the proton exchange membrane market is controlled by enterprises in a few countries such as Japan, the United States, and Canada. Japanese Asahi Kasei, Asahi Whistle Glass, The United States Chemours, 3M, DuPont and other enterprises are the industry leaders in the proton exchange membrane market.
Chinese companies are completely gone.
Central enterprises have achieved breakthroughs
Such a situation has stung the hearts of many Chinese people. With the advancement of energy conservation and environmental protection, the status of hydrogen fuel cells is becoming more and more important, which also requires that China must achieve independent control in its core components.
As a result, the domestic proton exchange membrane began to break through. In this breakout battle, the State Power Investment Hydrogen Energy Company, as a central enterprise, plays a key role.
A few days ago, China's first fully self-service controllable production line - the State Power Investment Hydrogen Energy Company's 300,000 square meters, can produce 8 microns to 20 microns proton exchange membrane production line was officially put into operation.
It is understood that the production capacity of the production line after reaching production is enough to meet the needs of 20,000 hydrogen fuel cell vehicles, which has injected a huge impetus into the development of China's hydrogen fuel cell vehicle industry.
It is worth noting that the proton exchange membrane products of the State Power Investment Hydrogen Energy Company are not exported to similar foreign products in terms of proton conductivity and gas permeability, which proves that China has achieved leapfrog progress in the field of proton exchange membranes.
More importantly, the price of domestic proton exchange membranes is nearly 50% cheaper than that of foreign competitors.
According to experts: "1 square meter of proton exchange membrane weighs more than 20 grams, and the price is comparable to the same weight of gold." "This makes the cost of hydrogen fuel cells high. Today, with the advent of domestic proton exchange membranes, China's hydrogen fuel cell vehicles will be more competitive in terms of performance and price.
The production of the proton exchange membrane production line of the State Power Investment Hydrogen Energy Company plays a very important role in China's fuel cell industry, and even the heavy responsibility of energy conservation and emission reduction, which is very eye-catching. And for this moment, researchers at the State Power Investment Hydrogen Energy Company have been working hard for 17 months.
Not only the State Power Investment Hydrogen Energy Company, but also Wuhan Green Kinetic Hydrogen Energy and Dongyue Hydrogen Energy Company have also achieved major breakthroughs in the field of proton exchange membranes. Among them, the former will carry out the mass production of a variety of core components of fuel cells on the basis of the production line of the State Power Investment Hydrogen Energy Company; the latter has not only built a complete perfluorosulfonic acid resin industry chain, but also realized the production of 1.5 million square meters of proton exchange membrane production line.
Write at the end
From the performance of the above enterprises, it is not difficult to see that Chinese enterprises are accelerating their breakthrough in the field of proton exchange membranes, and China is getting rid of the dilemma of being subject to people in this field little by little.
And not only the proton exchange membrane, in the gas diffusion layer, catalytic layer and other core components that used to rely on imports, China is also rapidly achieving a breakthrough. Among the other core components of fuel cells such as stacks and membrane electrodes, China has achieved independent control.
According to the current situation, it is expected that in only 2-3 years, China's hydrogen fuel cell industry chain is expected to fully achieve localization supply. At that time, this crucial area will be fully in our own hands.
This will be conducive to the stable and safe development of China's hydrogen fuel cell field, so as to achieve more breakthroughs. I hope that our country can bring more good news in this area.
