The 300000 square meter proton exchange membrane production line of Guodian hydrogen energy company recently announced that it was put into operation, which is China’s first fully autonomous and controllable production line, breaking the long-term monopoly of China’s proton exchange membrane Market by foreign manufacturers. Insiders pointed out that proton exchange membrane is widely used downstream, mainly in chlor alkali industry, fuel cells, electrolytic water hydrogen production and all vanadium flow battery energy storage system. Although foreign products account for more than 90%, some Chinese enterprises have achieved technological breakthrough and mass production, and the domestic alternative market space is broad and unstoppable. According to the research and calculation of Citic Securities Company Limited(600030) , the demand for proton exchange membrane is expected to be about 26.4 million square meters in 2030, and the market space can reach 13.2 billion yuan.
proton exchange membrane directly affects the cost and performance of fuel cell
It is understood that proton exchange membrane is the key material of membrane electrode in hydrogen fuel cell (fuel cell stack membrane electrode is composed of proton exchange membrane, catalytic layer and gas diffusion layer), which directly affects the performance, service life and cost of fuel cell. Foreign membrane electrode suppliers and Toyota, Honda and other passenger car enterprises have equipped with membrane electrode batch automatic production lines, with single line annual production capacity ranging from thousands of square meters to 10000 square meters. Due to many defects in the design and manufacture of domestic membrane electrodes, the technical parameters such as power density, durability and platinum load of precious metal need to be further improved, and most of the key component materials used still rely on imports.
From the value distribution of hydrogen energy industry chain, the position of proton exchange membrane is also prominent. As the heart of hydrogen vehicle, fuel cell system accounts for more than 60% of the cost of hydrogen vehicle, while the cost of electric stack also accounts for more than 60% of the cost of battery system. The study of Guosen Securities Co.Ltd(002736) further shows that in terms of stack composition cost, proton exchange membrane cost accounts for 16%, gas diffusion layer cost accounts for 12%, bipolar plate cost accounts for 23% and catalyst cost accounts for 36%.
From the actual installed capacity of fuel cells in various technical routes around the world, the proportion of installed capacity of proton exchange membrane fuel cells has remained at about 75% in recent years, which is the fuel cell technical route with the highest technical maturity and the highest proportion of installed capacity.
Up to now, China’s hydrogen fuel cells are in the commercial introduction period. According to China’s energy saving and new energy vehicle technology roadmap, the development goals of fuel cell vehicles in 2020, 2025 and 2030 are 10000, 100000 and 1 million. Citic Securities Company Limited(600030) the research report points out that with the accelerated promotion of hydrogen fuel cell vehicles, the demand for proton exchange membrane is expected to be about 26.4 million square meters, and the market space can reach 13.2 billion yuan. The installed capacity of proton exchange membrane electrolyzer starts and stops quickly and is well suited to renewable energy power generation. It is estimated that the installed capacity of proton exchange membrane electrolyzer will be about 20-25gw in 2030, the required consumption of proton exchange membrane will be about 950000-1700000 m2, and the market space can reach 480-850 million yuan.
large scale business is advancing steadily
A relevant person of Guodian hydrogen energy company told the financial associated press that the annual output of the 300000 square meter proton exchange membrane production line of Guodian hydrogen energy company can be equipped with 20000 hydrogen fuel cell vehicles. The production line can produce proton exchange membranes with a thickness from 8 microns to 20 microns. Compared with similar competitive products at home and abroad, the proton exchange membranes produced have better proton conductivity, gas permeability (H2) The mechanical strength is equivalent to or superior to similar foreign competitive products. It has been applied in high-power fuel cell stack and has received purchase orders from many companies.
The relevant person in charge of Wuhan green power hydrogen energy said that based on the hydrogen energy industry layout of the state power investment group, the company will carry out independent R & D and production of hydrogen fuel cell proton exchange membrane and other core components, as well as mass production of stacks and systems in Wuhan Economic Development Zone. The current project construction of the company is mainly carried out around the proton exchange membrane production line. It is planned to build phase I project from 2020 to 2023. Phase I project plans to build a proton exchange membrane R & D platform, mass produce 100000 square meters of proton exchange membrane pilot test line, and produce 10000 sets of fuel cell stack production lines and 5000 sets of fuel cell system production lines per year.
Previously, people from Dongyue hydrogen energy company introduced to the outside world that more than ten companies engaged in proton membrane research in the world are mainly American Kemu, Dow, 3M, Gore, Belgium Solvay, Japan Asahi Glass and Asahi Huacheng, as well as Dongyue hydrogen energy and Pan Asian Microvent Tech (Jiangsu) Corporation(688386) in China. Among them, Gore company of the United States has intellectual property advantages in reinforcing films. At present, the Nafion series films of Gore company are the most widely used, accounting for more than 90% of the global market, with an annual shipment of hundreds of thousands of square meters.
It is understood that Dongyue hydrogen energy, as the proton exchange membrane industrialization company of Dongyue Group, has carried out relevant research for 18 years. The company has a complete perfluorinated sulfonic acid resin industry chain. It is the enterprise with the largest share in the Chinese market after Gore and Kemu. At present, it has realized mass production and mass supply, and has large-scale supply capacity, At present, the phase I project of 1.5 million square meters proton exchange membrane production line is put into operation.
Guolian Securities Co.Ltd(601456) the research report points out that the localization degree of hydrogen fuel cell will be 60-70% in 2020, and the core components such as electric stack, membrane electrode, air compressor and hydrogen circulation pump can be controlled independently, while the core materials such as gas diffusion layer, catalytic layer and proton exchange membrane are also accelerating the research and development, which is generally in the stage of sample delivery test and verification. As it is expected that it will take 2-3 years for products from sample delivery test to mass production, it is expected that the hydrogen fuel cell industry chain is expected to fully realize domestic supply in the next 2-3 years.
Capacity sorting of proton exchange membrane related companies in China:
Hongji Chuang Neng: the company has built an independent membrane electrode production line with the largest production capacity in China, with an annual production capacity of 300000 square meters. At present, the yield of CCM has reached 99.9%, and the membrane electrode has also reached 99%.
