On December 8, technical experts from Wuhan Lvdong Hydrogen Energy said that previously, over 99% of the components needed in China had to be imported; “A 1-square-meter proton exchange membrane weighs more than 20 grams, and its price is comparable to that of gold of the same weight.” ” Today, the predicament has been overcome. Recently, China’s first fully self-controlled proton exchange membrane production line for hydrogen fuel cells was put into operation in Wuhan, with an expected annual production capacity of 300,000 square meters. The 300,000-square-meter proton exchange membrane production line that has been put into operation is capable of producing proton exchange membranes with thicknesses ranging from 8 microns to 20 microns. These products exhibit performance levels equivalent to or superior to those of similar domestic and international competitors in terms of proton conductivity, gas permeability, and mechanical strength, yet their price is only half that of similar foreign products.
As a core component of hydrogen fuel cells, the quality of the proton exchange membrane directly affects the service life of the cells. Industry experts explain that hydrogen undergoes a non-combustive redox reaction with oxygen; through a catalyst, electrons and ions are separated. Hydrogen ions can pass directly through the proton exchange membrane to reach the cathode, while electrons can only reach the cathode via an external circuit. When electrons flow to the cathode through this external circuit, direct current is generated. Currently, the proton exchange membranes used in hydrogen fuel cells are mostly synthesized from perfluorinated polymer materials. This material boasts advantages such as good stability and a long service life, but it is very difficult to develop and produce; the manufacturing costs are high, the price is expensive, the level of domestic production is low, and large-scale production with stable performance is even more challenging. Last July, **Dian Tou Hydrogen Energy Company established Wuhan Lvdong Hydrogen Energy Technology Co., Ltd. in the Wuhan Economic Development Zone, and began building the **Dian Tou Central China Hydrogen Energy Industry Base and R&D Center. The project involves an investment of 7 billion yuan, focusing on the research and development as well as production of core components for fuel cells, including proton exchange membranes, membrane electrodes, carbon paper, fuel cell stacks, and fuel cell systems. It also entails the research and development and production of key equipment for hydrogen production through water electrolysis. After 17 months of intensive efforts, the production line for proton exchange membrane in hydrogen fuel cells was finally put into operation.
