　　Fuel cells are one of the rapidly emerging industries in the past year. Because they are environmentally friendly, pollution-free, noiseless, and highly efficient, they can be widely used in various power generation systems and vehicles. Hydrogen fuel cells (PEMFC) and new energy vehicles based on fuel cells are important development directions for my country's new energy vehicle industry. According to the "Blue Book on Infrastructure Development of China's Hydrogen Energy Industry", by 2020, China's fuel cell vehicles will reach 10,000, the number of hydrogenation stations will reach 100, and the total industry output value will reach 300 billion yuan; by 2030, the number of fuel cell vehicles will reach reached 2 million, the number of hydrogen refueling stations reached 1,000, and the industrial output value exceeded one trillion yuan. Among them, the fuel cell system is the core of the entire industrial chain, accounting for 50% of the total vehicle cost, and will become the largest segment in the hydrogen energy industry. Although the hydrogen fuel cell has a simple principle, its structure is very complex. The membrane electrode (MEA) is the core component of the hydrogen fuel cell and generally consists of a catalyst layer, a proton exchange membrane, and a gas diffusion layer. As an electrochemical reactor in a hydrogen fuel cell, in the MEA, hydrogen loses electrons and becomes protons. After passing through the membrane, it reacts with external circuit electrons and oxygen to form water and generate electricity. According to Dr. Xiaoan, the person in charge of Momentum Materials, there is currently a big gap between domestic MEA and foreign countries in terms of performance and lifespan. More than 80% of the demand relies on imports, and the price is as high as 1500-2500￥/kW. A 100kW electric vehicle uses imported MEA. The cost is as high as 200,000 yuan. The catalyst layer is the site of electrochemical reactions in hydrogen fuel cells and plays a key role in the performance of hydrogen fuel cells. At present, the traditional hydrogen fuel cell catalyst layer in the world is composed of a mixture of carbon black powder supported by platinum nanoparticles and polymer dielectric (such as Nafion?). This method has complicated processes, high cost, and poor controllability. The catalyst layer of the nanoporous carbon scaffold (NCS) film based on momentum materials surpasses the traditional carbon black-based catalyst layer in key indicators such as performance and lifespan. This is attributed to its continuous electronic conductors and 3D interconnected microscopic mass transfer channels. More importantly, the use of catalyst layers based on NCS membranes will greatly simplify the production process of hydrogen fuel cell membrane electrodes and achieve microscopic controllable distribution of core reaction materials such as catalysts, carbon scaffolds, and proton conductors, thereby achieving operable battery production. sex. According to Dr. Li Xiaoan, the use of porous carbon films can effectively improve battery performance and life. Experimental data shows that MEA can more than double its life by using porous carbon films. At present, there is no similar product of nanoporous carbon scaffold (NCS) film in China. After graduating from Nanjing University of Science and Technology with a master's degree in 2009, Dr. Li Xiaoan studied at the University of Calgary in Canada for eight years, focusing on proton exchange membrane fuel cell related technologies and new technologies. Nanostructured carbon materials. When I returned to China for market research in 2017, I discovered that there was a gap in related domestic industries. Therefore, I founded Nanjing Momentum Materials Technology Co., Ltd. in April 2018 to engage in the development, large-scale production and production of new nanopore structured carbon materials and their derivatives. Sale. Momentum Materials has received strong support from the Nanjing government since it settled in Lishui. It has received multiple talent plan grants and innovation and entrepreneurship competition awards, with a total of more than 2 million yuan in awards. It is a "black technology" project born out of Nanjing's long-term policy of encouraging innovation and entrepreneurship. . Momentum Materials Technology Co., Ltd. is not only responsible for the human resources of Xiaoan's refined technology, but also its operations and R&D teams are controlled by high-level talents. For example, R&D team members Ji Congmin and Zhang Ke respectively hold a master's degree in Chemistry from Tsinghua University and a Ph.D. from the University of Calgary. In addition, There are professors from Nanjing Institute of Technology, South China Institute of Technology and many other universities sitting on the advisory team. Nanoporous carbonized membranes are widely used. They can not only be used as membrane electrode materials, but also can be used in water treatment, supercapacitors, catalyst carriers and other fields. The main problem with nanoporous membranes at present is that they are still in the experimental stage, so the cost is relatively high. Expensive, but according to reports, the cost will drop significantly after mass production in the next stage. The company's current main source of income is the sale of nanoporous carbon to companies and universities, with revenue expected to exceed one million in 2019. Currently, Momentum Materials is seeking financing, which will be mainly used for technology incubation of large-scale mass production of NCS films and NCS-based MEA product development and market expansion.
