Recently, the Hunan Provincial New Materials Industry Association organized a "High Power Proton Exchange Membrane Fuel Cell Membrane Electrode and "Preparation Technology of Key Materials" project research results evaluation meeting. The evaluation committee is composed of authoritative experts and scholars in the industry. At the evaluation meeting, the main members of the project team reported in detail on behalf of the project team the characteristics and innovations of the preparation technology for high-power proton exchange membrane fuel cell membrane electrodes and their key materials. Experts from the evaluation committee listened to the technical research summary report, inspected the research site, and jointly discussed the technical details and application effects. After inquiry and discussion, the evaluation committee unanimously believed that the overall technical level of the project "Preparation Technology of Membrane Electrodes and Key Materials for High-Power Proton Exchange Membrane Fuel Cells" has reached the domestic advanced level, and some indicators are leading in the country. "Preparation Technology of Battery Membrane Electrodes and Key Materials" passed the evaluation of scientific and technological achievements, and it was recommended to increase further research investment and accelerate industrialization. Kuang Dezhi, the executive general manager of the project unit, told reporters that the engineering center is responsible for Corinth's research work in the field of hydrogen fuel cells. Combining the company's product technology characteristics, it gives priority to the engineering technology of the core key material "membrane electrode" As a key direction, we have carried out systematic and in-depth research on common problems that the industry has focused on for many years, and currently have many innovations in the preparation of membrane electrodes and catalysts. During the research process, the Engineering Center has successively built domestically advanced membrane electrode research clean laboratories and catalyst synthesis and testing laboratories, and imported advanced membrane electrode testing equipment, spraying equipment, pretreatment equipment, and catalyst testing equipment from the United States, Japan and other regions. etc., and established a scientific research team suitable for engineering research through introduction, training, etc., has applied for nearly 20 patents, and formulated internal testing standards for 9 performance indicators such as membrane electrode power density, life, and internal resistance9 item. Through continuous efforts, the Engineering Center has made breakthroughs in key fuel cell material experiments and product performance testing and evaluation capabilities, as well as the synthesis and preparation of membrane electrode samples and catalyst samples. At present, the experimental platform has relatively complete membrane electrode electrical performance testing and evaluation capabilities and catalyst key performance testing and evaluation capabilities. In terms of synthesis and preparation capabilities, the membrane electrode laboratory can prepare membrane electrode samples with power densities reaching the most advanced domestic level. And in 2018, laboratory samples have passed the test of a domestic drone customer on a fuel cell stack for drones; catalyst samples that are equivalent to the current most successful international commercial catalysts are available in the catalyst laboratory; for domestic products that have been In terms of membrane electrode engineering, a difficult technology that has existed for a long time, the demonstration of the engineering technical route has been completed, and the key preparation technologies in this technical route have been verified through online measurements at a famous Japanese membrane electrode engineering equipment supplier. , has broken through the slurry preparation issue suitable for engineering equipment. In the future, the Engineering Center will actively listen to the expert suggestions of the evaluation committee, continue to increase investment based on this result, establish a pilot platform for continuous preparation of membrane electrodes, study catalyst batch preparation technology and equipment, and establish and improve a comprehensive fuel cell system. and membrane electrode testing platforms, etc., continue to promote the technological progress and industrialization development of China’s independent hydrogen fuel cells.
