On the 5th, it was learned from Tianjin University that Professor Jiao Kui from the School of Mechanical Engineering led a team to propose a new digital design method for fuel cells through high-precision mathematical modeling. This method can optimize fuel cell design schemes, improve battery performance, shorten research and development cycles, and reduce costs. The relevant results were recently published in the international journal Energy and Environmental Science. Fuel cells are the fourth important power generation technology after hydroelectric power, thermal power, and atomic power, and are receiving increasing attention due to their clean, efficient, and pollution-free characteristics. Especially hydrogen fuel cells, with their zero pollution and high efficiency characteristics, have gradually been applied in public transportation, commercial vehicles, ships and other scenarios. However, due to cost constraints, the fuel cell related industry chain has not yet fully demonstrated its capabilities. Jiao Kui introduced that a reasonable fuel cell structure design should promote internal gas transmission, heat dissipation, and liquid water discharge, thereby improving battery performance. At present, relevant manufacturers lack efficient and high-precision simulation models and digital assisted design methods for commercial fuel cells, as well as innovative battery design solutions, which hinders the improvement of fuel cell power density and cost control. Studying the internal mechanism of fuel cells and optimizing their design is crucial for promoting their commercialization process Jiao Kui said. The team proposed a design method suitable for commercial fuel cells and established a three-dimensional and one-dimensional simulation model of large-sized fuel cells, which has a computational efficiency 10 to 20 times higher than traditional three-dimensional models. It can quickly propose multiple battery design schemes and shorten the research and development cycle. This design method can also optimize the distribution area structure of fuel cells, significantly improving their performance. Taking hydrogen fuel cells as an example, the fuel cells designed by Yihuatong using this new method can improve electrochemical reactions and flow resistance distribution consistency by more than 20% compared to mainstream products in the current market, while the manufacturer's design and manufacturing costs can be reduced to 60%, and the research and development cycle can be shortened by more than 30%, "said Dr. Li Feiqiang, co corresponding author of the paper and deputy general manager of Beijing Yihuatong Technology Co., Ltd. It is understood that the digital assisted design method proposed by Jiao Kui's team has universality and can also be extended to many other electrochemical device fields such as lithium batteries and electrolytic cells.
