Design of Hydrogen Fuel Cell Cooling Systems: An Integrated Study of Air and Liquid Cooling Technologies

As the application of hydrogen as a clean energy source increasingly expands into the automotive industry, Hydrogen Fuel Cell Vehicles (FCVs) have emerged as a pivotal technology for the green transformation of transportation, attributed to their zero emissions, high energy density, and rapid refueling capabilities. However, thermal management issues in hydrogen fuel cell systems significantly impact their performance and lifespan, especially under high-power operating conditions. This study addresses the limitations of existing air and liquid cooling technologies in high-power fuel cell systems by proposing an integrated cooling system design. Through theoretical analysis, structural design, and experimental testing, this paper examines the performance of the integrated cooling system under various operating conditions. The results demonstrate that the system effectively maintains the hydrogen fuel cell within the optimal operating temperature range, addressing the thermal management challenges of traditional cooling methods and enhancing the system's thermal efficiency. The findings provide crucial technical support for the application of hydrogen fuel cells in the automotive industry and lay a solid foundation for the development and application of efficient and economical fuel cell cooling technologies in the future.
