Abstract
As the global energy structure transitions and environmental protection demands become increasingly urgent, fuel cell vehicles (FCVs) have emerged as a critical direction for clean energy transportation, making the design and performance optimization of their power systems a research hotspot. This study aims to develop an efficient and reliable power system for FCVs and conduct a comprehensive evaluation of its performance. An integrated fuel cell power system design is proposed, incorporating key components such as the fuel cell stack, hydrogen storage system, auxiliary power source, and control system, while establishing a multi-ob jective optimization model to maximize system efficiency. By combining simulation analysis with real-vehicle testing, the designed power system was thoroughly investigated. The results indicate that under various operating conditions, the system demonstrates superior energy conversion efficiency and dynamic response characteristics, particularly achieving a 15% reduction in hydrogen consumption per 100 kilometers and a 20% improvement in acceleration performance under urban driving conditions compared to traditional solutions. Additionally, an innovative intelligent energy management strategy was introduced, optimizing the collaborative operation between the fuel cell and auxiliary power source, which significantly enhanced the overall energy efficiency and reliability of the system. This research not only provides theoretical foundations and technical support for the design of FCV power systems but also makes a positive contribution to the advancement of new energy vehicle technology.
