Secondly, through active cooling and temperature feedback control strategies, the thermal effects of fuel cells under high loads and dynamic operating conditions were effectively addressed, reducing energy losses in the system. The combined results of various studies indicate that the integrated application of membrane electrode modification and intelligent thermal management significantly improves the energy conversion efficiency of hydrogen fuel cell vehicles, reduces energy consumption, and simplifies system temperature control. Finally, this study also explores the cost and engineering feasibility, and proposes the future development direction of hydrogen fuel cell vehicles in commercialization and practical applications. Through the optimization strategy of this study, the energy efficiency improvement of hydrogen fuel cell vehicles has important theoretical significance and application value.
