With the advancement of global energy transition hydrogen fuel cell vehicles are receiving more and more attention as a kind of transportation with good environmental performance. The energy conversion efficiency of hydrogen fuel cell system is a key factor in determining its economy and wide application. This study aims to improve the overall energy conversion efficiency of hydrogen fuel cell vehicles through the combination of membrane electrode modification and intelligent thermal management strategies. First, for the structural optimization of the membrane electrode of the hydrogen fuel cell, nanocatalyst and carbon-based carrier modification techniques were used to improve the activity of the catalyst and the ionic conductivity of the membrane electrode, thus enhancing the energy output and stability of the electric stack. 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.
