“…In addition, studies for the cold start strategy optimization of the stack are mostly based on modeling and simulations, which cannot fully reflect the actual cold start situation due to assumptions and simplifications. 17 Therefore, in this paper, the cold start experiment was conducted using a stack comprising 20 cells with an area of 285 cm 2 . Moreover, a parameter sensitivity analysis was performed by considering the voltage inconsistency and cold start time during the cold start process.…”

The adaptability of fuel cell vehicles in low-temperature environments remains challenging for their commercialization owing to the propensity of water within the fuel cell to freeze during a cold start, which impedes gas transmission and subsequent reactions. Consequently, the initial water content before cold start and the heat and water generated during this process are crucial for achieving a successful cold start. In this study, current- and voltage-controlled starting strategies are analyzed using a stack comprising 20 cells with an area of 285 cm2. Furthermore, key parameters related to shut down purging and cold start are optimized using starting time and reverse polarity cell count as optimization objectives. The optimal conditions for cold start include a current density of 0.5 A/cm2, voltage of 0.45 V, purging time of 180 s, and stack temperature (during purging) of 60℃. Furthermore, the ambient temperature boundary is determined as −25℃–−30℃ for a successful cold start without auxiliary heating in the stack.

Multi-rotor drones, a kind of unmanned equipment which is widely used in the military, commercial consumption and other fields, have been developed very rapidly in recent years. However, their short flight time has hindered the expansion of their application range. This can be addressed by utilizing hydrogen fuel cells, which exhibit high energy density, strong adaptability to ambient temperature, and no pollution emissions, as the power source. Accordingly, the application of hydrogen fuel cells as the power source in multi-rotor drones is a promising technology that has attracted significant research attention. This paper summarizes the development process of hydrogen fuel cell multi-rotor drones and analyzes the key obstacles that need to be addressed for the further development of hydrogen fuel cell multi-rotor drones, including structural light weight, hydrogen storage methods, energy management strategies, thermal management, etc. Additionally, prospects for the future development of hydrogen fuel cell multi-rotor drones are presented.
