An online energy management system (EMS) is essential for these hybrid systems, it controls energy flow and ensures optimal system performance. Key aspects include fuel efficiency and mitigating FC and battery degradation. . Abstract—In recent years, fuel cell/battery hybrid systems have attracted substantial attention due to their high energy density and low emissions. For example: Lithium-ion for baseline power, supplemented by ultracapacitors for. . To improve the fuel cell durability of the hydrogen Electric Multiple Units, this paper proposes a novel multi-stack fuel cell hybrid system energy management strategy in consideration of fuel cell degradation. Key aspects. .
