The automotive industry is adapting to stricter emission standards, driving the need for greener alternatives. Modular hybrid vehicle (HV) platforms combine various energy sources, including electric motors, combustion engines, batteries, and fuel cells (FCs). However, FC durability remains a concern due to deteriorations during operation. This study utilizes Matlab-Simulink to model, characterize, and control FCs, addressing key issues like flooding, cold starts, and carbon monoxide poisoning. The proposed FC model comprises the cathode, anode, and membrane. Strategies are discussed for managing membrane water, dealing with cold starts, countering FC poisoning, and ultimately enhancing FC performance and lifespan.
