Polymer electrolyte membrane fuel cells (PEMFCs) have gained significant global attention for their potential applications in the transportation sector, encompassing passenger cars as well as heavy-duty vehicles. The unique operating conditions of these vehicles, characterized by frequent load changes, varying ambient conditions, and mission profiles, demand stringent efficiency and durability requirements. To meet these demands and prevent critical operation, accurate control strategies are essential for managing operating conditions. This chapter focuses on the physicsbased dynamic modeling of PEMFC stacks. It builds upon the analysis conducted in Chapter 14, which primarily explored the physical phenomena occurring in the membrane electrode assembly. The objective is to provide further insights into the influence of geometrical features in real-world cell configurations. Additionally, the chapter addresses the auxiliary subsystems responsible for thermal management, air and hydrogen management, as well as electronic power converters and power trains designed specifically for PEMFC vehicles.

Abstract
Polymer electrolyte membrane fuel cells (PEMFCs) have gained significant global attention for their potential applications in the transportation sector, encompassing passenger cars as well as heavy-duty vehicles. The unique operating conditions of these vehicles, characterized by frequent load changes, varying ambient conditions, and mission profiles, demand stringent efficiency and durability requirements. To meet these demands and prevent critical operation, accurate control strategies are essential for managing operating conditions. This chapter focuses on the physicsbased dynamic modeling of PEMFC stacks. It builds upon the analysis conducted in Chapter 14, which primarily explored the physical phenomena occurring in the membrane electrode assembly. The objective is to provide further insights into the influence of geometrical features in real-world cell configurations.
