Simulation Study on a fuel cell/battery hybrid electric propulsion system for ships

다국어 초록 (Multilingual Abstract)

This study focuses on modeling and simulating the components of a fuel cell/battery hybrid electric propulsion ship. The components were modeled and implemented in a simulation environment. Fuel cell systems can be broadly divided into three main subsystems: a polymer electrolyte membrane fuel cell (PEMFC) stack, fuel supply system, and a cooling system. The power system consists of a battery, converter and inverter units, an electric motor, and an energy management system (EMS) algorithm. To maintain system power balance, the EMS algorithm coordinates the fuel cell, battery, and load demands of the ship. In this study, a hybrid system combining a PEMFC and battery was developed by modeling each component and integrating them into a simulation environment.
The simulation results confirmed that in the implemented system, the power demand generated by the operational profile, power produced by the fuel cell, and charging and discharging power of the battery were controlled to maintain balance.
