The objective of this study is modeling and investigating the implementation of solid oxide fuel cell (SOFC) system in power supply system of a ship from the operational and efficiency point of view. Motivation for this subject are the environmental regulations for reduction of emissions in shipping industry. In this paper a model of a solid oxide fuel cell (SOFC) stack is presented, as well as simulation results from its operation within a power supply system onboard a large cruise ship. The work has been conducted by SimulationX (a multi-domain software based on Modelica). The stack model of the fuel cell includes electrochemical and thermal behaviour, considering ohmic, activation and concentration losses. For the usage of different fuels, the complete model of the SOFC system contains an autothermal reformer, a catalytic burner and heat exchangers. The power supply system for a one-week journey of a cruise ship is simulated and the efficiency and fuel consumption of different power plant layouts are compared and discussed.
