A multi-physics process simulation software has become a fundamental instrument for managing the entire lifecycle of a product, from ideation to end-of-life. It accelerates the design and optimization of large systems, aiding in decision-making, engineering, and operation. With the recent growth of renewable energy systems and the push towards energy transition, it is necessary to develop new modules into the simulation tools to include new technologies. Siemens is investing on that and is currently developing new modules for the inclusion of SOFC in their process simulation software Simcenter Amesim. In this context, the goal of this thesis is to develop and optimize a simulation model of a micro-combined heat and power (m-CHP) system based on the use of the Solid Oxide Fuel Cell (SOFC) for residential application.
