Sammanfattning
The main purpose of this thesis is to explore and review the possibility of a 0D / 1D simulation to support the general fuel cell system design and development. The thesis also encapsulates the needs of the users by analyzing the type of use and adapting the system for it. The focus of this project is to model a fuel cell system. The scale of this project encloses to:
● Develop, build and verify models for the balance of Plant (Fuel (Anode) system, Air (Cathode) system, Coolant system). Implementation of a (simplified) controls strategy.
● Understand required component and measurement data for modelling and validation of the system.
● Evaluation of the potential to predict system behaviour and performance in real steady-state operation mode.
● Comparison of the evaluated approaches acc. to defined criteria and recommendations.
The model of the fuel cell system is designed and the system simulations are carried out in two distinct simulation environments. Modelon Impact and GT- Suite are the two simulation tools that are investigated. The simulation is first carried out in Modelon Impact simulation environment and the results are evaluated with how detailed and specific design can be generated. The same approach is carried out in GT- Suite. The above-mentioned software is compared on various parameters to improve the system simulation of fuel cells.
The thesis is intended to be a foundation for the design and simulation of a fuel cell and the working system around it. The results of this thesis are presented in a manner as to function as a foundation for the decision-makers. The results are based particularly on technical aspects, as the economic part is up to the decision-maker to look into
