Fuel cell systems

Uitgebreide vaknaam	Fuel cell systems
Leerdoelen	In general: the student is able to understand physical and chemical processes taking place in a fuel cell and be able to create conceptual designs of fuel cell systems for different electricity generation applications. More specifically, at the end of the course, the student is able to: 1. Understand the requirements on fuel cell systems given the current energy situation 2. Describe the physical and chemical processes taking place in different types of fuel cells 3. Calculate fuel cell operational voltage and temperature based on thermodynamics balance laws 4. Appraise PEMFCand SOFC fuel cells regarding construction and suitability 5. Select the balance of fuel cell-plant components for particular applications 6. Select fuel-cell fuel processing given overall system requirements 7. Select/Design the sub-components of a fuel-cell system according to the balance of plant components and fuel processing 8. Design, evaluate and select low temperature fuel cell-based systems (focus on fuel cell system thermodynamics) 9. Design, evaluate and select high temperature fuel cell-based systems (focus on fuel cell system thermodynamics)
