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)
Omschrijving Electrochemical power production, open circuit voltage and reversible voltage, the Nernst equation, the effect of pressure and gas concentration, actual fuel cell voltage and efficiency, fuel and oxidant utilization.

Fuel cell irreversibilities, activation losses, tafel equation, fuel crossover and internal currents, ohmic losses, concentration losses, optimum current density.

Different types of fuel cells:

1. Proton Exchange Membrane Fuel Cells (PEMFC): electrolyte materials and structure, electrode materials and structure, gas channels and separator plates, water management, cell cooling and air supply, considerations with regard to system design (fuel and air conditions at cell inlet), construction of stacks.

2. High temperature fuel cells, internal reforming, fuel utilization, bottoming cycles, the use of exergy and pinch technology.

3. Solid Oxide Fuel Cell (SOFC): electrolyte materials, electrode materials and structure, cell configuration and design (flat plate and tubular configuration), stack design, internal reforming and prereforming, cell and stack performance, system design options.
- Fuel production processing: desulphurisation, steam reforming, partial oxidation, autothermal reforming, high temperature and low temperature shift, CO removal, combustion of residual fuel, gasification and gas cleaning, heat integration. Electrolysis and reversible/regenerative fuel cells and fuel production, energy storage
- System thermodynamics, exergy losses in fuel cell systems and components, systems for stational power production and transport (land, air and water)
