PhD course in introduction to low-temperature fuel cells and electrolyserTechnical University of DenmarkGeneral course objectives: The student will learn how fuel cells and electrolysers work, will be able to describe theoretically some of the important features of especially low-temperature fuel cells and low-temperature electrolysis cells, and will be able to describe and interpret electrochemical properties of the cells. The student will learn how they are made and for which applications each cell type is more appropriate and what is required from a system point of view to operate it. The student will also obtain a fair view on the difficulties that exist for the individual types such as degradation mechanisms and demands for fuel and air quality. The student will learn the electrochemical and thermodynamical basic principles of the operation of low-temperature fuel cells (LTFC) and electrolysis cells (LTEC), will be able to describe the requirements put forward on the materials, will learn the principles of the conduction mechanisms in the materials used for the main components, will be able to describe theoretically and interpret electrochemical processes occurring in LTFC and LTEC, will learn about cell- and stack designs and manufacturing methods, will be able to describe the main degradation mechanisms occurring in LTFC and LTEC, and will understand critical issues in the selection of materials and components for cells. Furthermore, the student will come to know about the advantages and disadvantages of different LTFC and LTEC compared with other energy technologies, and will be acquainted with various designs and their advantages and disadvantages as well as application areas. The student will gain experience with characterization methods such as electrochemical methods and structural analysis methods. In addition, the student will participate in group work on own ideas on possible applications of LTFC and/or LTEC. Learning objectives: A student who has met the objectives of the course will be able to:
