PhD course in introduction to SOFC and SOEC


Technical University of Denmark


General course objectives:
The student will learn about the electrochemical and thermodynamical basic principles of the operation of solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs), 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 SOFC and SOEC, will learn about cell- and stack designs and manufacturing methods, will be able to describe the main degradation mechanisms occurring in SOFC and SOEC, 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 SOFC and SOEC 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 learn about characterization methods, such as electrochemical methods and structural analysis methods. In addition, the student will in group work on own ideas on possible applications of SOFC and/or SOEC.

Learning objectives:
A student who has met the objectives of the course will be able to:
  • Describe theoretically the electrochemical fundamentals of SOFC and SOEC
  • Describe theoretically the thermodynamical fundamentals of SOFC and SOEC
  • Explain the fundamental mechanisms of the electrochemical reactions at the electrode/electrolyte interfaces of SOFC and SOEC
  • Explain the fundamental mechanisms of conduction of the individual components of cells and stacks
  • Explain the critical parameters in materials selection for SOFC and SOEC
  • Explain the critical parameters for the selection of operating conditions
  • Analyse data describing the electrochemical performance of SOFC and SOEC
  • Explain the main degradation mechanisms of the performance of the SOFC and SOEC
  • Describe advantages and disadvantages of SOFC and SOEC, also in comparison with other energy technologies

Contents:
Theoretical descriptions of the electrochemical and thermodynamical fundamental properties of ceramic-based fuel cells. Materials properties, conduction mechanisms, requirements for the individual components, i.e. the electrolyte material, the anode material and the cathode material, as well as challenges for the assembled cells. Electrochemical characterization and evaluation of cell properties by electrochemical impedance spectroscopy methods. Description/studies of degradation mechanisms for state-of-the-art SOFC and SOEC. Fabrication, cell and stack design and market opportunities will be treated briefly.
