Responsible coordinator of the module PH2068 in the version of SS 2018 was Werner Schindler.

Content, Learning Outcome and Preconditions

Content

  • Global energy issues and the role of fuel cells in this scenario
  • Principles of fuel cells
  • Overview of dfferent types of fuel cells
  • Thermodynamic and electrochemical fundamentals related to fuel cells: equilibrium voltages (Nernst equation), conversion efficiencies
  • Fundamentals of electrocatalysis, electrode kinetics (Butler-Volmer relation), current-voltage curves of fuel cells
  • Overview of applications of fuel cells (space, military, mobile, etc.)
  • Anode reactions in fuel cells (hydrogen, methanol, ethanol oxidation)
  • Cathode reaction in fuel cells (oxygen reaction)
  • Polymer electrolyte fuel cells
  • Direct methanol fuel cells and direct alcohol fuel cells
  • Solid oxide fuel cells; reformation processes; direct fuel cells
  • Stationary applications of fuel cells
  • Automotive and transport applications of fuel cells
  • Production and storage of hydrogen in a hydrogen economy

Learning Outcome

After participation in the module the student is able to:

  1. Explain the thermodynamic and electrochemical fundamentals of fuel cells
  2. Discuss the pro and contras of the various fuel cell types
  3. Discuss environmental and economic issues related to fuel cells (e.g. efficiency, necessary infrastructure for fuel cell based economies)

Preconditions

In general no major preconditions in addition to the requirements for the Master’s program in Physics. However, basic knowledge in chemical agents and chemical reactions would be helpful - although not required.

Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

The learning content is thematically structured presented in the lecture. Special emphasis is laid onto the principal physical and chemical aspects, and their relevance to this field. The exercise is intended to intensify the teached knowledge from the lecture in an interactive way with the students. Either individually or in small work groups. Finally the students shall be able to apply the learned knowledge independently.

Module Exam

Description of exams and course work

There will be an oral exam of about 30 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.

For example an assignment in the exam might be:

  • What is the principle / energetics of a fuel cell?
  • What is the efficiency / loss of a fuel cell?
  • Which role plays the catalyst?
  • Which advantages / disadvantages do various fuels have?

In the exam no learning aids are permitted.

Participation in the tutorials is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

Exam Repetition

The exam may be repeated at the end of the semester.
