Transcription

1 General Background and Introduction to the course MVKF25 Hydrogen, Batteries and Fuel Cells

2 Primary Energy Sources Fossil Fuels Problems: a) Increasing CO 2 emission b) Global warming c) Transport problems Strong demands worldwide to eliminate the dependence on fossil fuels like oil, natural gas etc

3 Renewable Energy Resources Solar energy Tidal energy Geothermal energy Wind Energy Bio fuels

4 Electrochemical Devices Batteries Fuel Cells Electrolyzer

5 Batteries and Fuel Cells Batteries are a key technology for today s and tomorrow s electronic devices, particularly for electric hybrid vehicles Fuel cells will be a key element in the probable hydrogen economy of the future Batteries and Fuel Cells are in massive and rapidly growing demand as power source for stationary systems, portable devices and electric vehicles. Batteries and Fuel Cells are efficient, vibration free, noiseless, environmentally friendly alternatives to conventional energy sources

18 Some ideas how increased electrification may work

19 Suitable Background courses and Complementary topics Thermodynamics, heat transfer Mass transfer, materials Electrochemistry introduction and necessary stuff will be taught in the course In general suitable for engineering students in mechanical engineering, chemical engineering, engineering physics, ecosystem engineering and others

20 Aims of Course To provide the students with knowledge and understanding concerning hydrogen as an energy carrier and how to produce and store it. Description, applications and analysis of electrochemical devices like batteries, fuel cells and electrolyzers. The basic mechanisms of momentum, heat, mass, charge (ion and current) transport phenomena are analyzed. Thermal management (and water management in low temperature fuel cells) is presented.

21 Course Literature H. Berg, Batteries for Electric Vehicles, Cambridge University Press, UK, 2015 (e book available via Lund University Library) Excerpts from: S. Revankar, P. Majumdar, Fuel Cells, Principles, Design and Analysis, CRC Press, USA, Various material to be downloaded (e.g., Lecture notes and handouts

22 Examination A written exam including mainly theoretical/descriptive questions and simple problems. Maximum 50 p. Passing the exam with grade 3, 40 % of the maximum number of credit points is required. For grade 4, 60 % is needed, for grade 5, 80 % is required. The assignments (home works) concern theoretical issues, literature review of a specific topic or solving of numerical problems. Every student must hand in her/his own solution to every assignment. Up to 5 bonus points can be provided. A brief compulsory project must also be carried out in groups of 2 5 students. The project must be finalized by a brief report (maximum 10 pages, 1 2 pages of Figs., one page of refs.) and presented orally at the end of the course. Up to 20 bonus points. The final grade is based on the written exam, assignments and project.
