Description

Development, investigation and modelling of a micro reformer as part of a system for off-grid power supply with PEM fuel cells Entwicklung, Untersuchung und Modellierung eines Mikroreformers als Teil eines Systems zur netzfernen Stromversorgung mit PEM-Brennstoffzellen Von der Fakultät für Maschinenbau, Elektrotechnik und Wirtschaftsingenieurwesen der Brandenburgischen Technischen Universität Cottbus zur Erlangung des akademischen Grades Doktor-Ingenieur genehmigte Dissertation von Dipl.-Ing. Lisbeth Rochlitz geboren am 16.03.1977 in Hamburg Vorsitzender: Prof. Dr.-Ing. H. Schwarz Gutachter: Prof. Dr.-Ing. H. J. Krautz Gutachter: Prof. Dr.-Ing. W. Witt Tag der mündlichen Prüfung: 18.11.2008 Abstract I Abstract In this thesis a micro reformer fuel cell system ( μRFCS) for 300 W off-grid power supply, fuelled elwith bioethanol, was simulated, designed, developed and investigated in a test-rig. First a literature study was carried through to point out the specific characteristics of micro reforming, the most important being heat transfer, and present the systems currently under research and already on the market. As a next step, the processes of the RFCS were simulated with the commercial simulation tool CHEMCAD. This comprised thermodynamic equilibrium simulations for the separate reactions of steam reforming, water gas shift and selective methanation.
