One option therefore is the combination of SOFC with a recuperated MGT. Here, a new strategy for selecting the system parameters, such as the operating temperature of the SOFC, the turbine inlet temperature and the pressure ratio of the hybrid system, is presented. By introducing the heat ratio between the heat required to increase the process gas to the SOFC operating temperature and the heat required to raise the SOCF exhaust gas to the TIT, it was found that high efficiency (approx. 68\%) is realisable in a compact hybrid system today. Analysis also shows that the HEX-technology is needed to improve the system effectiveness. Also, high recirculation rates with lower TIT can be considered as the future development direction. In addition, a sample configuration of an oil-free MGT rotor unit with high speed foil bearings is presented.}, language = {en} } @misc{MartinLehmannSchlaegeretal., author = {Martin, Frank and Lehmann, Mario and Schl{\"a}ger, Peter and Sack, Ulrich and Anderer, Ursula}, title = {Differentiation capacity of chondrocytes in microtissues depends on TGF-ß subtyp}, series = {Journal of biochips \& tissue chips : JBTC}, volume = {S2}, journal = {Journal of biochips \& tissue chips : JBTC}, number = {002}, issn = {2153-0777}, doi = {10.4172/2153-0777.S2-002}, pages = {11}, language = {en} } @inproceedings{LehmannVossMartinetal., author = {Lehmann, Mario and Voß, Fr{\"a}nzi and Martin, Frank and Schl{\"a}ger, Peter and Anderer, Ursula}, title = {Chondrogenic microtissues in the lab \& for the clinic}, series = {3D cell culture 2016, book of abstracts, DECHEMA Biotechnologie}, booktitle = {3D cell culture 2016, book of abstracts, DECHEMA Biotechnologie}, publisher = {DECHEMA e.V.}, address = {Frankfurt am Main}, isbn = {978-3-89746-182-6}, pages = {52 -- 53}, language = {en} } @misc{BergHimmelbergLehmannetal., author = {Berg, Heinz Peter and Himmelberg, Axel and Lehmann, Mario and D{\"u}ckershoff, Roland and Neumann, Mathias}, title = {The Turbo-Fuel-Cell 1.0 - family concept - Compact Micro Gas Turbine (MGT) - Solid Oxide Fuel Cell (SOFC) energy converters in the 100 - 500 kW electrical power range for the future}, series = {IOP conference series : Materials Science and Engineering}, volume = {297}, journal = {IOP conference series : Materials Science and Engineering}, issn = {1757-899X}, doi = {doi:10.1088/1757-899X/297/1/012004}, pages = {15}, abstract = {The "Turbo-Fuel-Cell-Technology" has been described as a MGT-SOFC hybrid system consisting of a recuperated micro gas turbine (MGT) process with an embedded solid oxide fuel cell (SOFC) subsystem. SOFC stacks are connected to "SOFC stack grapes" and are equipped with the so called HEXAR-Module. This module is composed of a high-temperature heat exchanger (HEX), an afterburner (A) and a steam reformer (R). The MGT-concept is based on a generator driven directly by the turbomachine and a recuperator, which returns the exhaust heat to the pressurized compressor outlet air. This provides the necessary base for a highly effective, pure MGT process and the "MGT-SOFC-high-efficiency process". This paper describes the concept and the thermodynamic background of a highly effective and compact design of the "Turbo-Fuel-Cell 1.0-Family" in the electrical performance class from 100 to 500kW. The technological state of the system is shown and a rating of the system with comparative parameters is discussed. It becomes visible that all necessary basic technologies should be available and that the technology (for stationary applications) can have the "entry into services (E.I.S.)" in the next 10 years. The MGT-SOFC performance map under different operation conditions is discussed. This article also provides an overview of the research on MGT-SOFC-Systems and the scenario of an energy supply network and a mobile energy conversion of the future introduction.}, language = {en} }
