“…Various optimization techniques have been presented in the literature. Single-level modeling aims to optimize the entire system as a whole [21], while multi-level modeling seeks to simultaneously optimize multiple subsystems [22,23]. Calise et al [21] argue that single level optimization produces similar results to multi-level efforts with less difficulty.…”

“…Chan et al [22] considered a 1.3 MW plant, which consisted of a SOFC stack with 40,000 tubular cells. Arsalis [21] considered SOFC stacks up to 8.5 MW for a SOFC-GT-ST hybrid system. Their SOFC stack was modeled up to 1100 °C and 10 bar.…”

“…However, there are practical issues that must be considered, such as localized hotspots and unbalanced loading on each stack. Singhal and Kendall [26] and Larminie and Dicks [27] expect that practical SOFC systems will be scaled up from 100 kW to 10 MW prior to commercialization of the technology [21].…”

“…The SOFC model is validated using experimental data published in References [21,30,31] (Figure 3). Experimental data are based on 89% H 2 and 11% H 2 O at the anode fuel, and operation at 1000 º C and 1 atm.…”

Power generation using gas turbine power plants operating on the Brayton cycle suffers from low efficiencies. In this work, a solid oxide fuel cell (SOFC) is proposed for integration into a 10 MW gas turbine power plant, operating at 30% efficiency. The SOFC system utilizes four heat exchangers for heat recovery from both the turbine outlet and the fuel cell outlet to ensure a sufficiently high SOFC temperature. The power output of the hybrid plant is 37 MW at 66.2% efficiency. A thermo-economic model predicts a payback period of less than four years, based on future projected SOFC cost estimates.

“…An internal reforming hybrid SOFC/GT system could get an electrical efficiency more than 60 % (Chan, et al,2002).The SOFC/GT hybrid system can be extended to multi MW power generation system depending upon commercially available gas turbines (Song, et al, 2006). The SOFC systems were also analyzed by Calise, et al (Calise, et al, 2006). Zhang et al have presented the integration strategies for SOFCs (Zhang, et al, 2010).Douvartzideset al revealed an energyexergy analyses to optimize the operation conditions of a SOFC/GT power plant considering only hydrogen oxidation within the fuel cell and rejecting the effect of the cell losses instead of methane reforming and carbon monoxide conversion (Douvartzides, et al, 2004).Granovskii et al, have compared the performance of two combined SOFC-GT systems (Granovskii, et al, 2007).…”

Insbesondere bei Gewerbebauten umfassen die Deckensysteme ca. 15 % bis 20 % der Rohbaukosten und sind somit in einem entscheidenden Umfang baupreisbestimmend. Halbfertigteile und der Fertigteilbau mit kleinteiligen Elementen, deren Montage auch mit üblichen Hochbaukränen gelingt, bieten hierzu immer noch erhebliche Optimierungspotenziale in Beton, Bewehrung und Rüstung. Insbesondere innovative Anschlussdetails erlauben einfache Montagekonzepte. Anhand von Berechnungen und ausgeführten Beispielen können die Konzepte erläutert werden. Optimization concepts for ceiling systems – of semi‐finished elements to prefabricated constructions Particularly by industry buildings the structural system covers 15 % to 20 % of the rough work costs, these are consequently price‐setting in a high range. Half‐prefabricated and prefabricated building methods with small elements, whose installation works also with common building cranes still offer heavy optimizing potential on concrete, reinforcement and armament. Especially innovative connecting details allow simple installation concepts. The concepts can be clarified on the basis of calculations and conducted examples.
