... promising technologies since they can produce electricity directly from fuel and generate waste heat that is generally used in the gas turbines (GTs) to promote the general performance of the thermal power plant [ 1 – 4 ]. Emerging technologies such as SOFC-GT hybrid system have received much interest...

... fuel cell-gas turbine (SOFC-GT) hybrid system. The ejector model, SOFC model, and other component models and the validation were conducted to investigate the performance of the hybrid system with anode and cathode ejectors. The geometric parameters of the ejectors were designed to perform the anode...

...Paolo Pezzini; Kenneth M. Bryden; David Tucker This paper evaluates a state-space methodology of a multi-input multi-output (MIMO) control strategy using a 2 × 2 tightly coupled scenario applied to a physical gas turbine fuel cell hybrid power system. A centralized MIMO controller was preferred...

...Y. Haseli Optimum pressure ratios of a regenerative gas turbine (RGT) power plant with and without a solid oxide fuel cell are investigated. It is shown that assuming a constant specific heat ratio throughout the RGT plant, explicit expressions can be derived for the optimum pressure ratios leading...

...) hybrid system in comparison with other technologies. The study investigated three alternative options in order to meet the user’s demand: internal combustion engine, gas turbine, and a hybrid system (molten carbonate fuel cells and gas turbine, MCFC-HS), which is currently under development by Ansaldo...

...Fumihiko Yoshiba A module part of a 7 MW class centralized molten carbonate fuel cell/gas turbine (GT) combined system has been tested. Since the designed (GT) working pressure is 1.2 MPa , the operating pressure of the module was high ( 1.2 MPa ) . In order to realize a high steam-reforming...

...Fabian Mueller; Faryar Jabbari; Jacob Brouwer; Rory Roberts; Tobias Junker; Hossein Ghezel-Ayagh A bottoming 275 kW planar solid oxide fuel cell (SOFC) gas turbine (GT) hybrid system control approach has been conceptualized and designed. Based on previously published modeling techniques, a dynamic...

...S. Campanari; P. Iora; P. Silva; E. Macchi This paper investigates the thermodynamic potential of the integration of molten carbon fuel cell (MCFC) technology with gas turbine systems for small-scale (sub-megawatt or sub-MW) as well as large-scale (multi-MW) hybrid cycles. Following the proposals...

...) stack that is integrated into a SOFC/GT pressurized hybrid system. Analyses are focused on the bottoming part of the cycle, where the gas turbine (GT) has the role of properly managing airflow to the SOFC stack for various loads and at different ambient conditions. Analyses were accomplished using two...

... indicated for complex cycle analysis and cycle optimization, where a complete 3D stack analysis may be limited to selected cases. Then, the model is applied to the off-design analysis of hybrid cycles based on a recuperated gas turbine arrangement where variable pressure ratios and fuel supply conditions...

...Rodolfo Taccani; Diego Micheli Pressurized high temperature fuel cells and gas turbine integrated power systems are receiving growing attention as capable of reaching very high electrical conversion efficiency even in small size power plants. In this system the fuel and the oxidant (air) enter...

... temperature fuel cells like solid oxide fuel cells (SOFCs), especially in combination with gas turbines (GTs), promises remarkable room for improvement in the areas mentioned, compared to other state-of-the-art technologies. But design and handling of such complex plants require efficient control strategies...
