“…SOFC systems have been reviewed over time [42][43][44][45][46], with particular attention to the constituent materials and the fabrication techniques [47][48][49]. The SOFC/turbine hybrid system has also attracted a lot of attention and produced extensive research [50][51][52], which has contributed to an ever better understanding of this technology and has identified future challenges to be faced in order to improve it.…”

“…The plants can be differentiated according to the reaction temperatures; those that operate at a temperature higher than 1000 • C react faster, while those operating at temperatures of 350-700 • C have a very long reaction time, even 24 h. Therefore, it is evident that the range of operating temperature is very similar to that of SOFC, which can provide its waste heat to the gasifier for its internal aims. The generalized gasification reaction of biomass is reported in (52). The molecular formula of dry biomass is reported as CH p N q O r , considering an aggregate of hydrogen, carbon, nitrogen, and oxygen.…”

On the Technology of Solid Oxide Fuel Cell (SOFC) Energy Systems for Stationary Power Generation: A Review

This paper presents a comprehensive overview on the current status of solid oxide fuel cell (SOFC) energy systems technology with a deep insight into the techno-energy performance. In recent years, SOFCs have received growing attention in the scientific landscape of high efficiency energy technologies. They are fuel flexible, highly efficient, and environmentally sustainable. The high working temperature makes it possible to work in cogeneration, and drive downstream bottomed cycles such as Brayton and Hirn/Rankine ones, thus configuring the hybrid system of a SOFC/turbine with very high electric efficiency. Fuel flexibility makes SOFCs independent from pure hydrogen feeding, since hydrocarbons can be fed directly to the SOFC and then converted to a hydrogen rich stream by the internal thermochemical processes. SOFC is also able to convert carbon monoxide electrochemically, thus contributing to energy production together with hydrogen. SOFCs are much considered for being supplied with biofuels, especially biogas and syngas, so that biomass gasifiers/SOFC integrated systems contribute to the “waste to energy” chain with a significant reduction in pollution. The paper also deals with the analysis of techno-energy performance by means of ad hoc developed numerical modeling, in relation to the main operating parameters. Ample prominence is given to the aspect of fueling, emphasizing fuel processing with a deep discussion on the impurities and undesired phenomena that SOFCs suffer. Constituent materials, geometry, and design methods for the balance of plant were studied. A wide analysis was dedicated to the hybrid system of the SOFC/turbine and to the integrated system of the biomass gasifier/SOFC. Finally, an overview of SOFC system manufacturing companies on SOFC research and development worldwide and on the European roadmap was made to reflect the interest in this technology, which is an important signal of how communities are sensitive toward clean, low carbon, and efficient technologies, and therefore to provide a decisive and firm impulse to the now outlined energy transition.

“…This is why many researchers have been working for years in order to assess the most appropriate type of application [8][9][10][11]. Other types of similar systems, studied with the same approach, are those that focus more on evaluating the potential for residential cogeneration systems (SOFC-CHP) [12], those that evaluate coupling between SOFC and gas turbine of greater power (SOFC-GT) [13][14][15], or those that take into account molten carbonates fuel cell (MCFC) instead of SOFC [16][17][18][19][20][21][22]. In the same field specific SOFC-MTG can vary the nature of the fuel (which in this case is pure methane but which may be, e.g., synthesis gas or biomass) [14,[21][22][23][24][25][26][27] and there are also those that try, despite the fact that the state-of-the-art technology in question is not consolidated, a first economic evaluation [27,28].…”

The study of a hybrid system obtained coupling a methane fuelled gas microturbine (MTG) and a solid oxide fuel cell (SOFC) was performed. The objective of this study is to evaluate the operation conditions as a function of the independent variables of the system, which are the current density and fuel utilization factor. Numerical simulations were carried out in developing a C++ computer code, in order to identify the preferable plant configuration and both the optimal methane flow and the current density. Operation conditions are able to ensure elasticity and the most suitable fuel utilization factor. To confirm the reliability of the models, results of the simulations were compared with reference results found in literature.
