“…It allows the SOFC to be put into practice with a gas turbine to produce electrical and thermal energy in hybrid cycles. These hybrid cycles will be competitive with traditional complicated cycles consisting of a gas turbine and a heat recovery steam generator, because the electrical efficiency of the whole system may reach 70% and more (Lemański et al 2004;Cheddie 2010;Saisirirat 2015;Tunca and Kaya 2017;Zaccaria et al 2017).…”

The results of theoretical studies of the possibilities of using hybrid solid oxide fuel cell-gas turbine (SOFC-GT) systems for marine power plants are presented. A 500 kW auxiliary marine power plant scheme using stacks of SOFCs in combination with a regenerative gas turbine operating with overexpansion based on our recent patent application is proposed. The results of mathematical modelling showed the opportunity to obtain a hybrid scheme efficiency of about 55% with the optimal values of the gas turbine compression ratio 2.0-2.2 and the exhauster compressor ratio 1.3-1.4. The application of the considered hybrid SOFC-GT system gives an increase in electrical efficiency by 19% in comparison with a cycle without a gas turbine. The aerodynamic structure of chemically reacting flows in a combustor is determined, as well as the features of the formation of toxic components during the combustion of SOFC off-gas with very low heating value.

Mass-produced, off-the-shelf automotive air compressors cannot be directly used for boosting a fuel cell vehicle (FCV) application in the same way that they are used in internal combustion engines, since the requirements are different. These include a high pressure ratio, a low mass flow rate, a high efficiency requirement, and a compact size. From the established fuel cell types, the most promising for application in passenger cars or light commercial vehicle applications is the proton exchange membrane fuel cell (PEMFC), operating at around 80 °C. In this case, an electric-assisted turbocharger (E-turbocharger) and electric supercharger (single or two-stage) are more suitable than screw and scroll compressors. In order to determine which type of these boosting options is the most suitable for FCV application and assess their individual merits, a co-simulation of FCV powertrains between GT-SUITE and MATLAB/SIMULINK is realised to compare vehicle performance on the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) driving cycle. The results showed that the vehicle equipped with an E-turbocharger had higher performance than the vehicle equipped with a two-stage compressor in the aspects of electric system efficiency (+1.6%) and driving range (+3.7%); however, for the same maximal output power, the vehicle’s stack was 12.5% heavier and larger. Then, due to the existence of the turbine, the E-turbocharger led to higher performance than the single-stage compressor for the same stack size. The solid oxide fuel cell is also promising for transportation application, especially for a use as range extender. The results show that a 24-kWh electric vehicle can increase its driving range by 252% due to a 5 kW solid oxide fuel cell (SOFC) stack and a gas turbine recovery system. The WLTP driving range depends on the charge cycle, but with a pure hydrogen tank of 6.2 kg, the vehicle can reach more than 600 km.

The power sector's concern for high efficiency and output has been pushing for newer thermodynamic systems working on appropriate thermodynamic cycles. For quite some time, direct energy conversion systems are seen as suitable options for power generation. Fuel cells in particular have exhibited potential and efforts are made to ensure the best output from them. Solid oxide fuel cells (SOFC) have direct electricity generation and the rejection of heat occurring simultaneously. The heat going as waste from SOFC can be used for running other energy systems to augment the total output from the combined arrangement having SOFC hybrid cycles. The low-temperature cycles like Kalina cycle, organic Rankine cycle (ORC) have been integrated with SOFC along with gas turbine (GT) based systems and engines. The sole aim of operating SOFC in hybrid mode is to ensure that the net amount of heat getting lost is recovered for overall performance improvement. This paper presents a review of the work done in the field of SOFC based hybrid systems, which is likely to be useful for those interested to continue further studies of SOFC.
