Abstract: ABSTRACT Solid oxide fuel cells (SOFCs) have shown great promise as a means of producing clean and efficient electricity. This review focuses on doing a comprehensive analysis of SOFC-based experimental hybrid power systems, focusing on their thermodynamic (energy and exergy), economic, and environmental aspects. Performance of a standalone SOFC system can be improved by combining it with other power technologies, i.e. gas turbines (GTs), internal combustion engines (ICEs), or some other waste heat recovery cycles, which provide greater system flexibility and load-following capabilities. Maximum deviation between simulation results and experimental results have been reported within 10%. SOFC-GT hybrid system offers electrical efficiency 50–60%, exergy efficiency up to 52%, emission of CO2 376.9 kg/MWh, and total cost of the system as 25 $/h. Most of the literatures have shown CO2 emission of SOFC-based hybrid system in the range of 250–350 kg/MWh. Economic and environmental studies of the hybrid systems is essential for widespread adoption and future development.

TL;DR: In this paper, the authors provide a comprehensive review with respect to the structure, chemistry, design and selection of materials, underlying mechanisms, and performance of each SOFC component, and it opens up the future directions towards pursuing SOFC research.

TL;DR: A comparative study of basic design, working principle, applications, advantages and disadvantages of various technologies available for fuel cells is presented in this article, where the results indicate that fuel cell systems have simple design, high reliability, noiseless operation, high efficiency and less environmental impact.

TL;DR: A comprehensive review of the research in this area in the past one decade is presented in this paper, where an attempt has been made to present a comprehensive review on the research on the unit sizing, optimization, energy management and modeling of hybrid renewable energy system components.

TL;DR: In this article, the authors provide a detailed analysis of such optimum sizing approaches in the literature that can make significant contributions to wider renewable energy penetration by enhancing the system applicability in terms of economy.
