“…However, the overall RRFCS scheme is relatively simple, due to the limited number of components, the interaction between the components, which is complex and the system behaviour, which is determined by many parameters [55]. The second-generation device is planned to have a higher electrical power output and higher electrical thermal efficiency compared with the first-generation device [52]. technologies.…”

“…[54,55]), significant issues (related to technology, maturity, complexity and costs) affected the development speed. However, validated solutions for some research issues (cost decrease, SOFC/mGT matching problem and control system) have since been developed [28,47,52]. Hence, an increase of studies and funding resources on SOFC hybrid systems would be essential to provide realistic solutions for the problems [28,44,45,47,60,76,80].…”

This paper reports a review of an environmentally clean and efficient source of energy such as solid oxide fuel cell hybrid systems. Due to climate concerns, most nations are seeking alternative means of generating energy from a clean, efficient and environmental-friendly method. However, this has proven a big hurdle for both academic and industry researchers over many years. Currently, practical and technically feasible solution can be obtained via an integration of a microturbine and a fuel cell (hybrid systems). Combining the two distinct systems in a hybrid arrangement the efficiency of the microturbine increases from 25-30% to the 60-65% range. Hence, this paper outlines an engineering power generation solution towards the acute global population growth, the growing need, environmental concerns, intelligent use of energy with attendant environmental and hybrid system layouts concerning arising problems and tentative proposed solutions. Furthermore, advantages of a solid oxide fuel cell hybrid systems with respect to the other technologies are identified and discussed rationally. Special attention is devoted to modelling with software and emulator rigs and system prototypes. The paper also reviews the limitations and the benefits of these hybrid systems in relationship with energy, environment and sustainable development. Few potential applications, as long-term potential actions for sustainable development, and the future of such devices are further discussed. KeywordsSolid oxide fuel cell; hybrid system; prototypes; modelling with software and emulator rigs; environmentally clean energy; high efficiency.

“…Furthermore, pressurization of the gases and the use of pure oxygen will significantly improve electrode performance. [32][33][34][35] Although the dependence of electrode polarization resistance (R P ) on reactant (O 2 or H 2 ) pressure is relatively weak at high pressure, e.g., R P f p À0.25 , 36 a pressure increase from P ¼ 1 to 10 atm decreases R P by a factor of 0.56.…”

Reversible solid oxide cells (SOCs) are potentially useful for electrical energy storage due to their good storage scalability, but have not been seriously considered due to concerns over round-trip efficiency.Here we propose an SOC storage chemistry where the fuel cycles between H 2 O-CO 2 -rich and CH 4 -H 2rich gases. The unique feature is the formation of CH 4 during electrolysis, a less endothermic process than the usual H 2 -or CO-forming reactions, enabling improved efficiency. Thermodynamic calculations and preliminary experiments show that the CH 4 -rich storage chemistry is produced during SOC operation at reduced temperature ($600 C) and/or increased pressure ($10 atm). Balance of plant storage system requirements are discussed briefly.

“…Several FC-GT hybrid systems have been studied, but only focusing on high-temperature fuel cells such as Solid Oxide Fuel Cells (SOFCs) [106,107] and Molten Carbonate Fuel Cells (MCFCs) [108][109][110][111][112]. Several working prototypes of such systems have been studied from Siemens-Westinghouse [113], Rolls-Royce Fuel Cell Systems [114], and Mitsubishi Hitachi Power Systems [115], etc. [106].…”

High-temperature proton-exchange membrane fuel cells are a promising technology for distributed power generation thanks to their high-power density, high efficiency, low emissions, fast start-up, and excellent dynamic characteristics, together with their high tolerance to CO poisoning (i.e., CO in the feed up to 3%). In this paper, we present an innovative, simple, and efficient hybrid high-temperature proton-exchange membrane fuel cell gas turbine combined heat and power system whose fuel processor relies on partial oxidation. Moreover, we demonstrate that the state-of-the-art fuel processors based on steam reformation may not be the optimal choice for high-temperature proton-exchange membrane fuel cells’ power plants. Through steady-state modeling, we determine the optimal operating conditions and the performance of the proposed innovative power plant. The results show that the proposed hybrid combined heat and power system achieves an electrical efficiency close to 50% and total efficiency of over 85%, while a state-of-the-art system based on steam reformation has an electrical efficiency lower than 45%. The proposed innovative plant consists of a regenerative scheme with a limited power ratio between the turbine and fuel cell and limited optimal compression ratio. Therefore, micro-gas turbines are the most fitting type of turbomachinery for the hybrid system.
