The study demonstrates the feasibility of utilizing an overexpansion gas turbine cycle to recover waste heat from the exhaust gases of fuel cells, thereby improving the energy system's efficiency and enhancing the reliability of its key components. A novel hybrid system configuration has been developed, based on fuel cells and a regenerative overexpansion gas turbine, achieving an efficiency of 60–70%, significantly surpassing the efficiency of modern marine power generation systems (turbo- and diesel-generators). A mathematical model of the working process in a plasma-chemical afterburner was developed, capable of predicting the energy and emission characteristics of the latest fuel-burning devices in gas turbine systems. Based on this model, optimization of the geometric and operational parameters of advanced combustion chambers for marine and stationary gas turbines was conducted. Unlike existing global analogs, the study for the first time demonstrates the possibility of stabilizing the combustion of exhaust gases from solid oxide fuel cells and their efficient afterburning with minimal emissions of toxic components in a plasma-chemical device. This is achieved through the intensifying effect of active products of plasma-chemical transformations on the propagation processes of turbulent flames. The use of a contact scheme for the gas turbine installation increases the system's calculated (absolute) efficiency by 3.8–4.1% (depending on the method of steam supply to the thermal scheme elements) compared to the traditional regenerative gas turbine scheme. Thus, the proposed solutions can be effectively employed in the development of high-performance and competitive next-generation domestic engines.
