“…However, a 100 kW output was used in a practical test bed. The MBOP was pretreated to make a better chemical reaction between the fuel gas and air, which concludes a pre-former, heater, humidifier, valves, pump, and blower [39]. The specifications are listed in Table 6.…”

The need for technological development to reduce the impact of air pollution caused by ships has been strongly emphasized by many authorities, including the International Maritime Organization (IMO). This has encouraged research to develop an electric propulsion system using hydrogen fuel with the aim of reducing emissions from ships. This paper describes the test bed we constructed to compare our electric propulsion system with existing power sources. Our system uses hybrid power and a diesel engine generator with a combined capacity of 180 kW. To utilize scale-down methodology, the linear interpolation method is applied. The proposed hybrid power source consists of a molten carbonate fuel cell (MCFC), a battery, and a diesel generator, the capacities of which are 100 kW, 30 Kw, and 50 kW, respectively. The experiments we conducted on the test bed were based on the outcome of an analysis of the electrical power consumed in each operating mode considering different types of merchant ships employed in practice. The output, fuel consumption, and CO2 emission reduction rates of the hybrid and conventional power sources were compared based on the load scenarios created for each type of ship. The CO2 emissions of the hybrid system was compared with the case of the diesel generator alone operation for each load scenario, with an average of 70%~74%. This analysis confirmed the effectiveness of using a ship with a fuel-cell-based hybrid power source.

“…The high working temperature of MCFC offers advantages such as fuel flexibility, utilization of cheap catalysts, and the possibility of co-generation of heat and power (CHP) and fuel cell combined cycles (FCCC) operation with high efficiency (Massardo and Bosio, 2002;Milewski et al, 2010;Varbanov et al, 2006;Yoshiba, 2008). Hydrogen is normally obtained by steam reforming (reaction (4)) of natural gas, syngas from gasification of coal or biomass, or biogas.…”

“…The MCFC as the hydrogen, electric power, and heat trigeneration system [8] has been studied by many methods to propose the MCFC as the carbon capture system in fossil fired power plants [9,10], examine the effect of the materials [11] and thickness [12] of electrodes and reactant [13] on the stability of the MCFC, and model the performance characteristics of the MCFC [14,15]. When a MCFC is operated, there are the waste heat produced in the system [16] and the residual hydrogen from the anode of the fuel cell [17], the general method to deal with the heat from MCFC is to release it into the environment [18,19].…”

a b s t r a c tA novel model of the molten carbonate fuel cell (MCFC) and gas turbine (GT) hybrid system with direct internal reforming is established, where the fuel cell and the auxiliary burner are taken as the heat reservoirs of the GT. Expressions for the power output and efficiency of the hybrid system are derived by considering various irreversible losses resulting from the overpotentials in the MCFC, the heat leakage in the auxiliary burner, and the finite-rate heat transfer and compression, expansion, and regeneration processes in the GT. The effects of some key parameters including the molar fraction of the oxygen in the oxidant, the utilization factor of the hydrogen in the MCFC on the performance of the hybrid system are revealed. It is found that the efficiency of the hybrid system will be increased by adding the utilization factor of the hydrogen, and the maximum power output of the hybrid system will be achieved when the utilization factor of the hydrogen is equal to 0.78. Moreover, the flowing rates of the syngas and oxidant and the molar fraction of the oxygen in the oxidant are determined under the optimal efficiency or maximum power output of the hybrid system.
