SOFC/GT hybrid system is proposed as one of the advanced power systems of future ships due to its high efficiency, low emission and fuel flexibility. However, how to efficiently reform marine diesel into H2 is the key to maintaining the operation of SOFC/GT. This paper studies the influence of operating parameters such as S/C, temperature and pressure of ship SOFC/GT hybrid system on H2 production characteristics of marine diesel reforming through numerical simulation and experimental analysis. The results show that under the variable working conditions, the H2 production increases with temperature and the carbon deposition decreases. The increase of S/C promotes the increase of H2 yield and inhibits carbon deposition. Pressure has a negative effect on H2 production. The research results can provide basic technical support for the safe and efficient operation of the SOFC-GT hybrid power system on ships and the continuous supply of fuel.

“…During this period, fuel cell technology began to receive widespread attentions, leading to numerous research and projects to explore the potential of SOFC/GT system [23]. Currently, the literature about SOFC/GT primarily centers on thermodynamics investigation [24][25][26], multi-objective optimization [27][28][29], system configuration [30,31], eco-technoeconomic analysis [32], numerical study [33][34][35], control system design [36][37][38][39][40], renewable energy source utilization [41], mobile applications [42], CO 2 capture [27,43], and other prospective research [44]. However, the reviews about SOFC/GT hybrid systems have rarely been reported, thus this work mainly focuses on this topic.…”

“…A control structure of the total system has been developed at the cost of the efficiency of the SOFC-GT-based autonomous power system. 22 Besides, a novel control approach has been proposed by combining the multi-control loops with the coordinated protection loops, 23 which achieves following of the fast load and safe transient operation of the SOFC system. The principle of an RL-based energy management strategy (EMS) was proposed, which is used for the application of an RL-based technique for controlling fuel cell hybrid systems.…”
