【Abstract】 Aiming at the development requirements of compact and carbon-free ship power generation system in the future, this paper proposed a novel ribbed ammonia cracking hydrogen production/catalytic combustion integrator, based on which the NH₃-fueled ship solid oxide fuel cell（SOFC） power generation system was designed, the mathematical model of fuel cell power generation system was constructed for theoretical analysis and experimental verification, and the power generation characteristics and parameter influence rules of this system were obtained under variable operating conditions. The results show that the designed power system′s output power is 96 kW and efficiency is 57.92%, which meets the target ship load requirement. Under variable operating conditions, the anode tail gas cycle ratio has the greatest influence. When the cycle ratio of system increases from 0 to 10%, the voltage increases by 0.08 V. When N/O increases from 0.31 to 0.53, the voltage increases by 0.04 V, and the fuel utilization rate is least impacted. The experimental characteristics of ammonia cracking for hydrogen production in the power generation system thermal environment of 400-750 ℃ show that 100% hydrogen production can be achieved when the temperature is greater than 678 ℃.更多还原
