燃料电池-燃气轮机联合循环系统作为舰船电力综合系统优质动力源，具有传统热机不可比拟的高效性。本文针对燃料电池-燃气轮机底层循环构建数学模型，并对其性能进行仿真研究。目前燃料电池单堆功率相较于微型燃气轮机较小，为实现燃料电池与微型燃气轮机的功率匹配，提出多堆燃料电池与燃气轮机联合循环。分析多堆燃料电池与燃气轮机联合循环功率匹配与参数优化，使得系统在不同工况下均保持较高效率。为实现燃料电池-燃气轮机联合动力系统在水面舰艇上的应用打下坚实基础。
The SOFC-GT combined cycle system as the power source of ship has higher efficiency than traditional engine. In this paper, a mathematical model is built for the bottom cycle of SOFC-GT, and its performance is simulated. At present, the power of SOFC is smaller than micro gas turbine. In order to realize the power matching between SOFC and micro gas turbine, a multi stack fuel cell and gas turbine combined cycle is proposed. The system can keep high efficiency under different working conditions by analysing power matching and parameter optimization. It has laid a solid foundation for the application of SOFC-GT combined power system on ships.
