The invention discloses an engine driven by a fuel cell. A fuel cell and a traditional engine are designed in a fused mode, a control system of an original fuel cell is fused into an engine control system, an air supply system in the original fuel cell system is abandoned, a fuel cell stack is arranged right behind a propeller, and part of airflow generated by the propeller is introduced into the fuel cell stack; the supply of cathode air and the cooling of the fuel cell stack are realized, and the structural efficiency and the power-to-weight ratio of the engine are greatly improved. Meanwhile, the multi-stage multi-rotor power system is only provided with the propellers and the driving motors, and compared with other multi-stage multi-rotor power systems, the noise is lower; the all-electric propulsion power device is not provided with a heat engine, so that the working temperature of the whole machine is low, and the infrared stealth performance is good; according to the invention, the discharged products are residual fuel, oxygen and water, and various nitric oxides of the traditional power device are avoided, so that zero discharge and no pollution are realized.
本发明公开了一种燃料电池驱动的发动机。本发明将燃料电池和传统发动机融合设计,将原燃料电池的控制系统融合进发动机控制系统之中,并舍弃了原燃料电池系统中的空气供应系统,将燃料电池电堆置于螺旋桨正后方,将螺旋桨产生的一部分气流引入燃料电池电堆中,实现阴极空气的供应及燃料电池电堆的冷却,极大地提高了发动机的结构效率及功重比。同时,本发明只有螺旋桨和驱动电机两个旋转部件,同其他多级多转子动力系统相比噪音更低;本发明为全电推进的动力装置,没有热机,因此整机工作温度低,红外隐身性好;本发明的排放产物为剩余燃料、氧气和水,没有传统动力装置的各种氮氧化物,因此零排放、无污染。
