The invention belongs to the technical field of aero-engines, and particularly relates to an aero-engine driven by a fuel cell, which comprises a first driving motor, a ducted fan, a first-stage fuel cell stack, a second-stage fuel cell stack and a hydrogen supply system, the first driving motor drives the ducted fan to rotate to generate most airflow which is directly discharged backwards to generate main thrust; a small part of the gas flow firstly enters the first-stage fuel cell stack to provide oxygen for a cathode of the first-stage fuel cell stack and cool the stack, and the gas flow continuously flows into the second-stage fuel cell stack after flowing through the first-stage fuel cell stack to provide oxygen for a cathode of the second-stage fuel cell stack and cool the stack; according to the aero-engine driven by the fuel cell, the structure of the fuel cell and the structure of the aero-engine are subjected to fusion design, and the fuel cell can still be cooled in an air cooling mode under the condition that the total output power of the fuel cell exceeds 5 kW.

    本发明属于航空发动机技术领域,具体涉及一种采用燃料电池驱动的航空发动机,其包括:第一驱动电机,涵道风扇,第一级燃料电池电堆,第二级燃料电池电堆,氢气供应系统,第一驱动电机带动所述涵道风扇旋转产生的气流大部分直接向后排出产生主要推力;小部分气流首先进入第一级燃料电池电堆,为第一级燃料电池电堆的阴极提供氧气并冷却电堆,气流在流经第一级燃料电池电堆后,继续流入第二级燃料电池电堆,为第二级燃料电池电堆的阴极提供氧气并冷却电堆;本发明所述的采用燃料电池驱动的航空发动机将燃料电池与航空发动机的结构进行融合设计,实现在燃料电池总输出功率超过5 kW的条件下,仍然能采用风冷方式对燃料电池冷却。
