| چکیده مقاله |
| Unmanned aerial vehicles (UAVs), as remote-controlled or autonomous flying devices characterized by high flexibility and mobility, were usually employed to conduct remote sensing and surveillance missions. Recent developments in fuel cell technologies show great potential to increase flight duration of UAVs with satisfactory fuel economy. For UAVs powered by fuel cell propulsion systems, the maneuverability and the power performance may be considerably affected, since fuel cell has some drawbacks such as the long start-up time, delayed response and weak power performance. The integration of fuel cells with other power sources can significantly improve the dynamic load-response, the power performance, and the energy storage capacity of UAV propulsion systems. Fuel cell/battery hybrid power system is a well-known and popular scheme. The fuel cell/battery hybrid propulsion system has the benefits of both fuel cell and battery. The battery can supply the UAV dynamic load requirements, thereby protecting fuel cell from dynamic load changes that might cause fuel cell damage. Applying batteries to the fuel cell UAV power system leads to operating stability of both fuel cell and overall propulsion. In this paper, the fuel cell/battery hybrid system structures developed for UAVs are presented. |
