摘要
燃料电池具有能量转化效率高、低噪声、低排放、稳定可靠等优点,被认为是继蒸汽机和内燃机之后的第三代动力系统。燃料电池已经成为无人机、轻型飞机的主动力,并用于大型客机的辅助动力装置。本文设计了应用质子交换膜燃料电池直接驱动直流电机和螺旋桨的方案,并利用Matlab/Simulink构建了仿真模型,模拟燃料电池的动态输出特性以及电动机的转速特性。该模型可以为燃料电池飞行器的研发提供参考数据。
Fuel cell is believed to be the third generation power system after the steamer and the internal-combustion engine, with the virtues of high efficiency, low noise, low emission, reliability and stability. Fuel cell have been developed as the main power of UAV and light airplane, or as the APU of a large passenger airliner. In this paper, a DC motor system is proposed, which is driven directly by a Proton Exchange Membrane fuel cell. A Matlab/Simulink model is used to simulate the dynamic characteristics of the fuel cell and the motor speed. The work here can be applied to help the design of the fuel cell powered flight vehicles.
