A power supply device disposed on an aircraft to provide a power to the aircraft is provided. The aircraft has an average required power value. The power supply device includes a secondary battery, atransformer and a fuel cell. The transformer is coupled between the secondary battery and the aircraft. The fuel cell is coupled to the aircraft and is adapted to provide a first output current to theaircraft. The transformer has an output voltage set value. When the first output end voltage of the fuel cell is lower than the output voltage set value, the transformer provides a second output current of the secondary battery to the aircraft. The output voltage set value is in a voltage range with a fuel cell output power between the maximum power value of characteristic curve of the fuel celland the average required power value of the aircraft. 供电装置配置于飞行器上，以供电给飞行器。飞行器具有平均所需功率值。供电装置包括二次电池、变压器及燃料电池。变压器耦接于二次电池与飞行器之间。燃料电池耦接于飞行器且适于提供第一输出电流给飞行器。变压器具有输出电压设定值。当燃料电池的第一输出端电压低于输出电压设定值时，变压器将二次电池的第二输出电流提供给飞行器。输出电压设定值介于燃料电池的特性曲线
