The invention discloses a power supply device for a fuel cell and a power supply method thereof. The power supply device is arranged on an aircraft. The power supply device comprises a secondary battery, a transformer, a fuel cell and a bypass switch. The transformer is electrically connected between the secondary battery and the aircraft. The fuel cell is electrically connected to the aircraft and is adapted to provide a first output current to the aircraft. The bypass switch is electrically connected between one output end of the secondary battery and one output end of the fuel battery, and the bypass switch is connected with the transformer in parallel. The transformer has a first output voltage set value. When a first output end voltage of the fuel cell is lower than the first output voltage set value, and the bypass switch is in a non-conducting state, a second output current of the secondary battery is provided for the aircraft through the transformer; when the first output end voltage of the fuel cell is lower than the first output voltage set value, and the bypass switch is in an on state, the second output current of the secondary battery is provided for the aircraft through the bypass switch.

    一种用于燃料电池的供电装置及其供电方法。供电装置配置于一飞行器上。供电装置包括一二次电池、一变压器、一燃料电池以及一旁路开关。变压器电性连接于二次电池与飞行器之间。燃料电池电性连接于飞行器,且适于提供一第一输出电流给飞行器。旁路开关电性连接于二次电池的一输出端与燃料电池的一输出端之间,且旁路开关与变压器并联。变压器具有一第一输出电压设定值。当燃料电池的一第一输出端电压低于该第一输出电压设定值时,且旁路开关处于不导通状态,二次电池的一第二输出电流经由变压器提供给飞行器;当该燃料电池的该第一输出端电压低于该第一输出电压设定值时,且旁路开关处于导通状态,该二次电池的第二输出电流经由旁路开关提供给飞行器。
