A fuel cell power system and a method of starting a fuel cell power system. The fuel cell power system includes: a fuel cell system having one or more voltage outputs; one or more DC/DC converters each having an output terminal and an input terminal connectable to a voltage output terminal of the fuel cell system; a DC voltage link connectable to an output of the one or more DC/DC converters; and a local load connectable to the DC voltage link. In the system, a local load is adapted to draw power from the fuel cell system to reduce the voltage of the fuel cell system. 燃料电池电力系统以及启动燃料电池电力系统的方法。该燃料电池电力系统包括：燃料电池系统，其具有一个或更多个电压输出端；一个或更多个DC/DC转换器，各自具有输出端和输入端，所述输入端可连接至燃料电池系统的电压输出端；DC电压链路，其可连接至一个或更多个DC/DC转换器的输出端；以及局部负载，其可连接至DC电压链路。在该系统中，局部负载适于从燃料电池系统中汲取电力以降低燃料电池系统的电压。
