    • A fuel cell system includes a stack; an antifreezing heater; a surplus power heater; a switching unit; and an electric power conversion unit. Where a first supply path denotes a power supply path from a system power supply to the antifreezing heater, a second supply path denotes a power supply path from the stack to the antifreezing heater, and a third supply path denotes a power supply path from the stack to the surplus power heater, when a power failure happens, the switching unit disconnects the first supply path, disconnects the second supply path and connects the third supply path until an output electric power of the stack is converted to the power necessary for operating the antifreezing heater, and connects the second supply path and disconnects the third supply path after the output power of the stack is converted to the power necessary for operating the antifreezing heater.
    • 燃料电池系统包括: 防冻加热器 剩余电力加热器; 开关单元; 和电力转换单元。 在第一供给路径表示从系统电源向防冻加热器的供电路径的情况下,第二供给路径表示从堆叠到防冻加热器的供电路径,第三供给路径表示从堆叠 对于剩余电力加热器,当发生电力故障时,开关单元断开第一供应路径,断开第二供应路径并连接第三供应路径,直到堆叠的输出电力转换为运行防冻为目的所需的电力 加热器,并且在堆叠的输出功率被转换为操作防冻加热器所需的电力之后,连接第二供应路径并断开第三供应路径。
