    • A method of operating a fuel cell assembly and a fuel cell system use a simple construction to restrain deterioration of power generating performance of a fuel cell assembly at a startup in a subfreezing environment. If an ignition switch is turned off is STEP 1, a control unit determines in STEP 3 whether the temperature of a fuel cell assembly (the internal temperature of the fuel cell assembly) is lower than a predetermined temperature, which is higher than the temperature at which the water produced during power generation freezes. If the internal temperature of the fuel cell assembly is the predetermined temperature or higher, then the processing proceeds to STEP 4 wherein a power generating condition is adjusted to cause the internal temperature of the fuel cell assembly to rise. In STEP 5, an alarm device is actuated. The power generation is continued until the internal temperature of the fuel cell assembly reaches the predetermined temperature or higher, and then the power generation is stopped in STEP 8.
    • 操作燃料电池组件和燃料电池系统的方法使用简单的结构来抑制燃料电池组件在低温环境中的启动时的发电性能的劣化。 如果点火开关关闭是步骤1,则控制单元在步骤3中确定燃料电池组件的温度(燃料电池组件的内部温度)是否低于预定温度,该预定温度高于 发电时产生的水冻结。 如果燃料电池组件的内部温度为预定温度或更高,则处理进行到步骤4,其中调节发电状态以使燃料电池组件的内部温度升高。 在步骤5中,启动报警装置。 继续发电直到燃料电池组件的内部温度达到预定温度或更高,然后在步骤8中停止发电。
