摘要： A fuel cell system increases an output voltage of a fuel cell if an electric power generation command value Pref for the fuel cell abruptly reduces while the fuel cell is being warmed up at a low-efficiency operation, which has lower electric power generation efficiency than that of a normal operation. Thus, the surplus electric power Ws corresponding to the difference between an electric power generation amount Pmes of the fuel cell and the electric power generation command value Pref is stored into a capacitive component of the fuel cell, thereby matching the electric power supplied to an external load of the fuel cell (Pmes-Ws) with the electric power generation command value Pref. This makes it possible to conduct control not to supply the surplus electric power to the external load when the electric power required from the fuel cell suddenly reduces during the low-efficiency operation.
摘要翻译：如果燃料电池的发电指令值Pref在燃料电池处于低效率运行时被加热的情况下，燃料电池的发电指令值Pref突然降低，则燃料电池系统增加燃料电池的输出电压，其发电效率比其低的正常操作。因此，对应于燃料电池的发电量Pmes与发电指令值Pref的差的剩余电力Ws被存储在燃料电池的电容部件中，从而将供给到外部的电力的电力具有发电指令值Pref的燃料电池（Pmes-Ws）的负载。这使得当在低效率操作期间当燃料电池所需的电力突然降低时，可以进行不向外部负载供应剩余电力的控制。
