    • A fuel cell system includes a fuel cell, a reformer, a fuel supply portion, an oxygen supply portion, a power output portion, a reformed gas supply portion, a determination portion, and a controller. The fuel cell generates electric power through a reaction of hydrogen and oxygen. The reformer generates reformed gas, including hydrogen, from an emission gas of the fuel cell and hydrocarbon fuel through a steam reforming reaction and a partial oxidation reaction. The emission gas of the fuel cell includes steam and the reformer provides the reformed gas to the fuel cell. The fuel supply portion provides the hydrocarbon fuel to the reformer. The oxygen supply portion provides oxygen-including gas to the reformer. The power output portion is activated by at least part of at least one of the reformed gas and the hydrocarbon fuel. The reformed gas supply portion provides the reformed gas to the power output portion. The determination portion determines whether an amount of steam required for the steam reforming reaction is included in the emission gas. The controller controls the oxygen supply portion and the fuel supply portion so that a rate of oxygen provided to the reformer increases as compared to a case where the reformed gas is not provided to the power output portion, if the determination portion determines that the amount of steam required for the steam reforming reaction is not included in the emission gas.
    • 燃料电池系统包括燃料电池,重整器,燃料供应部分,氧气供应部分,动力输出部分,重整气体供应部分,确定部分和控制器。 燃料电池通过氢和氧的反应产生电力。 重整器通过蒸汽重整反应和部分氧化反应从燃料电池的排放气体和烃燃料产生包括氢的重整气体。 燃料电池的排放气体包括蒸汽,重整器将重整气体提供给燃料电池。 燃料供应部分向重整器提供烃燃料。 供氧部分向重整器提供含氧气体。 功率输出部分由至少一个重整气体和烃燃料的至少一部分激活。 改质气体供给部将重整气体提供给动力输出部。 确定部分确定排放气体中是否包括蒸汽重整反应所需的蒸汽量。 控制器控制供氧部分和燃料供应部分,使得与重整气体未提供给功率输出部分的情况相比,提供给重整器的氧气的比例增加,如果确定部分确定 蒸汽重整反应所需的蒸汽不包括在排放气体中。
