FUEL CELL SYSTEM AND METHOD OF CONTROLLING FUEL CELL SYSTEM

A fuel cell system and a method of controlling the same are presented. The fuel cell system includes: a hydrogen gas supply unit connected to a hydrogen gas inlet side of a fuel cell stack, in which a supply valve and a sensor are provided; a hydrogen discharge unit connected to a hydrogen outlet side of the fuel cell stack, in which a water collector and a purge valve are disposed; and a controller configured to calculate an amount of hydrogen discharged through the purge valve from an amount of hydrogen supplied to the fuel cell stack and an amount of hydrogen consumed therein, and perform compensation control of the supply valve when the amount of hydrogen discharged is at or higher than a reference value. 提出了一种燃料电池系统及控制燃料电池系统的方法。该燃料电池系统包括：氢气供应单元，连接到燃料电池堆的氢气入口侧，在氢气供应单元中设置有供应阀和传感器；氢气排放单元，连接到燃料电池堆的氢气出口侧，在氢气排放单元中设置有集水器和净化阀；以及控制器，被配置为从供应到燃料电池堆的氢气的量和其中消耗的氢气的量计算通过净化阀排放的氢气的量，并且当排放的氢气的量处于或高于参考值时执行供应阀的补偿控制。
