Abstract
A fuel cell system includes a fuel cell stack and a humidifier. The humidifier includes an unreacted gas inlet port connected to an end of an unreacted hydrogen discharge pipeline, which is connected at the other end to a hydrogen outlet port of the fuel cell stack, such that the unreacted hydrogen discharged from the fuel cell stack via the hydrogen outlet port is led by the unreacted hydrogen discharge pipeline into the humidifier. The humidifier regulates the humidity and concentration of the unreacted hydrogen led thereinto, and the unreacted hydrogen is then discharged from the humidifier.
