| Zusammenfassung: | To provide a fuel circuit of the fuel cell system, wherein a fuel pump is possibly scaled down while power consumption is also possibly controlled, along with this, required amount of fuel circulation is securable in the time of the output change in a fuel cell, comprising fuel cell 1 which generates electricity by being supplied with fuel and an oxidant; fuel supply stream passage 7 for sending the fuel to the fuel cell 1; fuel circuit stream passage 6 for making the unconsumed fuel discharged from the fuel cell 1 merge with the fuel supply stream passage 7 to be recirculated; the fuel pump (hydrogen pump 5) which takes in and sends out the unreacted fuel; and ejector 2 which inhales the unreacted fuel using the negative pressure generated when the fuel flows, the unreacted fuel being made to be merged with the fuel supplied to the fuel cell 1 thereafter. |
