ABSTRACT:
A fuel cell system includes a branch anode gas supply pipe in which hydrogen before supplied to a fuel cell flows; and a branch cathode gas supply pipe in which air before supplied to the fuel cell flows. One end on the upstream side of the branch anode gas supply pipe is connected to the upstream side of a regulator in an anode gas supply pipe, and the other end thereof is connected to the branch cathode gas supply pipe via a hydrogen injector. The branch anode gas supply pipe is provided with a hydrogen regulator, which detects a pressure in the branch cathode gas supply pipe as a signal pressure.
