Fuel cell system |
摘要 |
Provided is a fuel-cell system having a control device which controls driving of a first fuel supply device and a second fuel supply device. The control device includes, a driving-interval setting unit which sets first driving intervals for the first fuel supply device and second driving intervals for the second fuel supply device, a first fuel-supply-device control unit which sets valve-open durations of the first fuel supply device according to the first driving intervals, and a second fuel-supply-device control unit which sets valve-open durations of the second fuel supply device according to the second driving intervals. The driving-interval setting unit sets the second driving intervals to be shorter than the first driving intervals. |

1. A fuel-cell system comprising:
a fuel cell which is supplied with a fuel gas and an oxidant gas to generate electric power; fuel-gas supply piping which connects the fuel cell and a fuel tank; fuel-off-gas exhaust piping into which a fuel off-gas exhausted from the fuel cell flows; fuel-gas circulation piping which connects the fuel-off-gas exhaust piping and the fuel-gas supply piping; a first injector which is arranged in the fuel-gas supply piping on an upstream side of a connection between the fuel-gas supply piping and the fuel-gas circulation piping; bypass piping which branches off from the fuel-gas supply piping, forms a bypass of the first injector and the connection, and joins the fuel-gas supply piping; a second injector arranged in the bypass piping; and a control device which controls driving of the first injector and the second injector, and is programmed at least to set first driving intervals for the first injector and second driving intervals for the second injector, set valve-open durations of the first injector according to the first driving intervals, and set valve-open durations of the second injector according to the second driving intervals, wherein the second driving intervals are set to be shorter than the first driving intervals. |
