Abstract
There is disclosed a fuel cell system including a fuel cell, a fuel supply system to supply a fuel gas to the fuel cell, an injector which adjusts a gas state on an upstream side of the fuel supply system to supply the gas to a downstream side, and a control unit which drives and controls the injector in a predetermined drive cycle. The control unit sets the drive cycle of the injector in accordance with an operation state of the fuel cell.

2. A fuel cell system comprising:
- a fuel cell;
a fuel supply system to supply a fuel gas to this fuel cell;
an injector which adjusts a gas state on an upstream side of this fuel supply system to supply the gas to a downstream side; and
a control device for driving and controlling this injector in a predetermined drive cycle,wherein the control device sets the drive cycle to be long when an amount of a power generated by the fuel cell is small. - View Dependent Claims (7, 8)

3. A fuel cell system comprising:
- a fuel cell;
a fuel supply system to supply a fuel gas to this fuel cell;
an injector which adjusts a gas state on an upstream side of this fuel supply system to supply the gas to a downstream side; and
a control device for driving and controlling this injector in a predetermined drive cycle,wherein the control device sets the drive cycle to be long when a pressure of the fuel gas supplied to the fuel cell is low.

4. A fuel cell system comprising:
- a fuel cell;
a fuel supply system to supply a fuel gas to this fuel cell;
an injector which adjusts a gas state on an upstream side of this fuel supply system to supply the gas to a downstream side; and
a control device for driving and controlling this injector in a predetermined drive cycle,wherein the fuel supply system has a fuel supply channel to supply, to the fuel cell, the fuel gas supplied from the fuel supply system, a fuel discharge channel to discharge a fuel off gas coming from the fuel cell and a discharge valve to discharge the gas from the fuel discharge channel, and the control device controls an opening/closing operation of the discharge valve to execute a purge operation of the fuel off gas, and sets the drive cycle during the execution of the purge operation to a shorter time than during the execution of no purge operation.

5. A fuel cell system comprising:
- a fuel cell;
a fuel supply system to supply a fuel gas to this fuel cell;
an injector which adjusts a gas state on an upstream side of this fuel supply system to supply the gas to a downstream side; and
a control device for driving and controlling this injector in a predetermined drive cycle,wherein the control device performs calculation in a predetermined calculation period, and sets the drive cycle to a multiple number of the calculation period.

6. A fuel cell system comprising:
- a fuel cell;
a fuel supply system to supply a fuel gas to this fuel cell;
an injector which adjusts a gas state on an upstream side of this fuel supply system to supply the gas to a downstream side; and
a control device for driving and controlling this injector in a predetermined drive cycle,wherein the control device sets the drive cycle during totally opening control or totally closing control of the injector to a shorter time than during non-totally opening control or non-totally closing control.
- a fuel cell;
