Fuel cell system

A fuel cell system, comprising:

• a fuel cell stack;
• a first injector and a second injector different from the first injector, each configured to supply fuel gas to the fuel cell stack;
• and
• a controller configured to control injection of the fuel gas by the first injector and the second injector, wherein
• the controller:
• counts an injection count of the second injector;
• when the injection count of the second injector is less than a second predetermined number smaller than a first predetermined number predetermined as an upper limit count, performs a normal control in which an injection control is performed using the first injector and the second injector in a case where a required power generation amount required for the fuel cell system is equal to or less than a first output value, and the injection control is performed using the second injector in a case where the required power generation amount exceeds the first output value;
• and
• when the injection count of the second injector is equal to or greater than the second predetermined number, performs a durability adjustment control in which the injection control is performed using the first injector in a case where the required power generation amount is equal to or less than a second output value corresponding to a maximum injection amount of the first injector.
