1. A fuel cell system comprising:

  • a fuel cell configured to operate in an operation mode selected from a power generation mode and a power generation stop mode;

    a coolant supply device for circulating an amount of coolant through a coolant path for cooling the fuel cell;

    a fuel cell temperature detector for detecting a fuel cell temperature of the fuel cell;

    a coolant temperature detector for detecting a coolant temperature of the coolant in the coolant path; and

    a controller for controlling the amount of coolant circulated by the coolant supply device, selecting the operation mode of the fuel cell between the power generation mode and the power generation stop mode, and calculating the difference between the detected coolant temperature and detected fuel cell temperature;

    wherein while the operation mode of the fuel cell is selected to be the power generation stop mode the controller increases the amount of the coolant circulated as the difference between the detected coolant temperature and the detected fuel cell temperature increases.
