1. A power generation stopping method for a fuel cell system including a fuel cell, comprising:

  • continuing generating electric power by the fuel cell via electrochemical reaction between fuel gas and oxidant gas during a post running period after the fuel cell system is ordered to stop;

    supplying a coolant at a first flow rate to the fuel cell during the post running period until temperature of the fuel cell reaches a threshold temperature; and

    supplying a coolant to the fuel cell at a second flow rate larger than the first flow rate during the post running period after the temperature of the fuel cell has reached the threshold temperature.
