Operation control method of fuel cell and operation control apparatus of fuel cell

An operation control method of a fuel cell, comprising:

• acquiring a startup temperature of the fuel cell;
• acquiring a present temperature of the fuel cell;
• setting a target operation point of the fuel cell identified by an output voltage value and an output current value of the fuel cell based on the startup temperature and the present temperature;
• and
• controlling at least one of a flow rate of a reaction gas supplied to the fuel cell, and an output voltage of the fuel cell so that an operation point of the fuel cell becomes the target operation point, wherein
• the target operation point is an operation point at the time of a warm-up operation, and
• the setting the target operation point includes setting the target operation point according to the present temperature and setting the output voltage value of the target operation point to a lower value as the startup temperature becomes lower and the present temperature remains the same.
