An output performance diagnosis apparatus for a fuel cell acquires, in a case where determination is made that a representative value of impedance of the fuel cell acquired during a trip of a vehicle traveling with a fuel cell as a power source is equal to or less than an impedance threshold, during the trip in which the impedance is acquired, a current-voltage characteristic of the fuel cell based on a change of an output voltage of the fuel cell after a period in which the output voltage of the fuel cell is maintained in a range equal to or higher than a lower limit voltage and equal to or lower than a voltage threshold higher than the lower limit voltage over a predetermined period or more, and calculates maximum output electric power of the fuel cell based on the acquired current-voltage characteristic.
