Output prediction device for fuel cell, output prediction method for fuel cell and fuel cell system

An output prediction device for a fuel cell comprising:

• a first acquisition circuitry configured to acquire a first required output of the fuel cell, the first required output being calculated based on predicted vehicle speeds or predicted accelerations of multiple vehicles including a vehicle traveling by using the fuel cell as a dynamic power source, the multiple vehicles traveling on a scheduled traveling route for the vehicle traveling by using the fuel cell;
• a second acquisition circuitry configured to acquire a second required output of the fuel cell, the second required output being required by an air-conditioning device of the vehicle;
• and
• a calculation circuitry configured to calculate a parameter correlated with a predicted output value of the fuel cell, based on the first required output and the second required output, the predicted output value being predicted as an output on the scheduled traveling route.
