Output performance recovering device for fuel cell and output performance recovering method for fuel cell

An output performance recovering device for a fuel cell, comprising:

• a recovery unit programmed:
• to control a voltage of the fuel cell which is mounted as a power source for traveling in a vehicle and to perform recovery processing for recovering a catalyst of the fuel cell from short-term performance deterioration,
• not to perform the recovery processing when it is not necessary to recover the catalyst from the short-term performance deterioration,
• to perform the recovery processing when it is necessary to recover the catalyst from the short-term performance deterioration and a parameter correlated with a predicted output value of the fuel cell, which has been predicted to be output on a scheduled traveling route of the vehicle and which has been calculated based on a predicted vehicle speed of the vehicle on the scheduled traveling route, indicates that the predicted output value is greater than a first threshold value,
• not to perform the recovery processing when the parameter indicates that the predicted output value is less than the first threshold value even if it is necessary to recover the catalyst from the short-term performance deterioration, and
• to calculate the predicted vehicle speed based on an average vehicle speed which is an average value of traveling speeds of a vehicle group including or not including the vehicle when the vehicle group travels on the scheduled traveling route;
• an acquisition unit programmed to acquire the predicted vehicle speed or the average vehicle speed from a server;
• an upper-limit output changing unit programmed to change an upper limit of an output of the fuel cell;
• and
• a state-of-charge changing unit programmed to change a target state of charge of a secondary battery that compensates for a shortage of an output of the fuel cell.
