1. A system for controlling electric power of a vehicle having a fuel cell, comprising:
a fuel cell configured to generate electric energy by receiving fuel and oxidizing gas;
a battery configured to receive the electric energy of the fuel cell to charge or discharge the battery for supplying the electric energy;
a sensor configured to sense a driving state of the vehicle; and
a controller configured to control charging or discharging of the battery based on the driving state sensed by the sensor;
wherein the controller is configured to set a target state of charge of the battery based on the sensed driving state and control charging or discharging of the battery to correspond to the set target state of charge; and
wherein the controller is configured to continuously increase or decrease the target state of charge in response to the sensor sensing that the vehicle continuously performs uphill driving or downhill driving.
