1. A fuel cell vehicle comprising:
a motor configured to supply driving power for driving the fuel cell vehicle;
a fuel cell and a battery configured to supply electrical power for driving the motor; and
a vehicle controller configured to:
predict a shortage of discharge power of the battery by monitoring the discharge power of the battery, and
control an operation of the fuel cell before there is the shortage of the discharge power of the battery, when the shortage of the discharge power of the battery is predicted,
wherein the vehicle controller is configured to determine a time point for instructing the operation of the fuel cell based on the following factors: 1) a time point at which the discharge power of the battery begins to decrease and 2) present maximum discharge power of the battery, when the shortage of the discharge power of the battery is predicted.
