Fuel cell vehicle and method for predicting possible running distance

A fuel cell vehicle comprises a fuel cell system (50), a fuel tank (12) which stores fuel supplied to the fuel cell system (50), and a sensor (22) which detects a remaining fuel amount in the fuel tank (12). A controller (23) of the fuel cell system (50) predicts a possible running distance of the vehicle based on an energy amount obtained by subtracting the energy required to start the fuel cell system (50) from the energy amount corresponding to the detected remaining fuel amount.
