A method for managing an ion filter of a fuel cell vehicle includes measuring a differential pressure between ends of the ion filter, calculating a change of the differential pressure according to a coolant flow at the ion filter, and determining leakage of an ion resin or a replacement time of a cartridge using the measured differential pressure or the calculated change of the differential pressure.
