Abstract

The present invention provides a heating device with cathode oxygen depletion (COD) function for a fuel cell vehicle, in which an existing COD and a heating device for improving cold startability of the fuel cell vehicle are integrated. For this purpose, the present invention provides a heating device with COD function for a fuel cell vehicle, the heating device including: a housing having an inlet and an outlet formed on both ends thereof; a start-up heater and a shut-down heater provided in parallel on one side of the housing in a direction perpendicular to a coolant flow direction; and a plurality of heaters for heating coolant provided in parallel on the other side of the housing in a direction perpendicular to the coolant flow direction, wherein cross sections in the coolant flow direction of each of the respective heaters change periodically along the longitudinal direction of the heater so as to cause a flow disturbance.
