Introduced are a method and system for controlling regenerative braking of a fuel cell vehicle. The method for controlling regenerative braking of a fuel cell vehicle includes the steps of: blocking an air flow into a fuel cell at the time of entering the regenerative braking; charging a high voltage battery with regenerative braking energy; connecting a COD heater to a high voltage line when the high voltage battery is fully charged; and regulating the voltage of the high voltage line through a DC-DC converter according to the regenerative braking energy. Accordingly, the present invention can improve driving stability and prevent high voltage battery energy waste.
