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.

    회생제동 진입시 연료전지에의 공기유입을 차단하는 단계; 회생제동 에너지를 고전압배터리로 충전하는 단계; 고전압배터리가 만충 상태인 경우 COD히터를 고전압라인에 연결하는 단계; 및 회생제동 에너지에 따라 DC-DC컨버터를 통해 고전압라인의 전압을 제어하는 단계;를 포함하는 연료전지차량의 회생제동 제어방법 및 제어시스템이 소개된다.
