The present invention relates to a technology for preventing damage to a relay, minimizing hydrogen loss, and preventing shutdown time delay when a fuel cell vehicle stops driving. In the present invention, a method for stopping driving a fuel cell vehicle is introduced, which blocks supply of air to a fuel cell stack when an operation stop command of the fuel cell vehicle is applied, increases and controls a voltage at a rear end of the stack main relay connected to the fuel cell stack, and blocks the stack main relay when the voltage of the rear end of the stack main relay rises above the stack voltage by a predetermined voltage.

    본 발명은 연료전지 차량의 운전 정지시 릴레이의 손상을 방지하고, 수소의 손실을 최소화하고, 셧다운 시간 지연을 방지하는 기술에 관한 것으로, 본 발명에서는, 연료전지 차량의 운전 정지명령 인가시, 연료전지 스택에 공기의 공급을 차단하고; 연료전지 스택과 연결된 스택 메인릴레이 후단의 전압을 상승 제어하며; 상기 스택 메인릴레이 후단의 전압이 스택전압보다 소정전압 이상 상승하는 경우, 스택 메인릴레이를 차단하는 것을 특징으로 하는 연료전지 차량용 운전 정지방법이 소개된다.
