The present invention discloses a hydrogen supply device of a fuel cell vehicle and a controlling method thereof. The hydrogen supply device of a fuel cell vehicle according to the present invention comprises: container valves respectively mounted on a plurality of hydrogen containers, and supplying and blocking hydrogen; a manifold connected to the plurality of hydrogen containers by a supply pipe; a regulator connected to the manifold and supplying high-pressure hydrogen at a reduced pressure required for a fuel cell; a supply valve installed on the supply pipe between the manifold and the regulator, and regulating hydrogen supply; a pressure sensor for detecting the pressure of the manifold; and a control part for supplying hydrogen by actuating the container valves and the supply valve after performing an initial operation sequence when a start-on signal is input from a peripheral control device. Therefore, provided are a hydrogen supply device of a fuel cell vehicle and a controlling method thereof, wherein hydrogen is supplied to a fuel cell after an initial operation sequence is performed during the start of a fuel cell vehicle to detect and stabilize a pressure change caused by a pressure difference for each container.

    본 발명은 연료전지 차량의 수소 공급장치 및 그 제어방법이 개시된다. 본 발명의 연료전지 차량의 수소 공급장치는, 다수개의 수소용기에 각각 장착되어 수소를 공급하고 차단하는 용기밸브; 다수개의 수소용기와 공급배관으로 연결되는 매니폴드; 매니폴드와 연결되어 고압의 수소를 연료전지에 필요한 압력으로 낮추어 공급하는 레귤레이터; 매니폴드와 레귤레이터 사이의 공급배관에 설치되어 수소공급을 단속하는 공급밸브; 매니폴드의 압력을 감지하는 압력센서; 및 주변제어장치로부터 시동 온신호가 입력되면 초기 구동시퀀스를 수행한 후 용기밸브와 공급밸브를 작동시켜 수소를 공급하는 제어부;를 포함하는 것을 특징으로 한다.
