Disclosed are a hydrogen fuel cell vehicle including a direct current converter flexibly operating according to the real-time voltage of a fuel cell, and a control method therefor, the hydrogen fuel cell vehicle comprising a fuel cell DC-DC converter (FDC) which is disposed between a fuel cell and a driving battery so as to be connected to each of the fuel cell and the driving battery to enable electrical conduction therebetween, and which controls power transmission between the fuel cell and the driving battery, wherein the FDC compares the magnitude of the voltage of the fuel cell and a preset target voltage to determine, on the basis of the comparison, a power transmission direction and whether power is transmitted between the voltage of the fuel cell and the driving battery, and thus the voltage of the fuel cell is adjusted to be equal to the preset target voltage.

    L'invention concerne un véhicule à pile à combustible à hydrogène comprenant un convertisseur de courant continu fonctionnant de manière flexible en fonction de la tension en temps réel d'une pile à combustible, ainsi qu'un procédé de commande associé, le véhicule à pile à combustible à hydrogène comprenant un convertisseur CC-CC de pile à combustible qui est agencé entre une pile à combustible et une batterie d'entraînement de manière à être connectée à chacune de la pile à combustible et de la batterie d'entraînement pour permettre une conduction électrique entre celles-ci et qui commande la transmission de puissance entre la pile à combustible et la batterie d'entraînement, le convertisseur de pile à combustible comparant l'amplitude de la tension de la pile à combustible et une tension cible prédéfinie pour déterminer, sur la base de la comparaison, une direction de transmission de puissance et si la puissance est transmise entre la tension de la pile à combustible et la batterie d'entraînement. Ainsi la tension de la pile à combustible est réglée pour être égale à la tension cible prédéfinie.

    본 발명은, 연료 전지의 실시간 전압에 따라 유동적으로 가동되는 직류 컨버터를 포함하는 수소 연료 전지 차량 및 이의 제어 방법에 있어서, 연료 전지 및 구동용 배터리 사이에 배치되어, 상기 연료 전지 및 상기 구동용 배터리와 각각 통전 가능하게 연결되고, 상기 연료 전지와 상기 구동용 배터리 간 송전을 제어하는 FDC(Fuel Cell DC-DC Converter, 연료 전지 직류 컨버터)를 포함하고, 상기 FDC는, 상기 연료 전지의 전압과 기 설정된 목표 전압의 대소를 비교하여 이를 토대로 상기 연료 전지의 전압과 상기 구동용 배터리 간 송전 여부 및 송전 방향을 결정함으로써 상기 연료 전지의 전압이 상기 기 설정된 목표 전압과 동일해지도록 조절하는, 수소 연료 전지 차량 및 이의 제어 방법을 개시한다.
