Zusammenfassung:	Disclosed are a method and a system for controlling a plurality of fuel cells of a fuel cell vehicle. The method comprises the steps of: increasing the power generation output of a plurality of fuel cells based on the charge amount of a high-voltage battery in a controller; deriving the deterioration rate of each fuel cell based on an output voltage compared to the consumption current of each fuel cell while increasing the power generation output of the plurality of fuel cells in the controller; and differentially controlling the power generation output of each fuel cell during the next drive of a fuel cell vehicle according to the deterioration rate derived from the controller. The present invention can evenly manage the deterioration rate of the plurality of fuel cells. 제어기에서 고전압 배터리의 충전량에 기반하여 복수의 연료전지의 발전출력을 증대시키는 단계, 제어기에서 복수의 연료전지의 발전출력을 증대시킨 상태에서, 각 연료전지의 소모전류 대비 출력전압에 기반하여 각 연료전지의 열화도 비율을 도출하는 단계 및 제어기에서 도출된 열화도 비율에 따라 연료전지 차량의 차기 주행시 각 연료전지의 발전출력을 차등 제어하는 단계를 포함하는 연료전지 차량의 복수의 연료전지 제어방법 및 그 제어시스템이 소개된다.
