Fuel Cell System and Method of Controlling the Same

原文（中文）

Disclosed are a fuel cell system and control method thereof, the fuel cell system comprising a fuel cell stack including a plurality of cells, and a controller that controls an output of the stack based on an available lower limit voltage of the stack, and adjust the available lower limit voltage of the stack by reflecting at least one of a first margin according to a cell voltage ratio and a second margin according to an available output of a provided battery when the cell voltage ratio, which is a ratio of a minimum cell voltage and an average cell voltage for the stack, is less than a preset reference cell voltage ratio.
