Abstract
A fuel cell system including a flat type stack in which a plurality of unit cells, in which an electricity generating reaction is performed, are arranged on a plane, and the fuel cell system pre-heats the fuel provided from the outside for reducing the temperature differences of the fuel provided to each unit cell, thereby reduces the differences in the output characteristics of each unit cell, thereby increasing the electricity generating efficiency of the system.
