APPARATUS FOR CONTROLLING FUEL CELL SYSTEM AND METHOD THEREOF

An apparatus for controlling a cold start and a cold shutdown (CSD) of a fuel cell system and a method thereof are provided. A monitoring device may individually monitor at least one of an amount of accumulated power and/or an accumulated driving time of one or more fuel cell stacks. A controller may select a representative fuel cell stack among the one or more fuel cell stacks, based on the amount of accumulated power and/or the amount of accumulated driving time, performs a cold start of the representative fuel cell stack, and perform cold starts of the remaining fuel cell stacks, using power of the representative fuel cell stack after the cold start of the selected representative fuel cell stack is completed. The apparatus makes power used for a cold start and a CSD highly efficient.
