Fuel cell system of mobility and method for controlling the same

A fuel cell system of a mobility comprising:

• a control unit configured to control a remaining current of a fuel cell to be consumed by a plurality of accessories, to select at least one accessory that is a target to consume the remaining current among the plurality of accessories depending upon a temperature condition, and to set a current consumption priority of the selected accessories based on a level of a consumable power of the selected accessories,
• wherein the control unit controls the remaining current of the fuel cell to be consumed by operation of the accessories in order of priority, starting with a highest priority, until the remaining current of the fuel cell is consumed,
• wherein the temperature condition includes a cold starting condition and a normal starting condition,
• wherein the consumable power of the accessory is determined by subtracting an output currently consumed by the accessory from a maximum consumable power of the accessory,
• wherein the control unit selects the target to consume the remaining current based on whether the temperature condition is the cold starting condition or the normal starting condition, and
• wherein the control unit sets a priority to an accessory whose consumable power is equal to or higher than a consumed current for consuming the remaining current of the fuel cell among the selected accessories.
