A fuel cell system includes a stack unit that generates electricity by electrochemically reacting hydrogen and air; a fuel supply unit that supplies hydrogen to the stack unit; an air supply unit that supplies air to the stack unit; and a module unit having a used gas line that exhausts used gas generated from the fuel supply unit, having a fuel supply line that supplies hydrogen provided from the fuel supply unit to the stack unit, and having an air supply line that supplies air provided from the air supply unit to the stack unit, in which the used gas line, the fuel supply line, and the air supply line are sequentially arranged and integrally modularized. Hydrogen and air each having a required temperature from the stack unit are supplied to the stack unit, thereby improving thermal efficiency of the fuel cell system.
