A fuel cell system is provided to obtain a structure capable of humidifying and heating air introduced into an air electrode of a stack unit at once, save a production cost, and to be reduced in size. A fuel cell system includes: a stack unit(130) which generates electricity by an electrochemical reaction of hydrogen and air; a fuel supply unit(110) which supplies hydrogen to the stack unit; an air supply unit(120) which supplies air to the stack unit; and a cooling unit(150) having a cooling tank(151) in which coolant for cooling the stack unit is stored, and a coolant circulation line(Lc) which enables the stored coolant to be circulated to the inside of the stack unit. Air to be supplied from the air supply unit to the stack unit is heated and humidified while passing over coolant stored in the cooling tank. |
