Abstract: A fuel cell system capable of preventing the decrease in the amount of coolant is provided. The fuel cell system is provided with: a power generation portion; a coolant flow passage through which a coolant flows that cools the power generation portion; a tank disposed on the coolant flow passage in a position below the power generation portion in the vertical direction and storing the coolant; an air flow passage connecting the uppermost part of the coolant flow passage in the vertical direction and the tank; and an on-off valve provided on the air flow passage. By the on-off valve being opened, the air in the tank is introduced into the coolant flow passage through the air flow passage, and the coolant in the coolant flow passage is introduced into the tank. Since the coolant flow passage never communicates with the atmosphere, the vaporized coolant is prevented from being released to the atmosphere, so that the decrease in the amount of coolant can be prevented.
