PURPOSE: To provide a fuel cell system that is compactly designed without a pump for circulating cooling water, and has a small energy loss. CONSTITUTION: A fuel cell 12 and a radiator 15 constitute a closed loop connected by an inlet cooling tube 13 and outlet cooling tube 14 with the radiator 15 arranged in a place contacting the open air. Thus, the fuel cell 12 discharges the expanded cooling water transferred through the outlet cooling tube 14 to the radiator 15 during generation, while the radiator 15 transfers the condensed cooling water cooled by heat exchange with the open air through the inlet cooling tube 13 to the fuel cell 12. |
