To provide a configuration such that cooling capacity of a first heat exchanger (19) for cooling a reformed gas introduced into an inlet of a circulation pump (14) is increased as an output of a fuel cell (11) increases. With this configuration, a characteristic is provided such that an inlet temperature of the circulation pump (14) is relatively high during low power generation and decreases as the generation power increases, and a volumetric flow rate during high power generation in which a large amount of reformed gas is required can be decreased relatively. As the result, a dynamic range required for the circulation pump (14) can be made small. Furthermore, water condensation in the inlet of the circulation pump (14) can be prevented during low power generation. |
