| 摘要 |
The present invention is constituted such that the cooling capacity of a first heat exchanger (19) for cooling reformed gas introduced into the inlet of a circulation pump (14) increases along with an increase in the output of a fuel cell (11). Thus, the present invention is given a characteristic of the inlet temperature of the circulation pump (14) being relatively high during low power generation and decreasing with an increase in the power generated and can reduce relatively the amount of volume flow during high power generation, when a large amount of reformed gas is required. As a result, the dynamic range required for the circulation pump (14) can be reduced. Furthermore, water condensation at the inlet of the circulation pump (14) can be prevented during low power generation. |
