PURPOSE:To simplify a control system by setting a process which controls air to primary setting temperature by heat exchange with steam and a process which controls the air and fuel to each setting temperature by heat exchange of the air with fuel. CONSTITUTION:Temperature of air which its flow rate is controlled with a controller 13 is detected with a temperature sensor 21 before the air enters a fuel cell 11, and a steam flow rate is controlled with a steam flow rate control valve 22. The steam is introduced to a primary heat exchanger 25 and heat-exchanged with the air which its flow rate is controlled to obtain the air having primary setting temperature which is higher than final temperature. The air is introduced to a final heat exchanger 26 and heat-exchanged with the fuel which its flow rate is controlled with a controller 12. The air and fuel which are controlled to a specified temperature are supplied to a fuel cell 11. Since temperature control of only either one of air and fuel is required, a control system in simplified. |
