Document Type and Number:
Japanese Patent JP4332185
Kind Code:
B2
Abstract:
To provide a humidification control technology for appropriately controlling a humidification amount of supply gas.
The humidification amount W is not controlled based only on a supply oxidizing gas temperature TI2after passing through a humidifier but controlled in consideration of external conditions such as the flow rate Q of the supply oxidizing gas. Specifically, the control target temperature TIWof the supply oxidizing gas after passing through the humidifier is determined to obtain the humidification amount corresponding to a request. In determining such a control target temperature TIW, the external conditions such as the flow rate Q of the supply oxidizing gas is taken into consideration, and the flow rate of oxidizing off gas led into the humidifier 120 is regulated using a by-pass valve 160 so that the supply oxidizing gas temperature TI2after passing through the humidifier, detected by a temperature sensor 24 coincides with the control target temperature TIW.
