PURPOSE:To maintain an appropriate temperature range during operation even in an operation condition or operation environment where cell temperature might increase above the appropriate temperature due to heat generation of the cell by evaporating water in anolyte whereby latent heat of evaporation cools the anolyte. CONSTITUTION:Air, fed by an air supplier 7 such as fan through a valve 18, is in contact with an anolyte in a cooler 2 utilizing evaporation latent heat provided on an anolyte circulation flow route 11. Then, being cooled by the latent heat of water evaporation, the anolyte returns to an anolyte circulation bath 3 and the moistened air is discharged out of the system. By the arrangement, since the anolyte with low temperature circulates inside the fuel cell body 1, an appropriate temperature range of the cell temperature is maintained and stable operation can be continued. |
