難である等の問題点があつた。Since the conventional fuel cell water treatment system is configured as described above, the cell cooling water quality deteriorates until the level of the stagnant water in the steam separator (3) drops to the ON level of the makeup water pump (14), Since the water quality is improved only after the make-up water pump (14) supplies high-purity pure water, the fluctuation of the water quality is large, and it is necessary to achieve the water quality standard by using a relatively large amount of blow water. (14) The power was large. Further, the fuel cell (6) needs to circulate hot water to keep the battery warm even during shutdown. However, since the pressure in the steam separator (3) is low, it is difficult to discharge blow water and maintain water quality. There were problems such as difficulty.
