ABSTRACT:
A fuel cell system and related operating method are disclosed wherein a water storage section (a water storage tank33), that stores water to humidify a fuel cell1, is provided with a heat transfer surface (52ato55a, 52bto54b) that is heated by hot medium supplied to a hot medium flow passage. The heat transfer surface is inclined such that a surface area surrounded by the heat transfer surface increases as a water level increases. Antifreeze solution forming coolant medium of the fuel cell is heated and used as hot medium of the hot medium flow passage.
