Abstract:
1. A fuel cell device comprising: a fuel cell cooled by antifreeze solution; a water storage unit adapted to store water to be supplied to the fuel cell; a radiator adapted to cool the antifreeze solution that cooled the fuel cell; an antifreeze heater disposed in an antifreeze circulation flow passage to heat the antifreeze solution; a first antifreeze circulation flow passage adapted to circulate the antifreeze solution through the fuel cell and the radiator; a second antifreeze circulation flow passage adapted to circulate the antifreeze solution through the fuel cell, the water storage unit and the antifreeze heater, by bypassing the radiator; and a hot medium flow passage disposed around and conforming, in a contacting relationship, to a water contact section on an outside of the water storage unit to allow the antifreeze solution, heated by the antifreeze heater, to flow around the outside of the water storage unit.
