Disclosed is a fuel cell system and a draining method for the same based on the use of a reformer, a fuel cell, a methanol tank for storing methanol, a water recovery tank for storing water discharged, for example, from the fuel cell, an aqueous methanol solution tank for mixing methanol and water, and a changeover valve connected under the water recovery tank and capable of draining all of water contained in the water recovery tank and a water passage. Accordingly, no water remains and freezes in the fuel cell system when the system is stopped. It is possible to reliably start the system, and it is possible to improve the reliability.
