Claim Text:
1. A fuel cell system comprising: a fuel cell including an anode; an aqueous solution holding device including a first storing portion and a second storing portion each arranged to hold aqueous fuel solution to be supplied to the fuel cell, and a connecting portion arranged to connect the first storing portion and the second storing portion with each other; a circulation device arranged to circulate a supply of the aqueous fuel solution between the fuel cell and the aqueous solution holding device by supplying the aqueous fuel solution from the aqueous solution holding device to the anode of the fuel cell and returning the aqueous fuel solution from the anode of the fuel cell to the aqueous solution holding device, the circulation device including a supply channel arranged to supply the aqueous fuel solution from the first storing portion to the anode of the fuel cell, a first return channel arranged to return the aqueous fuel solution from the anode of the fuel cell to the first storing portion, and a second return channel arranged to return the aqueous fuel solution from the anode of the fuel cell to the second storing portion without the aqueous fuel solution first passing through the first storing portion; a temperature detection device arranged to detect a temperature of the aqueous fuel solution; and a setting device programmed to set an amount of the aqueous fuel solution to flow through the first return channel and an amount of the aqueous fuel solution to flow through the second return channel based on a detection result from the temperature detection device; wherein the second storing portion is arranged to concurrently receive the aqueous fuel solution into the second storing portion through an input pipe of the second return channel and to discharge the aqueous fuel solution from the second storing portion through the connecting portion to the first storing portion.
