Produced water W is collected from fuel cell 24 and supplied to produced water collection chamber 22. This collected produced water W and fuel F are supplied to mixing chamber 23 via flow rate adjusting nozzles 25, 26 controlled by control signals g and h. They are mixed at a mixture ratio in accordance with the amount of power consumed by mobile telephone 40 and supplied to fuel cell 24. Thus, produced water W is reused to produce a mixed fuel. Accordingly, when mobile telephone 40 using fuel cell 24 is kept in the clothing or in the bag of a user, there is no need for discharging produced water W to the outside. Moreover, since the mixed fuel is produced at the mixture ratio in accordance with the amount of power consumed by mobile telephone 40, with the result that the amount of power generated by fuel cell 24 is adjusted, no unnecessary power is generated and heating can be suppressed even when the functions used in mobile telephone 40 are changed. Thus, it is possible to improve the efficiency and safety of the fuel cell device and user-friendliness of a mobile electronic device that uses the fuel cell device.
