Embodiment 1
[0037] FIG. 1 is an external view of a fuel cell device of the present invention mounted on a load, and FIG. 2 is a block diagram of the fuel cell device. In this embodiment, since the fuel cartridges 10a, 10b which cannot be refilled and are used up and thrown away are used as fuel holding parts, it becomes a form in which the user confirms that the fuel cartridges 10a, 10b are used up and replaces them. In addition, a direct methanol fuel cell (DMFC) is used as the fuel cell. In the case of a panel type, there is known a fuel supply device on the anode side that uses at least one of fuel supply using an attractant using capillary action and fuel supply using a pump to circulate the fuel. In the case of a stack type, a structure is known in which a pump is used for the fuel supply device on the anode side and a fan or blower is used for the air supply device on the cathode side. In this embodiment, the device is constructed according to the above-mentioned structure.

Embodiment 2
[0079] Next, the configuration when using a refillable fuel tank instead of a fuel tank that is used up and thrown away will be described.
[0080] The fuel tank in this embodiment is shown in FIG. 13. The fuel supply side sealing material 13 in Embodiment 1 is detachable, and has a check valve 18 that can supply fuel to the outside only when it is installed.
[0081] Next, a method of refilling fuel into the fuel tank will be described with reference to figures.
[0082] The first refilling method is a method when the fuel tank is detached and refilled. As shown in FIG. 14 , fuel is pressurized using a filler 60 and refilled to the fuel tank side. The fuel for replenishment of the filler 60 can be seen visually, and the operation status such as replenishment in progress and replenishment completion can be displayed by LED or the like. By using at least one of the pressure sensor on the filler 60 side and the detection of the remaining amount from the fuel tank, it is possib...
Embodiment 3
[0087] Next, an embodiment in which a power generation unit cleaning function is added in addition to the first and second embodiments described above will be described.
[0088] In Example 1, cleaning was performed with a washer configured to be connected to fuel cartridges 10a, 10b and AC adapter 40 terminals in FIG. 2 . The cleaning fluid (pure water, etc.) is injected from one fuel tank, and the waste fluid is recovered from the other fuel tank.
[0089] In addition, power is supplied from the AC adapter 40 during cleaning.
[0090] In Example 2, it is connected to the connection part of the filler 60 in FIG. 15 . As in Example 1, a cleaning liquid (pure water, etc.) was injected, and waste liquid was recovered. During cleaning, power is supplied from the connection part of the filler 60 or the AC adapter 40 .
[0091] In Embodiment 3, the power generation assembly 30 is disconnected from the housing portion 20 and directly connected to the washer. Inject cleaning flui...
