Problems solved by technology

However, in a fuel cell, as long as the concentration of the fuel that fills the power generation part does not change, no change appears in the output characteristics, and the power generation voltage does not decrease until the fuel is used up.
Therefore, it becomes a problem to detect the remaining amount of fuel or supply power to the load with high efficiency due to stable fuel supply.

Embodiment 1

[0038] figure 1 It is an external view of installing the fuel cell device of the present invention on a load, figure 2 A block diagram of a 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

[0080] Next, the configuration when using a refillable fuel tank instead of a fuel tank that is used up and thrown away will be described.

[0081] The fuel tank in this embodiment is as Figure 13 As shown, 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 attached.

[0082] Next, a method of refilling fuel into the fuel tank will be described with reference to figures.

[0083] The first refilling method is a method when the fuel tank is detached and refilled. Such as Figure 14 As shown, the fuel is pressurized using the 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 fue...

Embodiment 3

[0088] 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.

[0089] In Example 1, with figure 2 The washer in which the fuel cartridges 10a, 10b and the terminals of the AC adapter 40 are connected is cleaned. The cleaning fluid (pure water, etc.) is injected from one fuel tank, and the waste fluid is recovered from the other fuel tank.

[0090] In addition, power is supplied from the AC adapter 40 during cleaning.

[0091] In Example 2, with Figure 15 The filler 60 connection part in the connection. 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 .

[0092] In Embodiment 3, the power generation assembly 30 is disconnected from the housing portion 20 and directly connected to the washer. Inject cleaning fluid (pu...

Abstract

To provide a high-efficiency fuel cell device and electronic equipment capable of detecting the fuel remaining amount of the fuel cell device with a simple structure, and also capable of easily changing the fuel holding unit even when the fuel remaining amount decreases. For this purpose, two or more fuel holding units having a function of detecting the remaining fuel amount are provided, and a fuel cell device capable of selecting a fuel holding unit that can be used during load driving is produced. Thereby, it is possible to provide a fuel cell device capable of realizing freedom of direction of the fuel holding unit, detection of the remaining amount, and efficient fuel exchange, and high reliability during load use.

Description

[0001] This application is a divisional application of the invention patent application with the application number 200410071343.3, the application date is July 20, 2004, and the invention name is "fuel cell device and electronic equipment". technical field [0002] The present invention relates to a fuel cell device and electronic equipment incorporating the device. Background technique [0003] With the advancement of electronic technology in recent years, telephones, notebook personal computers, audio-visual equipment, mobile terminal equipment, etc. have been miniaturized and are rapidly becoming popular as portable electronic equipment. As a power source for portable electronic equipment, a fuel cell power source is considered. Since the fuel cell directly converts the chemical energy of the fuel electrochemically into electrical energy, it does not require a power unit such as a generator using an internal combustion engine such as a general engine generator, and is ve...
