Description

[Detailed description of the invention] The present invention relates to a flat liquid fuel cell.

In recent years, electronic equipment has become more and more electronic.
They are smaller, lighter, and consume less power. BACKGROUND OF THE INVENTION Dry cells and secondary batteries are used as power sources for portable home appliances such as video tape recorders and cameras. This type of battery is also used for computer memory backup, strobe light power supplies, etc., and its applications are expected to expand further. However, since dry batteries cannot be regenerated once they are discharged, there are problems in terms of effective resource utilization and environmental conservation. Rechargeable batteries take time to charge and cannot be charged in places where commercial electricity is not available. Fuel cells, on the other hand, have the advantage of being able to generate electricity as long as fuel and oxidizer are supplied. The conventional structure of the fuel cell is as shown in FIG. 1, in which a stacked body consisting of a fuel electrode 1, an electrolyte 2, and an oxidizer electrode 3 is integrated with a cell frame 5, and a fuel chamber frame 7 having a fuel chamber 6 is attached to the fuel cell frame 5. It is constructed by stacking a large number of oxidizer chamber frames 9 having oxidizer chambers 8 on the oxidizer electrode 3 on the pole 1 side. When this fuel cell was applied as a power source for electronic equipment, the weight and volume efficiency were low, and maintenance was difficult.

The present invention aims to eliminate the above-mentioned drawbacks, and in order to achieve this objective, a laminate consisting of a fuel electrode, an electrolyte, and an oxidizer electrode, the periphery of which is integrated with a sealing material, is used to supply an oxidizer to the oxidizer electrode. It has a flat case having a small hole at its bottom and a fuel storage case for supplying fuel to the fuel electrode, the laminate is inserted into the bottom of the flat case, and the flat case and the fuel storage case have openings. It is characterized by the fact that comrades are intertwined.

An embodiment of the present invention will be described with reference to the drawings.

FIG. 2 shows a flat liquid fuel cell according to the present invention. The periphery of a stacked body consisting of a fuel electrode 10, an electrolyte 11, and an oxidizer electrode 12 is integrated with a sealing material 13, and this is placed in a case 15 having a plurality of oxidizer supply holes 14 on the bottom surface. A conductive spacer 17 is inserted between the oxidizing agent electrode 12 and the case 15 to form an oxidizing agent chamber 16, and the case 15 is electrically connected to the oxidizing agent electrode 12. A fuel storage case 18 serving as a fuel chamber has a fuel supply port 19 and a gas discharge hole 20. 21 is a cap,
Reference numeral 22 is a porous water-repellent membrane that selectively allows only gas to pass through, or a gas purifier that decomposes a small amount of harmful gas. Case 15 and fuel storage case 18 are integrated by sealing material 13 and are electrically insulated.

Since the present invention is constructed as described above, it is superior to conventional ones in terms of weight and volume efficiency, and when high voltage is required, it is only necessary to electrically connect a large number of them, and it is easy to maintain. It is also easy to remove only the failed battery from the connected ones, and furthermore, it can be applied to fields where dry batteries and secondary batteries are used, and its industrial value is extremely large.
