介在していることを特徴とするものである。 Recently, electronic equipment has become more and more electronic.
It is small and lightweight, and power consumption has been significantly reduced. When commercial electricity is not available, dry batteries and secondary batteries are used as the power source for this type of equipment, and their low power consumption allows them to operate for long periods of time. However, since dry batteries cannot be regenerated once discharged, there are problems in terms of environmental conservation and effective use of resources. Also, secondary batteries can be regenerated by charging, but
There are problems such as it takes a long time to charge and the charge/discharge cycle life is short. In this respect, fuel cells have the advantage of being able to generate electricity as long as fuel and oxidizer are supplied. However, in a conventional fuel cell, as shown in FIG. A method was used in which a large number of stacked oxidizing chamber frames 8 each having a oxidizing chamber 7 were stacked. With this method, it is difficult to replace a failed unit battery, and when applied to electronic devices with low power consumption, the electrode area is small, so the battery frame occupies a large proportion, resulting in low weight and volumetric efficiency. The present invention aims to eliminate the above-mentioned drawbacks, and in order to achieve this objective, a unit cell member consisting of a fuel electrode, an electrolyte, and an oxidizer electrode, and a cylindrical case for a fuel chamber having a fuel supply hole to the fuel electrode in the side wall. , has an air supply cylindrical case with an air supply hole to the oxidizer electrode in the side wall, and an insulating sealing material,
The unit cell member is wound around the fuel chamber cylindrical case and housed in the air supply cylindrical case, and the sealing material is attached to the bottom and opening between the fuel chamber cylindrical case and the air supply cylindrical case. It is characterized by being interposed in the part.

The oxidizer electrode 13 is brought into close contact. Liquid-tightness and airtightness are maintained by these upper and lower end sealing materials 14, and the device is housed in an air supply cylindrical case 16 having a plurality of air supply holes 15 in the side wall. Oxidizer electrode 1
An oxidizing agent chamber 17, which is a space between the oxidizing agent electrode 3 and the air supplying cylindrical case 16, contains a wire gauze 18, which is a conductive member, and serves not only to reinforce the oxidizing agent electrode 13 but also to collect current. Electrical insulation between the air supply cylindrical case 16 and the fuel chamber cylindrical case 10 is provided by a sealing material 14. 19 is a cap for the cylindrical case 10 for the fuel chamber, and a gas discharge hole 20 is provided therein. Electric power can be generated by removing this cap 19 and supplying fuel or a mixed solution of fuel and electrolyte into the cylindrical case 10 for the fuel chamber.
