A detailed description of the body 110, the cathode 120, the anode 130, and the separator 140 will be omitted.

At least one of the cathode part 120 and the anode part 130 may have a plurality of protrusions formed on its surface. Accordingly, the area of contact with the material passing through the inside of the fuel cell 100 can be increased.

The power supply system 600 has a tubular structure with both open ends. Material for generating a current or voltage through the interior of the tubular structure with both open ends in the power supply system 600 can pass.

The power supply system 600 has a hollow tubular structure, in which a secondary battery unit 170 in the form of a tubular structure is disposed, a transformer circuit unit 180 in the form of a tubular structure is disposed inside the secondary battery unit 170 And the predetermined size of the battery units 110 to 140 are disposed inside the transformer circuit unit 180 to form a tubular structure with both open ends.

The electrodes 110 to 140 generate a voltage or an electric current by using a material introduced through an opening formed in the power supply system 600. [ Operations for generating a voltage or a current are duplicated and therefore will not be described.

The voltage transforming circuit unit 180 regulates the magnitude of the voltage or the current generated in the cell units 110 to 140. The transforming circuit portion 180 may be implemented with at least one of a DD converter and a DA converter.

Since the voltage generated in the charge units 110 to 140 is often less than 1 V, the voltage or current generated in the charge units 110 to 140 is insufficient to be applied to various devices or electronic devices. Accordingly, the voltage transforming circuit unit 180 can increase the voltage generated in the power units 110 to 140 to change the current density in a form that can be used in various devices or electronic devices. Alternatively, the voltage transforming circuit unit 180 can adjust the current density to change the current density in a form that can be used in a device or an electronic device, instead of boosting the voltage.

The secondary battery 170 is charged using the voltage or current of the adjusted magnitude in the transformer circuit unit 180.

Thereafter, the secondary battery 170 can be discharged by supplying the charged voltage or current to the device or the electronic device when electricity is required in the device or the electronic device. The secondary battery 170 is preferably implemented as a secondary battery capable of charging or discharging, but may be implemented using one or more capacitors.

Unlike the power supply system 600 shown in FIG. 6, the battery units 110 to 140 are located inside the transformer circuit unit 180 and may have a cylindrical structure surrounded by the transformer circuit unit 180. According to an example, both the battery units 110 to 140, the voltage transforming circuit unit 180, and the secondary battery unit 170 are both in the form of a circular column, and the cross section of the power supply system 100 may be circular.

The power supply system 600 is disposed in the form of surrounding the secondary battery unit 170 at the outer sides of the battery units 110 to 140, the voltage transformer circuit unit 180 and the secondary battery unit 170, The transformer circuit unit 180, and the secondary battery unit 170, as shown in FIG.

The power supply system 600 may further include a second body unit (not shown) disposed between the transformer circuit unit 180 and the charge units 110 to 140. The second body portion (not shown) may be a tubular structure having openings at both ends thereof.

Meanwhile, since the fuel cells 110 to 140 of the power supply system 600 are overlapped with the fuel cell 100 described with reference to FIGS. 1 to 5, the description of the overlapping portions will be omitted.

The anode portion B and the anode portion B are disposed inside the body portion 710, For convenience of explanation, a separator is not shown in Fig. 7B.

As an example, the cathode portion A of each of the plurality of cells 720 may be connected to each other by a wire, and the anode portion B of each of the plurality of cells 720 may be connected to each other by a wire.

In FIGS. 7A and 7B, the number of cells 720 is four, but the present invention is not limited thereto.

Operations of each of the plurality of cells 720a, 720b, 720c, and 720d are the same as those of the above-described operations of FIGS. 1 to 5, and thus description of overlapping portions will be omitted.

According to another aspect of the present invention, there is provided a power supply system including: a power source for generating a voltage or a current using a material introduced through an opening formed in a power supply system; And a secondary battery unit that is charged using a voltage or current of a size adjusted by the voltage transformer circuit unit, wherein the battery unit is a tubular structure having openings at both ends thereof, And a plurality of cells arranged in series in the other end direction at one end of the body portion, wherein each of the plurality of cells is disposed inside the body portion, A cathode part disposed inside the body part for receiving electrons, and a cathode part for separating the anode part and the anode part from each other inside the body part, ≪ / RTI >

In this case, the transforming circuit portion can perform the DA conversion.

On the other hand, the power supply positive system may be implemented without a transformer circuit portion.

Referring to FIG. 8A, the fuel electrode may be a cathode portion, and the air electrode may be an anode portion. The cathode portion and the anode portion may be separated from each other by an electrolyte.

In this case, electrons are received from the anode using supplied hydrogen, electrons are transferred to the cathode, and electrons are provided from the cathode.

In FIG. 9B, microorganisms and wastewater can be put into the cell at the same time to cause a reaction. Since the specific operation principle is the same as that in FIG. 9A, the description of overlapping portions will be omitted.

On the other hand, enzymatic biofuel cells using enzymes can utilize blood. The specific operation principle is the same as that of the biofuel cell using the microorganisms described in Figs. 9A and 9B.

Enzymes of biofuel cells using enzymes can be divided into oxidases and reductases. Oxidizing enzymes make hydrogen in the anode, and can include laecause, bilirubin oxidase, and the like.
