なった。以下、これらについて図を参照して説明する。[Problems to be Solved by the Invention] However, as research into thin-film oxide electrodes progresses, it has become clear that if the cathode and anode are immersed in an electrolyte with no current applied, the potential difference between the cathode and anode will increase. It has become clear that reduction of n2 oxide occurs due to the reverse current generated by this process, causing problems such as increased consumption of the thin film type oxide electrode. These will be explained below with reference to the drawings.

If the potential of the negative electrode 11i4 is E2, then E=21-E2 (E2
<O) ...There is a voltage load of (1),
A reverse current flows from the cathode 4 to the anode #13 via the electrolyte, and the anode 3 is reduced. The magnitude of this reverse current and the total amount of current depend on the electric charge stored in the electric double layer formed at the interface between the electrode and the electrolyte, the rectifier resistance, the electrolyte resistance, and the polarization resistance of the electrode, as shown in Figure 6. The result will be a curve like this.

複雑となる。(B) When the anode and cathode are on one substrate Figure 5-
Considering an electrolysis device in which an electrode with a cathode and an anode is installed on a single substrate as shown in (c) and (d), the flow of current before and after stopping electrolysis is shown in Figure 7. . Figure 7 (
Figure 7 (a) shows the flow of current during electrolysis in an electrode in which the front and back sides of a single substrate serve as an anode and cathode, respectively, and Figure 7 (b) shows the current flow after electrolysis is interrupted. This shows the flow. Figure 7 (C) shows the current direction during electrolysis when the top and bottom of one side of one base material and the top and bottom of both sides serve as cathodes and anodes, and Figure 7 (d) shows the direction of current during electrolysis after discontinuing electrolysis. This shows the direction of current. Note that the current after discontinuing electrolysis is the 7th
In addition to flowing in the direction of the arrows as shown in Figures (1) and (d), stray currents and the like must also be taken into consideration, making the process more complicated.

従って消耗量も大きくなる。Furthermore, in the case of an electrode in which a cathode and an anode exist on a single substrate, a sufficient reverse current can flow even if the electrode is in a wet state after draining the electrolyte, so the conditions are stricter than in the case of (A) above. ,
Therefore, the amount of consumption also increases.

能になる。[Function] Since this device with such a configuration is provided with a rectifying means between the anode and the cathode or on the electrical connection line between the anode and the cathode, current flows through these electrodes in only one direction. . Therefore, the reverse current generated after the rectifier power is turned off is suppressed by the rectifier, and the flow of the reverse current into the anode can be suppressed. This makes it possible to solve the above problems. Further, the device of the present invention uses, for example, a semiconductor diode (rectifying element, etc.) as the rectifying means.
By using , it is possible to obtain a large resistance against the reverse current that occurs at the same time as electrolysis is stopped, and it becomes possible to significantly reduce the reverse current.
