## Abstract

An electrolysis device including a housing, an electrolysis plate, and a rotating element is provided. The housing has a first surface and a second surface that are opposite to each other. The electrolysis plate disposed in the housing includes a rotating plate, a working electrode, and a counter electrode. The working electrode and the counter electrode are respectively disposed on the rotating plate and separated from each other. The rotating element is pivotally disposed on the rotating plate, so that the electrolysis plate is able to rotate in the housing.

## Claims

### Claim 1

An electrolysis device, comprising:
a housing, having a first surface and a second surface that are opposite to each other;
an electrolysis plate, disposed in the housing and comprising:
a rotating plate;
a working electrode, disposed on the rotating plate; and
a counter electrode, disposed on the rotating plate and separated from the working electrode; and
a rotating element, pivotally disposed on the rotating plate, such that the electrolysis plate is able to rotate in the housing.

### Claim 2 (depends on 1)

The electrolysis device as claimed in claim 1, wherein the housing comprises an inlet and an outlet, the inlet and the outlet are respectively disposed on the first surface and the second surface, and the electrolysis plate is disposed between the inlet and the outlet.

### Claim 3 (depends on 2)

The electrolysis device as claimed in claim 2, wherein the rotating element penetrates through the second surface of the housing.

### Claim 4 (depends on 3)

The electrolysis device as claimed in claim 3, further comprising:
a driving device, connected to the rotating element and disposed at a side of the housing close to the second surface.

### Claim 5 (depends on 2)

The electrolysis device as claimed in claim 2, wherein the housing comprises a gas collecting opening disposed on the first surface and separated from the inlet.

### Claim 6 (depends on 2)

The electrolysis device as claimed in claim 2, wherein the rotating plate has a blind hole, and the electrolysis device further comprises:
a reference electrode, disposed in the blind hole.

### Claim 7 (depends on 6)

The electrolysis device as claimed in claim 6, wherein the reference electrode penetrates through the inlet.

### Claim 8 (depends on 6)

The electrolysis device as claimed in claim 6, wherein the electrolysis plate has a rotating axis, and the rotating axis penetrates through a center of the blind hole and a center of the rotating element.

### Claim 9 (depends on 1)

The electrolysis device as claimed in claim 1, wherein a rotating speed of the electrolysis plate is higher than 0 rpm and lower than or equal to 3000 rpm.

### Claim 10 (depends on 2)

The electrolysis device as claimed in claim 2, wherein a flow rate at which a solution to be electrolyzed flows into the housing via the inlet is F, and 0.1 L/min≤F≤10 L/min.
