Detailed Description
Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In addition, when the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise indicated. The terms "first," "second," and the like, as used in this disclosure, are used for distinguishing one element from another and not necessarily for order or importance.
The present disclosure provides an electrolytic cell for producing hydrogen by electrolyzing water, as shown in fig. 1 to 3, including a plurality of annular electrode frames 1 stacked along an axis direction of the electrolytic cell, and a gasket 4 disposed between two adjacent electrode frames 1, and the gasket 4 may be disposed between two electrode frames 1, to play a sealing role, to ensure that the electrolytic cell does not leak electrolyte. The space of the inner periphery of the pole frame 1 is provided with a circular-plate-shaped pole plate 2, the pole plate 2 is positioned at the middle position of the inner periphery of the pole frame 1 along the thickness direction, the distance between two adjacent pole plates 2 is 11mm-12mm, and the thickness of the pole plate 2 is 0.5mm-1.5mm. The above-mentioned thicknesses refer to the left-right direction in the direction of the drawing of fig. 1 in fig. 1, and refer to the up-down direction in the direction of the drawing of fig. 3 in fig. 3.
Through the technical scheme, the temperature of the electrolyte in the accommodating cavity can be more balanced and the heating time of the electrolyte is saved by adjusting the distance between the two adjacent polar plates 2, and the power consumption is reduced by saving the heating time. In the electrolytic tank, the accommodating cavity capable of accommodating electrolyte is formed by enclosing the side surfaces of two adjacent polar plates 2 and the inner peripheral space of the polar frame 1, so that one polar frame 1 can form two accommodating cavities, if the distance between the two adjacent polar plates 2 is too large, the volumes of the electrolyte accommodated by the two adjacent accommodating cavities are different, the temperature of the electrolyte at the central position of the accommodating cavity with larger volume of the electrolyte is difficult to reach the temperature required by the electrolytic operation standard in time when the accommodating cavity is heated, and the electrolytic efficiency is further influenced. The polar plate 2 is arranged at the middle position of the inner peripheral surface of the polar frame 1 along the thickness direction, so that the volumes of the containing cavities at the two sides of the polar plate 2 are the same, the heating time required by a plurality of containing cavities is the same, and the electrolytic efficiency of a plurality of containing cavities in the electrolytic tank is ensured to be the same respectively. Meanwhile, in the electrolysis process, the current is lost when flowing through the polar plate 2 due to the existence of the resistance of the polar plate 2, so that the electricity consumption in the electrolysis process is increased, and the thickness of the polar plate 2 is configured to be between 0.5mm and 1.5mm, so that the influence of the resistance of the polar plate 2 on the electrolysis operation can be effectively reduced, the electricity consumption of the electrolysis operation is further reduced, meanwhile, the axial size of the electrolytic tank is reduced due to the thinner polar plate 2, the weight of the electrolytic tank is reduced, the axial installation size is reduced, and meanwhile, the structural strength of the polar plate 2 is not influenced.
The inner peripheral surface of the pole frame 1 can be radially inwards provided with annular tongue plates 3 in a protruding mode, and the pole plates 2 are fixedly connected with the tongue plates 3. Because of the existence of the tongue plate 3, the distance between the polar plate 2 and the inner peripheral surface of the polar frame 1 is larger, and when the polar plate 2 is installed, an installation tool cannot be interfered by the inner peripheral surface of the polar frame 1, so that more operation space is provided during installation, and the polar frame 1 and the polar plate 2 are convenient to connect and install. In the case of welding in the connection manner mentioned below, the tongue plate 3 can also prevent thermal deformation of the pole plate 2 and the pole frame 1 due to welding.
Further, the polar plate 2 may be connected to the tongue plate 3 by welding. The sealing performance between the polar plate 2 and the polar frame 1 can be ensured by welding, and the electrolysis effect of the electrolytic tank is ensured. The width of the welding seam 21 at the connecting position of the polar plate 2 and the tongue plate 3 can be more than or equal to 0.5mm. In fig. 1 or 3, the weld 21 at the connection location of the plate 2 and the tongue plate 3 may be a butt weld 21, and with further reference to fig. 3, the width of the weld 21 is indicated by a linear distance C in fig. 3. The stress of the weld 21 having a sufficient width is more uniform to ensure the strength of the weld. If the width of the weld 21 is too small, it is difficult to ensure the connection strength between the tongue plate 3 and the electrode plate 2 and the tightness of the connection position, and the service life of the electrolytic cell is difficult to ensure.
In fig. 3, the first side 11 of the pole frame 1 may be provided with a first step 12 for mounting a separator and a second step 13 for mounting a first electrode in a height gradually decreasing from outside to inside, and the above-mentioned "from outside to inside" refers to a direction from the outer ring toward the inner ring of the pole frame 1, and in fig. 3, from left to right in the direction of the drawing of fig. 3 refers to "from outside to inside" of the pole frame 1. The second side 14 of the pole frame 1 is provided with a third step 15 for mounting the second electrode. The separator can separate hydrogen and oxygen generated in the electrolysis operation, and the electrode can provide ions required for electrolysis into the electrolyte. The step part can accommodate the diaphragm and the electrode required by electrolysis, and simultaneously further lightens the weight of the pole frame 1, and is convenient for positioning and mounting the diaphragm and the electrode. When a plurality of electrode frames 1 are required to be stacked, the adjacent electrode frames 1 are not affected by the thickness of the diaphragm and the electrode, and accordingly, the axial dimension of the electrolytic cell is reduced.
The pole frame 1 can be provided with a liquid inlet hole 16 and a liquid outlet hole 17, liquid storage cavities 18 for storing electrolyte are formed on the two side surfaces of the pole plate 2 and the inner peripheral space of the pole frame 1, and the liquid outlet hole 17 and the liquid inlet hole 16 are respectively communicated with the liquid storage cavities 18. The reservoir 18 may be formed as part of the receiving cavity, and two reservoirs 18 between adjacent plates 2 may be formed as the entire receiving cavity. Thus, the liquid inlet hole 16 can supplement electrolyte into the liquid storage cavity 18 and recover oxygen generated in the electrolysis process, and the liquid outlet hole 17 can collect hydrogen generated in the electrolysis operation and recover the electrolyzed electrolyte, so that the stable operation of the electrolytic tank is ensured. The liquid outlet hole 17 and the liquid inlet hole 16 can be arranged with specific reference to fig. 2 while ensuring the communication with the liquid storage cavity 18, namely, the liquid outlet hole 17 and the liquid inlet hole 16 can be vertically communicated with the pole frame 1, so that the liquid storage cavities 18 of the pole frames 1 can be mutually communicated when the pole frames 1 are arranged in a stacked manner, electrolyte can be simultaneously supplemented into the liquid storage cavities 18 of the pole frames 1 and oxygen generated in the electrolysis process can be recovered through the liquid inlet hole 16, and the liquid outlet hole 17 can also simultaneously collect hydrogen generated in the electrolysis operation of the liquid storage cavities 18 of the pole frames 1 and recover the electrolyzed electrolyte, so that the electrolysis efficiency of the electrolytic tank is effectively improved.
Further, the liquid outlet hole 17 and the liquid inlet hole 16 may be symmetrically arranged radially with respect to the pole frame 1, and the liquid outlet hole 17 and the liquid inlet hole 16 have a plurality of liquid outlet holes, respectively. In fig. 2, a plurality of liquid outlet holes 17 and liquid inlet holes 16 can be operated simultaneously to further improve the electrolysis efficiency, and the radial symmetrical arrangement is also more convenient for stacking and mounting the pole frame 1.
The first side 11 of the pole frame 1 and/or the second side 14 of the pole frame 1 may be provided with a notch 19 that can cooperate with the spacer 4. The displacement of the spacer 4 in the radial direction of the pole frame 1 can be avoided by the notch 19. In fig. 1, the first side 11 and the second side 14 of the pole frame 1 are both provided with notches 19. In order to enable the gasket 4 to exert a better sealing effect, the gasket 4 is generally made of elastic materials such as rubber, when the gasket 4 is installed in two adjacent pole frames 1, the gasket 4 is extruded, and due to the gap 19, the gasket 4 is partially embedded into the gap 19, so that the gasket 4 can resist displacement along the radial direction of the pole frames 1 in the use process.
In addition, the outer surfaces of the electrode frame 1 and the electrode plate 2 may be provided with a nickel layer. In the electrolytic operation, can produce a lot of alkaline ions, these alkaline ions can corrode polar frame 1 and polar plate 2, reduce polar frame 1 and polar plate 2's life, consequently can be provided with the nickel layer at polar frame 1 and polar plate 2's surface, avoid alkaline ions to the corruption of polar frame 1 and polar plate 2's surface, the nickel layer can also improve polar frame 1 and polar plate 2's surface's wearability simultaneously, improves polar frame 1 and polar plate 2 life and use intensity. The nickel layer can be arranged in a plating mode, so that the nickel layer is uniformly and firmly arranged.
In the present disclosure, the difference between the outer radius of the pole frame 1 and the inner radius of the pole frame 1 may be 72mm-102mm, and the diameter of the pole plate 2 may be 1795mm-1835mm. When the distance between two adjacent polar plates 2 is fixed, the diameter of the polar plates 2 is enlarged, so that the volume of electrolyte in the accommodating cavity can be increased, and the efficiency of electrolytic operation is improved. The outer radius of the pole frame 1 and the inner radius of the pole frame 1 can refer to fig. 3, the outer radius of the pole frame 1 is represented by a linear distance a in fig. 3, the inner radius of the pole frame 1 is represented by a linear distance B in fig. 3, and the difference between the linear distance a and the linear distance B is 72mm-102mm, so that the electrolytic cell is convenient to install the diaphragm and the gasket 4, and the use effect of the electrolytic cell is also ensured. When the difference between the linear distance a and the linear distance B is too small, it is difficult to mount the diaphragm and the gasket 4 between the adjacent pole frames 1, and the sealing property of the electrolytic cell cannot be ensured. When the difference between the linear distance A and the linear distance B is too large, the radial dimension of the electrolytic cell is too large, more installation space is occupied, and the production cost is increased. The present disclosure is not limited to a specific limitation, and the difference between the outer radius of the pole frame 1 and the inner radius of the pole frame 1 may be adaptively adjusted according to the size of the pole plate 2, where when the size of the pole plate 2 is smaller, the smaller the difference between the outer radius of the pole frame 1 and the inner radius of the pole frame 1, and correspondingly, when the size of the pole plate 2 is larger, the larger the difference between the outer radius of the pole frame 1 and the inner radius of the pole frame 1.
