[0002] In electrochemical manufacturing, especially batteries, the stability of electrodes in aqueous environments is directly related to battery performance. Hydrogen produced by water decomposition at metal electrodes reduces the battery's energy density and Coulombic efficiency. Furthermore, the hydrogen evolution reaction can increase internal pressure in the battery, disrupting the internal structure and causing safety issues. Furthermore, hydrogen production can also cause dendrites to form within the battery, further reducing battery performance. Therefore, the ability of an electrode to produce hydrogen in an aqueous environment has become a crucial indicator of electrode stability.

[0003] In traditional electrochemical hydrogen production devices, the electrodes are difficult to remove and place, and the electrolyte consumption is high, resulting in high operating costs of the device and hindering the detection of the electrode's hydrogen production capacity.

[0028] Example 1:

[0029] like Figure 1 As shown in the figure, a novel electrode hydrogen production measuring device disclosed in the present invention comprises an electrolytic box 1, a gas chromatograph 2 and an electrochemical workstation 3. The main components of the present invention are described in detail below:

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the electrolytic box 1 includes an electrolytic box body 11. The top of the electrolytic box body 11 is provided with an operating hole 11a that communicates with the interior. A sealing end cap 12 is provided at the operating hole 11a. The outer periphery of the sealing end cap 12 is connected to the inner wall of the operating hole 11a via threads to ensure internal sealing. Two positioning and mounting holes 11b are provided on the side of the electrolytic box body 11 near the bottom. Each positioning and mounting hole 11b is provided with an L-shaped electrode clamp 13. The front end clamp of the L-shaped electrode clamp 13 is a fish-mouth clamp, which facilitates the removal and placement of the electrode to be tested. The front end clamp of the L-shaped electrode clamp 13 is located inside the electrolytic box body 11. An integrally formed glass arm 14 is provided on the side of the electrolytic box body 11 near the top. Both the electrolytic box body 11 and the glass arm 14 are made of transparent material, facilitating observation of the interior of the electrolytic box 1. There are two glass arms 14, which are arranged on opposite sides of the electrolytic box body 11. The glass arms 14 are L-shaped and have an anti-slip layer on their outer surface. The glass arms 14 are provided with an air guide channel 14a that communicates with the interior of the electrolytic box body 11. It should be noted that the above structure is merely an example and not a limitation. In this embodiment, the two positioning and mounting holes 11b are provided on the same side of the electrolytic box body 11. However, in other embodiments, the two positioning and mounting holes 11b are provided on different sides of the electrolytic box body 11.

[0031] like Figure 1 and Figure 2 As shown, the gas chromatograph 2 is connected to the gas guide channel 14a through the gas guide tube, and uses the chromatography principle to separate and analyze the gas mixture transported from the gas guide channel 14a to determine the hydrogen content therein.

[0032] like Figure 1 and Figure 2As shown, the electrochemical workstation 3 is connected to the rear end of the L-shaped electrode clamp 13 and is used to control and detect changes in current, potential and other electrochemical parameters in the electrolysis box.

[0033] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the principle and use method of the novel electrode hydrogen production measuring device of the utility model are as follows: when the electrode hydrogen production needs to be measured, the electrolytic box 1 is placed on a flat surface, and then the electrode to be measured is inserted into the L-shaped electrode clamp 13 by pointed tweezers for fixation. In this process, since the front end clamp of the L-shaped electrode clamp 13 is a fish mouth clamp, the electrode to be measured only needs to be lightly pressed from top to bottom from the opening of the fish mouth clamp to complete the fixation, and the operation difficulty is low; pour an appropriate amount of suitable electrolyte to immerse the electrode to be measured, tighten the sealing end cover 12, use the glass arms 14 on both sides to connect the gas chromatograph 2, and connect the L-shaped electrode clamp 13 to the electrochemical workstation 3 to start measurement.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed herein are intended to be covered by the claims of the present invention.
