Description

Technical Field

[0001] This utility model relates to the field of water electrolysis clamps, specifically a temperature-controlled water electrolysis clamp. Background Technology

[0002] Among the various hydrogen production technologies currently available, using electricity generated from renewable energy sources as power for water electrolysis is the most mature technology. Water electrolysis for hydrogen production has advantages such as high efficiency and environmental friendliness, and is considered to be the main hydrogen production method in the future. The flow channel plate is an important component of the water electrolysis hydrogen production fixture. It not only separates water from the catalyst and prevents gas from passing through, but also collects and conducts current. Therefore, the design of the flow channel plate is extremely important, as it ensures the output performance of the membrane electrode in the fixture.

[0003] Existing water electrolysis fixtures are not convenient for internal temperature control. In low-temperature environments, the electrolyte flow rate slows down, which not only increases energy consumption and reduces electrolysis efficiency, but also increases the risk of equipment failure. Therefore, a temperature-controlled water electrolysis fixture is proposed to address the above problems. Utility Model Content

[0008] Preferably, the sealing gaskets are made of PTFE material, and one side of each of the two sealing gaskets contacts the other side of the water flow bipolar plate and the hydrogen flow bipolar plate, respectively.

[0009] The PTFE gasket has extremely high chemical stability and can resist the erosion of most chemicals.

[0010] Preferably, one of the flow channels is serpentine in shape, the inner cavity of one of the flow channels is connected to the inner cavity of the hydrogen outlet, and the inner cavity of the other flow channel is connected to the inner cavities of the oxygen outlet and the water inlet, respectively.

[0011] Preferably, a first sealing groove is provided on one side of the oxygen outlet, and a second sealing groove is provided on one side of the hydrogen outlet.

[0014] The advantages of this utility model are:

[0015] This invention, by setting up a bipolar plate assembly, installs a temperature sensor body and a heating rod body inside the bipolar plate of the water flow channel, which enables temperature control of the internal electrolyte.

This solves the problem that existing water electrolysis clamps are not convenient for internal temperature control, and that in low-temperature environments, the electrolyte rate slows down, which not only increases energy consumption and reduces electrolysis efficiency, but also increases the risk of equipment failure.

One side of both the water channel bipolar plate 301 and the hydrogen channel bipolar plate 302 is in contact with one side of the guide plate 2. The surface of the water channel bipolar plate 301 is provided with a temperature sensor mounting hole 303 and a heating rod mounting hole 304. An oxygen outlet 305 is provided on the surface of the water channel bipolar plate 301, and a water inlet 306 is provided at the bottom of the water channel bipolar plate 301. A hydrogen outlet 307 is provided on the surface of the hydrogen channel bipolar plate 302. The water channel bipolar plate 301 and the hydrogen channel bipolar plate 302... 2. A flow channel body 308 is provided on each opposite side. A temperature sensor body 311 is fixedly installed in the inner cavity of the temperature sensor mounting hole 303, and a heating rod body 312 is fixedly installed in the inner cavity of the heating rod mounting hole 304. By setting up the bipolar plate assembly 3, the temperature sensor body 311 and the heating rod body 312 are installed inside the water flow channel bipolar plate 301, which can control the temperature of the electrolyte inside. On the one hand, heating can reduce the resistance of the electrolyte and reduce energy consumption. On the other hand, appropriate temperature helps to increase the current density, thereby accelerating the electrolysis rate.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Both the water flow bipolar plate 301 and the hydrogen flow bipolar plate 302 are made of titanium alloy, as is the guide plate 2. The titanium alloy materials of the water flow bipolar plate 301, hydrogen flow bipolar plate 302, and guide plate 2 provide excellent corrosion resistance, enabling them to operate stably for extended periods in harsh environments and extending the equipment's service life.

[0028] Reference Figure 1 and Figure 2 The sealing gasket 4 is made of PTFE material. One side of the two sealing gaskets 4 is in contact with the other side of the water flow channel bipolar plate 301 and the hydrogen flow channel bipolar plate 302, respectively.

[0029] Reference Figure 5 One of the flow channels 308 is serpentine in shape. The inner cavity of one flow channel 308 is connected to the inner cavity of the hydrogen outlet 307, and the inner cavity of the other flow channel 308 is connected to the inner cavities of the oxygen outlet 305 and the water inlet 306, respectively.

By setting the titanium felt 5, it helps the adsorption and diffusion of gas molecules, and can achieve rapid response to changes in gas concentration.

[0032] Working principle: During use, the operator installs the heating rod body 312 and the temperature sensor body 311 into the inner cavity of the heating rod mounting hole 304 and the temperature sensor mounting hole 303. The heating rod body 312 can increase the temperature of the electrolyte, thereby accelerating the electrolysis reaction rate. During the electrolysis of water, as the temperature rises, the movement speed of water molecules increases, the probability of ionization increases, and thus the electrolysis efficiency is improved. This means that more hydrogen and oxygen can be produced in the same amount of time, increasing the production capacity of electrolyzed water. Furthermore, the serpentine flow channel body 308 can effectively guide the flow of reaction gases, reduce the ineffective emission of hydrogen, and improve the utilization rate of hydrogen.
