Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrogen production by water electrolysis, and in particular to an electrolyzer assembly. Background Technology
[0002] Electrolytic cells require a support structure during use. In practical applications, existing copper foil electrolytic cell support structures, due to the arc-shaped side surfaces and friction, may cause the cell's center of gravity to be located in the upper half, posing a risk of rolling and tipping. Furthermore, the cylindricity control of the inner arc surface of the support plate is inaccurate. Since the existing anode support plate is supported only by two thin stainless steel side plates, which lack rigidity, the support effect on the anode support plate is poor.
[0003] Patent CN205024334U discloses a support structure for a copper foil electrolytic cell, including a support base and an electrolytic cell support. The electrolytic cell support includes two opposing cell support frames, each with a side plate and an arc-shaped support groove. An outer ring plate is located on the inner wall of the arc-shaped support groove, and an inner ring plate is located at the inner end of the outer ring plate. An inlet tank support frame is connected between the bottom of the inner ring plates of the two cell support frames. An overflow tank support rod is connected between the two ends of the inner ring plates of the two cell support frames. A reinforcing support rod is also connected between the inner ring plates of the two cell support frames. Connecting holes are provided on the outer ring plate, the inlet tank support frame, the overflow tank support rod, and the reinforcing support rod. A reinforcing rod is connected between the bottom of the side plates of the two cell support frames. A support frame connecting plate is located along the length of the lower end of the side plate. This utility model has high overall structural strength, a large contact support area, prevents processing deformation, ensures the roundness and flatness of the side plates, provides good sealing effect, and has a long service life.
[0004] However, the use of curved contact surfaces in the comparison documents still makes it difficult to solve the rolling problem when the gravitational potential energy is high.
[0005] An electrolytic cell is needed to solve the above problems. Utility Model Content
