Description

Technical Field

[0001] The utility model relates to the technical field of electrolysis devices, in particular to a segmented multi-electrode sheet-shaped water electrolysis cell group. Background Art

[0002] At present, most water electrolysis cell groups on the market are assembled from multiple electrolysis units, and each electrolysis unit is embedded with two electrolysis plates to isolate an electrolysis chamber, which is an independent electrolysis unit. Although this design can achieve the function of electrolysis, there are still certain problems in use. For example, under this design scheme, when a set of electrolysis cell groups requires fourteen such electrolysis units, there are a total of three times fourteen, which equals forty-two electrolysis chambers. The length of the entire electrolysis cell is determined by this, and the length of the entire equipment is also fixed. However, as the use of the equipment changes, the disadvantages brought by the length of the equipment gradually become apparent. Users do not have such a large usage site, which leads to the need to optimize and shorten the length of the equipment. At the same time, some users require gas production equipment with a larger gas production capacity, but the length of the equipment cannot be increased too much. For this reason, we propose a segmented multi-electrode sheet water electrolysis cell group to solve the problems in the above background. Utility Model Content
