Description

Technical Field

[0001] The invention relates to the field of equipment for producing hydrogen by electrolyzing water, and in particular to a transparent electrolytic cell with adjustable conductive contacts. Background Art

[0002] As an ideal clean energy, hydrogen energy has attracted much attention due to its high efficiency and environmental protection. As an important device in the hydrogen production process, the energy efficiency of the electrolyzer greatly restricts the economic efficiency of the water electrolysis hydrogen production system. In addition, the current single-cell electrolyzer pursues high power, which results in an increase in the electrode reaction area and an increase in the diameter of the electrolysis chamber. The increase in the diameter of the electrolysis chamber will more easily lead to uneven distribution of the chamber flow field, and there may also be dead zones in the flow of the electrolyte, affecting the temperature distribution and reaction efficiency of the electrolysis chamber, thereby causing a decrease in the efficiency of the electrolyzer.

[0003] The flow field distribution inside the electrolytic chamber can only be predicted through simulation data and experimental data. The observation means are limited, and it is impossible to accurately and deeply understand the flow and distribution of electrolyte and gas in the internal flow field, which also affects the subsequent optimization of the flow field structure. In order to solve the above problems, there is an urgent need for a device that is close to the actual working conditions, improves the efficiency of the electrolytic cell, and can facilitate the observation of the electrolytic cell conditions.

[0004] The present invention is proposed for this purpose. Summary of the invention

[0010] Beneficial effects of the present invention:

[0011] 1. The transparent electrolytic cell with adjustable conductive contacts of the present invention provides a potential difference for the cathode and anode through the positive and negative electrodes, so that an electrolytic reaction occurs in the electrolytic cell to produce hydrogen and oxygen.
