一种设有多电流输入接线柱的碱水电解槽装置An alkaline water electrolyzer device equipped with multiple current input terminals 技术领域Technical field

Hydrogen energy is a brand-new energy system, and its preparation process is the key core. Alkaline electrolysis of water for hydrogen production can be coupled with electricity, and the electrolyzer also has a certain adaptability to power fluctuations. The advantage of this method is that the hydrogen produced is of high purity, the subsequent purification process is simple, and the raw material for hydrogen production is water, so there is no need to worry Insufficient resources problem. With the development of alkaline electrolyzer technology, the research demand for large-scale alkaline electrolyzers has gradually increased.

然而，对于大型的碱水电解槽，输入的电流密度大，由于气泡、传质和传热等因素的影响，对于单一的电流输入接线柱电解小室内的电阻分配极不均匀，进而会导致电流分布不均，使电解槽工作无法稳定。However, for large alkaline water electrolyzers, the input current density is large. Due to the influence of bubbles, mass transfer, heat transfer and other factors, the resistance distribution in the electrolysis cell for a single current input terminal is extremely uneven, which in turn causes the current Uneven distribution makes the electrolytic cell work unstable.
