[0002] As a clean and efficient way to obtain energy, hydrogen production by electrolyzing water has received extensive attention in recent years. Especially for alkaline water electrolysis for hydrogen production, it is widely used because of its relatively low cost and mature equipment. However, in the traditional alkaline water electrolysis for hydrogen production process, the distribution and fluidity of the electrolyte have a direct impact on the electrolysis efficiency and the reaction activity on the electrode surface. At present, most electrolytic cell designs have problems such as uneven electrolyte flow and insufficient utilization of active substances on the electrode surface, resulting in low electrolysis efficiency and high power consumption.

[0003] In addition, the fixity of the electrode position limits the flexibility during the electrolysis process.
