Electrolytic tank with efficient turbulent flow multi-connecting-hole turbulent flow elements

Abstract

The invention relates to an electrolytic bath with an efficient turbulent flow multi-connecting-hole turbulent flow element, which has a structural mode of increasing the contact area of electrolyte and a polar plate in an electrolytic hydrogen production process, and has the characteristics of shortening the path of the electrolyte in the electrolytic bath, reducing resistance, improving a flow field, reducing energy consumption and ensuring reliable and normal operation of the electrolytic bath. The invention relates to an electrolytic bath with efficient turbulent flow multi-connecting-hole turbulent flow elements. The electrolytic bath is characterized by at least comprising an end polar plate, a middle polar plate, a left (right) side bipolar plate and a supporting diffusion layer. The technical problem to be solved is to provide the supporting diffusion layer of the multi-connecting-hole turbulent flow element with the turbulent flow effect in the polar plate of the water electrolyser aiming at the defects in the prior art.

Description

technical field [0001] The invention relates to an electrolytic cell with high-efficiency turbulent flow multi-connected hole turbulence elements, which belongs to the technical field of hydrogen production by electrolysis of water, and specifically relates to a structural method for increasing the contact area between an electrolyte and a pole plate in the process of hydrogen production by electrolysis of water. Background technique [0002] In recent years, hydrogen energy, as a new type of green energy, has attracted more and more attention worldwide. Since solar energy, wind energy, and nuclear energy are widely used for power generation, the cost of electrolytic hydrogen production will continue to decline, especially in today's rapid growth of wind power and photovoltaic installed capacity, and "zero pollution" in the hydrogen production process can be achieved. It is foreseeable that low-cost, high-efficiency water electrolysis hydrogen production will be one of the c...

Problems solved by technology

The water electrolyzer is the core equipment in the hydrogen production device. The large-scale water electrolyzer will inevitably increase the number of electrolysis cells. The increase of the electrolysis cells will cause the uniformity of the flow field in the electrolysis cell to deteriorate, and the temperature difference between the electrolysis cells will increase. The resistance to liquid flow increases, and the operating state of the electrolyzer deteriorates. These unfavorable factors will affect the development of large-scale water electrolyzers.
