Problems solved by technology

Once a point on the sealing ring fails, the entire sealing system will collapse
Moreover, due to the need to add grooves to fix the sealing ring, all the structural parts that the mass transfer passage passes need to be provided with sealing grooves on the periphery of the passage, which increases the processing cost of the electrolytic cell
In addition, there are many auxiliary parts in this patent, and additional conductive plates and buffer plates are required, which further increases the volume and weight of the electrolytic cell
The patented anode uses carbon paper as the collector layer, and the oxygen-rich and high-potential environment of the anode can easily corrode the carbon paper, resulting in failure of the electrode material

Abstract

The invention discloses an electrolysed water hydrogen production electrolytic bath structure of solid polymer electrolyte (SPE), wherein the structure mainly comprises a mass transfer passage structure and a sealing structure of an electrolytic bath system. The mass transfer passage design is mainly for working medium transmission passages of positive and negative two poles of the electrolytic bath; the sufficient water supply to the positive pole of the electrolytic bath is guaranteed; hydrogen on the negative pole and oxygen and water on the positive pole can be smoothly output; meanwhile, the independence between the passages on the positive and negative poles is guaranteed; and mass transfer paths are not interfered mutually. The sealing structure is mainly for the sealing piece design in a working medium transmission area in an electric pile structure of the electrolytic bath; and the sealing performance of all components of the electric pile is guaranteed. The electrolytic bath can guarantee stable and efficient actuation of the electrolysis process, is higher in electrolysis efficiency and safety, and reduces the machining cost of structural parts thereof.

Description

technical field [0001] The invention belongs to the field of new energy, and relates to the technology of producing hydrogen by electrolyzing water, in particular to an electrolysis device for a solid polymer electrolyte (SPE) electrolyzer. Background technique [0002] As the world's energy issues become more and more urgent, hydrogen energy has attracted great attention from the academic community due to its clean, efficient, and stable characteristics. Hydrogen energy is a secondary energy source, which can act as a storage medium for traditional new energy such as wind energy and solar energy. It can effectively store the electrical energy converted from these unstable traditional energy sources through hydrogen energy, and then convert it into electrical energy and incorporate it into the grid to serve as energy conversion. buffer medium. The key to the effective use of hydrogen energy is how to solve the problem of efficient conversion of other energy sources and hydr...
