Description

Electrolysis water film electrode preparation positioner Technical Field The utility model relates to the technical field of electrolytic water, in particular to a positioning device for preparing an electrolytic water film electrode. Background PEM water electrolysis hydrogen production technology utilizes a Proton Exchange Membrane (PEM) to split water into hydrogen and oxygen. The technology has the characteristics of high efficiency and environmental protection, and is suitable for small-scale distributed hydrogen production. The membrane electrode has the function of separating water into hydrogen and oxygen electrochemical reaction sites in the hydrogen production by the electrolysis of water through the proton exchange membrane. The membrane electrode structure consists of 5 parts, namely two side frames, a proton exchange membrane, an anode catalytic layer and a cathode catalytic layer. The proton exchange membrane is positioned at the center, and anode and cathode catalytic layers (both containing expensive noble metals and having high price) are respectively coated on two sides of the proton exchange membrane, which is called CCM. The rims, called MEAs, are then encapsulated on both sides of the CCM. The frame has the functions of enhancing the mechanical property of the membrane electrode, supporting CCM, improving the air tightness of the membrane electrode and replacing part of proton exchange membrane, thereby reducing the use of the proton exchange membrane and the cost of the membrane electrode. When the CCM is prepared by the transfer printing method, the first layer is an anode (or cathode) catalytic layer, the second layer is a proton exchange membrane, the third layer is a cathode (or anode) catalytic layer, the three layers of materials are sequentially stacked together, and the CCM is formed by hot pressing transfer printing, if the anode and the cathode are misplaced, the effective utilization area of the catalytic layer is reduced, and therefore the water electrolysis efficiency is reduced. The traditional alignment method is that light irradiates from top to bottom, and as materials are stacked from bottom to top, the material of the middle layer shields the sight of the material of the lower layer, so that dislocation is easy to occur when the material of the upper layer is placed.
