Description

High-efficiency water electrolysis hydrogen production catalytic pole piece production line and application thereof
Technical Field
The application relates to the technical field of electrolytic water electrode plate manufacturing, in particular to a high-efficiency electrolytic water hydrogen production catalytic electrode plate production line and application thereof.
Background
The hydrogen energy is a secondary energy source with rich sources, green low carbon and wide application. The electrode plate for hydrogen production by water electrolysis/oxygen catalysis is a key link of the hydrogen production technology by water electrolysis, and the manufacturing cost and the hydrogen production efficiency of the electrode plate have decisive significance on the hydrogen production cost.
At present, an electrolytic tank used in a hydrogen production system in the domestic market is mainly an alkaline electrolytic tank, an electrode plate of a core component is divided into an anode plate and a cathode plate and is respectively used for catalyzing hydrogen production and oxygen production, wherein a very key procedure in the production process of the anode plate is that a catalyst is grown on a base material through an in-situ growth process, and a very key procedure in the production process of the cathode plate is electrodeposition, wherein the electrodeposition refers to selective deposition of metal at a cathode of an electrode, insoluble substances are taken as an anode, so that metal ions in electrolyte are deposited on the cathode to form a negative electrode plate with catalytic performance; at present, most electrode plates on the market use nickel screens as base materials, and the manufacturing process is carried out by immersing coiled materials. However, the electrode plate produced by the method has smaller size, thicker electrode plate, low hydrogen production efficiency, strong metal, high strength, rough processing process and poor flatness of the product. Along with the continuous increase of the hydrogen energy demand in the market, the manufacturing cost of the hydrogen energy becomes a key link, so that the current market has higher and higher requirements on the hydrogen production efficiency of the electrode plate.
In order to improve the hydrogen production efficiency, on the one hand, the size of the electrode plate can be increased, and on the other hand, the hydrogen production amount per unit area of the electrode plate can be increased. According to the mode, the electrode plate is enlarged and thinned, the structure is not flat any more, and the catalytic performance in the unit range can be higher. As the electrode sheet is increasingly larger in size, the material of the substrate is changed, and the substrate is thin (the thickness is in millimeter level, for example, 0.5 mm) and is between metal and nonmetal, such as foam nickel, but the flatness of the substrate is difficult to control during the production and processing, so that the consistency of the electrode sheet produced by the substrate is difficult to ensure. Meanwhile, in the production process of the negative electrode sheet, besides the electrodeposition, the processes of feeding, dosing, cleaning and the like are also carried out, so that a series of operations such as transferring, horizontally changing to be vertical and the like are also needed on a production line for the base material, and the large and thin sheet is a product which is inconvenient to take and put alone or is easy to transfer, so that the automatic production is difficult to realize.
