Abstract

The invention discloses a manufacturing method for an anode plate of a water electrolyte device; the manufacturing method comprises the following steps of: (1) by using a nickel plate as a baseplate, placing the baseplate in a mixing solution of nickel sulfamic acid, LaNi5H6 and 4-methoxyphenyl porphyrin in pressurized equipment for pressurized soaking reaction; (2) taking out and cleaning the nickel plate, and then electroplating the nickel plate in a cerium chloride solution; and (3) adding nickel sulfate hexahydrate, sodium citrate and ammonium sulfate to the cerium chloride solution in the step (2) so as to adjust the pH of the solution to be 3-7, and electroplating the baseplate again to obtain the anode plate. The catalytic electrolysis effect of water molecules of the anode in water electrolysis is equivalent to that of the traditional electrode manufactured by rare metals such as platinum and the like. According to the manufacturing method, the anode plate can be manufactured by using raw materials with lower cost, is low in cost and is beneficial to the wide popularization and application.

Description

technical field [0001] The invention relates to the field of anode plates, and more specifically, relates to a method for manufacturing an anode plate of a water electrolysis device. Background technique [0002] Water electrolysis, which splits water into its constituent elements oxygen and hydrogen, is a very important method not only for the production of oxygen and / or hydrogen, but also for energy storage. Energy is consumed when water is decomposed into hydrogen and oxygen, and energy is released when hydrogen and oxygen are reconnected to form water. Therefore, the technology of water electrolysis to produce hydrogen and / or oxygen has played an important role in various fields of military and civilian industries, and is widely used Used in electronics, chemical industry, metallurgy, glass, electric power, meteorology and other departments. [0003] The traditional water electrolysis plates use platinum and other rare metals as electrodes, which have the purpose of cat...
