Abstract

The invention discloses a three-chamber, two-power-source fully decomposed water electrolysis device, which includes a cylindrical electrolytic cell and two electrochemical workstations. The cylindrical electrolytic cell is divided into three groups of fan-shaped electrolytic cells by three groups of partition plates, and the three groups of electrolytic cells are respectively chamber a. , room b, room c, one working electrode and two reference electrodes are placed in room a, one counter electrode is placed in room b and room c respectively; the working electrode adopts copper oxide nanometer self-supporting electrode based on copper wire. The invention also discloses the use method of the device. The a-c loop potential is set at any potential between +0.85V and +1.25V; the a-B loop potential is set at any potential between 0.00V and +0.21V. The device can generate hydrogen in chamber c and oxygen in chamber b. This invention breaks through the bottleneck of high energy consumption that has restricted industrial water electrolysis for hydrogen production for many years, will change the design ideas of traditional water splitting equipment and electrodes, develop a new design scheme for industrial electrolyzed water, and save a lot of hydrogen and oxygen for industrial water splitting. investment and operating costs.

Description

technical field [0001] The invention belongs to the technical field of catalyst decomposing water to prepare hydrogen and oxygen, and in particular relates to a three-chamber two-power fully decomposing water electrolysis device and method. Background technique [0002] Due to its high calorific value, hydrogen itself is non-toxic, and the product of combustion is water, which is non-polluting. It is an ideal substitute for fossil energy. Pure oxygen plays a very important role in chemical industry such as steelmaking, defense industry, medical care and other fields. Therefore, it will be one of the preferred ways to solve the energy crisis and reduce the cost of industrial fields involving hydrogen / oxygen as fuel / raw material to realize the production of hydrogen and oxygen by splitting water with electric energy consumption. [0003] At present, the anode materials in the electrolyzers for electrolyzing water in the industry usually use noble metals Pt, Ir, Ru and their b...
