Problems solved by technology
[0005] Both the fuel cell and the electrolytic cell include multiple battery units, and each battery unit includes a structure such as a porous plate and a connecting plate. When making an existing battery unit, each part of the battery unit is generally made separately, and then each part is connected. This process requires multiple high-temperature sintering, the efficiency is extremely low, and the sintering process is extremely sensitive to factors such as temperature and atmosphere, so the yield of the traditional preparation process is extremely low, and the cost of the battery prepared by it is therefore high.

Abstract
The invention relates to the technical field of electrochemical reaction, and discloses a method for manufacturing an electrochemical reaction device. Firstly, a unit model of a battery unit is set, and then a plurality of support units are manufactured by using additive manufacturing technology and according to the unit model, and each support unit is Coating the first electrode layer, the electrolyte layer and the second electrode layer to obtain the battery unit, and then continuing to coat the first sealant layer around the second electrode layer, and then stacking a plurality of battery units in sequence to form a stack, the stack Perform one-time sintering. The invention adopts the additive manufacturing technology to manufacture the support unit in a flat plate type, and the support unit is integrally formed, the process is simple, and the production efficiency of the electrochemical reaction device is greatly improved, and the production efficiency of the support unit is 4-200 times that of the traditional process; in addition In the present invention, a plurality of battery units are stacked before one-time sintering, and the electrochemical reaction device can be completed by one-time sintering, the process is simple, and there is no need to repeatedly sinter a single battery unit.
Description
Technical field [0001] The present invention relates to the field of energy technologies, and more particularly to a method of fabricating an electrochemical reaction apparatus and an electrochemical reaction device. Background technique [0002] The electrochemical reaction device includes a fuel cell and an electrolytic cell. [0003] The fuel cell and electrolytic cells are energy conversion devices, which distinguish that the fuel cell can convert chemical energy to electrically, and the electrolytic cell can convert electrolytic energy into electrolyte gas chemical energy. [0004] Generally, the solid oxide fuel cell and the electrolytic cell include an anode, cathode, and electrolyte. Among them, when the fuel cell is operating, the first reactant and the second reactant are supplied by the outside, and the first reactant is lost in the anode, while the second reactant is electronically electronically, electrons are electronically generated from the anode to the cathode, t...
