Problems solved by technology

[0004] However, as far as the solid oxide fuel cell / electrolytic cell is concerned, there are still many technical problems that have not been effectively resolved in the production and preparation process.
For example, the existing production process is mostly manual operation or staged operation, and this type of operation has high manual error, complex operation procedures, low degree of mechanization and automation, low battery yield rate, and difficult to control the stability of battery performance, etc. question
Not only that, the production technology of solid oxide fuel cells / electrolyzers supported by porous metals is rarely mentioned in this field; moreover, how to produce solid oxide fuel cells / electrolytic cells supported by porous metals The problems of improving its yield and maintaining battery stability during the preparation process have not been effectively resolved so far.

Abstract

The invention provides a method and system for continuously producing a cell / electrolytic cell and the cell / electrolytic cell. The method comprises the step of sequentially preparing an anode (hydrogen electrode) layer, an electrolyte layer and a cathode (oxygen electrode) layer on a metal porous thin plate supporting body. The method provided by the invention comprises the steps of firstly, taking a metal porous thin plate as a pressure-bearing supporting body in a continuous production line, then regulating and controlling the thickness of an anode (hydrogen electrode) layer, selectively removing a solvent and part of a binder in an electrolyte slurry layer, and carrying out pressure sintering densification treatment on an electrolyte layer, thereby solving problems that the automation degree is low, the yield is low, and the performance stability is poor in the technology of continuously producing the solid oxide fuel cell / electrolytic cell supported by the metal sheet. Therefore, according to the method provided by the invention, the continuous production of the solid oxide fuel cell / electrolytic tank can be realized, the production process is simplified, the production efficiency and the yield are improved, and the method has a wide commercial application prospect.

Description

technical field [0001] The invention relates to the technical field of solid oxide fuel cell production equipment, in particular to a method, system and battery / electrolytic cell for continuous production of batteries / electrolytic cells. Background technique [0002] As a new energy conversion device, the fuel cell can maximize the conversion of chemical energy into electrical energy because it is not affected by the Carnot cycle. It has higher power generation efficiency. In addition, the common raw materials of fuel cells are fuel and oxygen, with high fuel conversion efficiency and less harmful gas emissions, which is in line with national sustainable development and environmental protection requirements. Due to its excellent portability and good stability, fuel cells are expected to be widely used in stationary power stations, portable power generation devices, and transportation.
