Description

technical field

[0001] The invention relates to a large-area anode-supported electrolyte composite membrane for a solid oxide fuel cell (SOFC) and a preparation method of a multilayer casting method, belonging to the field of material preparation technology in solid fuel cells. Background technique

[0002] SOFC is an efficient all-solid-state electrochemical energy conversion device that directly converts chemical energy into electrical energy. The power loss of its power generation is mainly concentrated in the internal resistance loss of the electrolyte material. In order to increase the current density and power density of the battery and reduce the operating temperature of the battery, while selecting a new type of electrolyte material with high conductivity, it is necessary to use a thin film preparation process for the electrolyte. As we all know, there are many preparation techniques for ceramic thin film, such as air plasma spraying (APS), electrochemical vapor dep...
