Abstract

The invention relates to a method for preparing cathode-supported tubular solid oxide fuel cells (CTS OFCs), which is characterized in that: adding an organic solvent, a dispersant, an adhesive, a pore-forming material and a plasticizer into powder of various functional layers (cathodes, anodes and electrolyte) to prepare slurry of the various functional layers; soaking a cathode supporting body, the electrolyte and an anode layer on a tubular substrate in turn, and obtaining the CTS OFCs after demolding and primary sintering; or soaking the cathode and the electrolyte, performing demolding and preburning, soaking the anode layer on the outside of the electrolyte, and obtaining the CTS OFCs through co-sintering. The method has simple technological process and low manufacturing cost, and can realize the densification of the electrolyte at a low temperature of between 1,200 and 1,300 DEG C, and the obtained cells have superior performance and good industrialization prospect.

Description

technical field

[0001] The invention belongs to the technical field of solid oxide fuel cell manufacturing, in particular to a preparation method of a cathode support tube type solid oxide fuel cell. Background technique

[0002] Solid oxide fuel cell (SOFC) is an electrochemical device that directly converts chemical energy in fuel into electrical energy. It has the characteristics of high efficiency, low pollution, and no noise. It can provide high quality power supply. The successful application of this technology is of great significance to alleviating the energy crisis, meeting the demand for power quantity and quality, protecting the ecological environment and national security.

[0003] Currently, the two most important structural types of SOFC are tube type and flat plate type. The main feature of tubular SOFC is that it does not involve the technical problem of high-temperature sealing, and the tubular structure has strong stress resistance characteristics and is ...
