Abstract

The invention discloses a large-size tubular solid oxide fuel cell and a preparation method thereof, and the method comprises: powder material of each functional layer of a solid oxide fuel cell is respectively added with an organic solvent, a dispersant, an adhesive and a plasticizer, and fully ground to obtain a uniform support anode slurry, an active anode slurry, an electrolyte slurry, an active cathode slurry and an electricity-receiving cathode slurry. The outer surface of a mold is impregnated with the support anode layer by layer after the vacuum treatment; the support anode tube is filled with combustible organic matter after demoulding; the active anode and the electrolyte are impregnated to form a support anode / active anode / electrolyte composite membrane; then the external side of the electrolyte is impregnated with the active cathode and the electricity-receiving cathode after sub-temperature sintering, that is, after pre-burning and high-temperature sintering; and the large-size tubular solid oxide fuel cell is obtained after sintering. The invention has advantages of simple process, low manufacturing cost, achieving good-performance large-size tubular solid oxide fuel cell and good prospect of industrialization.

Description

technical field

[0001] The invention relates to a large-size tubular solid oxide fuel cell and a preparation method thereof, belonging to the technical field of fuel cell manufacturing. Background technique

[0002] Solid oxide fuel cell (SOFC) is a high-efficiency all-solid-state electrochemical energy conversion device that directly converts chemical energy into electrical energy. Three generations of generators. The solid oxide fuel cell has the advantages of its all-solid-state structure, no corrosion, no leakage, high efficiency, modular design, and wide range of fuel applications, and it is suitable for combined heat and power (efficiency can reach 70%-80%) It has become a hot spot and focus in fuel cell technology. Solid oxide fuel cells mainly have two structures, flat plate and tubular. Compared with flat solid oxide fuel cells, the advantages of tubular solid oxide fuel cells are easy sealing, strong thermal shock resistance, and rapid response to loads. , the s...
