Abstract

The invention discloses a tube-type solid oxide fuel cell monocell and a preparation method thereof. In the tube-type monocell, a fuel cell generation tube body is arranged in a cathode shell, a cathode air inlet tube and a cathode air outlet tube are arranged between the cathode shell and the fuel cell generation tube body, an upper connector of the fuel cell generation tube body is arranged at the upper end of the fuel cell generation tube body, a lower connector of the fuel cell generation tube body is arranged at the lower end of the fuel cell generation tube body, and a cathode binding post and an anode binding post are arranged at a position where the fuel cell generation tube body and the cathode shell are in contact. With the adoption of a ceramic sealing sintering technique, all components of the fuel cell monocell are sealed and sintered to form an integrated ceramic structure, the problem of difficulty in sealing of all components of the solid oxide fuel cell in a high-temperature working condition is avoided, and the solid oxide fuel cell is further easy to assemble and build.

Description

technical field [0001] The invention relates to the technical field of fuel cells, and more specifically relates to a single tubular solid oxide fuel cell and a preparation method thereof. Background technique [0002] With the development of economy and society, human beings are facing more and more pressing environmental and energy issues. A fuel cell is a high-efficiency power generation device that directly converts the chemical energy of fuel into electrical energy without going through a heat engine process, so its efficiency is not limited by the ideal efficiency of the Carnot cycle. The research on fuel cells has a history of hundreds of years, and people have invented many kinds of fuel cells. Among them, the solid oxide fuel cell (SOFC) has received great attention. At present, the power generation efficiency of a solid oxide fuel cell single cell can reach 50%, and the power generation efficiency of combined cycle power generation with a steam turbine can reach ...
