Abstract

The invention discloses a preparation method of a tubular solid oxide fuel cell monocell; a fuel cell power generation tube body is arranged in a negative electrode outer shell, a negative electrode gas inlet tube and a negative electrode gas outlet tube are arranged between the negative electrode outer shell and the fuel cell power generation tube body; the upper end of the fuel cell power generation tube body is provided with a fuel cell power generation tube body upper connector, the lower end of the fuel cell power generation tube body is provided with a fuel cell power generation tube body lower connector, and a negative electrode binding post and a positive electrode binding post are arranged at positions where the fuel cell power generation tube body upper connector makes contact with the negative electrode outer shell. All fuel cell monocell parts are sealedly sintered into a ceramic integral structure by a ceramic seal sintering technology, the problem that parts of a solid oxide fuel cell are difficult to seal under high temperature working conditions is solved, and further assembly and construction of the solid oxide fuel cell are easier.

Description

[0001] The application of the present invention is a divisional application of the parent application "a single tubular solid oxide fuel cell and its preparation method". The application date of the parent application is July 22, 2015, and the application number is 2015104354743. technical field [0002] 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 [0003] 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 c...
