Abstract

The invention provides a preparation method of a solid oxide fuel cell stack. A fuel cell power generation tube body group is arranged in a cathode shell; the fuel cell power generation tube body group is composed of fuel cell power generation tube bodies; a cathode gas inlet tube and a cathode gas outlet tube are arranged between the cathode shell and fuel cell power generation tube bodies; the upper end of the fuel cell power generation tube body group is provided with a fuel cell anode gas path upper joint, and the lower end of the fuel cell power generation tube body group is provided with a fuel cell anode gas path lower joint; the contact between the outer side of each fuel cell power generation tube body and the cathode shell is provided with a cathode terminal; and the contact between the inner side of each fuel cell power generation tube body and the cathode shell is provided with an anode terminal. The sintering-integrated ceramic structure of the fuel cell stack avoids the problem of difficulty in sealing of the solid oxide fuel cells under high-temperature working conditions, so that the solid oxide fuel cells can be further assembled and constructed more easily.

Description

[0001] The application of the present invention is a divisional application of the parent application "a tubular solid oxide fuel cell stack and its preparation method". The application number of the parent application is 2015107246793, and the application date is October 29, 2015. technical field [0002] The invention relates to the technical field of fuel cells, and more specifically relates to a tubular solid oxide fuel cell stack 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 ...
