Abstract

The invention provides a cell stack of tubular solid oxide fuel cells and a preparation method of the cell stack. A fuel cell power generating tube body group is arranged in a cathode casing and consists of fuel cell power generating tube bodies; a cathode air inlet pipe and a cathode air outlet pipe are arranged between the cathode casing and the fuel cell power generating tube bodies; a fuel cell anode air path upper joint is arranged at the upper end of the fuel cell power generating tube body group; a fuel cell anode air path lower joint is arranged at the lower end of the fuel cell power generating tube body group; a cathode terminal is arranged at the contacting part of the outer side of each fuel cell power generating tube body and the cathode casing; an anode terminal is arranged at the contacting part of the inner side of each fuel cell power generating tube body and the cathode casing. The cell stack of the fuel cells is sintered into an integrated ceramic structure, so that the problem that the solid oxide fuel cells are difficult to seal under high-temperature working conditions is avoided, and further assembly and construction of the solid oxide fuel cells are realized more easily.

Description

technical field [0001] 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 [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 solid oxide fuel cells can reach 50%, and the power generation efficiency of combined cycle power generation with steam turbines can reach 70%. Further ra...
