Abstract

The invention relates to an A-site defect type perovskite structure fuel cell electrolyte, a preparation method thereof and a fuel cell, the chemical formula of the electrolyte is Ba < 0.9 > Co < 0.4 > Fe < 0.4 > Zr < 0.1 > Y < 0.1 > O < 3-delta > (BCFZY < 0.9 >), and the electrolyte is an ABO < 3-delta > type perovskite structure material. According to the invention, the ionic conductivity and the electrolyte function are obviously improved through an A-site defect method, and good low-temperature output performance is shown in a fuel cell taking Ni0. 8Co0. 15Al0. 05LiO2-delta (NCAL) permeated foamed nickel as a symmetrical electrode. Compared with the traditional pure ion conduction type electrolyte, the electrolyte provided by the invention is an oxygen ion / proton / electron mixed conduction type semiconductor and shows good ionic conductivity in a low-temperature interval, so that the electrolyte has an important application prospect in a low-temperature solid oxide fuel cell system.

Description

technical field [0001] The invention relates to the technical field of solid oxide fuel cells, in particular to an A-site defect type perovskite structure fuel cell electrolyte, a preparation method thereof, and a fuel cell. Background technique [0002] Solid oxide fuel cell (SOFC) is a power generation device that directly converts the chemical energy of hydrogen-based fuel into electrical energy. Because it bypasses the traditional heat engine Carnot cycle, its theoretical efficiency can reach 60%, and it has The advantages of high energy conversion efficiency, low pollution and fuel diversity. As a result, fuel cells have gradually become the focus and hot spot in the field of new energy in recent years. [0003] However, the high operating temperature of SOFC has limited its application. Traditional SOFC usually needs to work at 800-1000°C, which will increase operating costs and shorten battery life. How to solve these problems has become the main problem in the com...
