Description
Technical Field
The invention relates to the technical field of solid oxide fuel cells based on perovskite electrolytes.
Background
The world energy demand is continuously increasing, and fossil energy such as petroleum, coal and natural gas, as the most important energy resource in the world at present, brings convenience and wealth to people and also brings two problems: energy crisis and environmental pollution. These issues drive the scientific field to develop more efficient, clean and low cost energy or energy production and conversion systems, making the development and research of new energy and high-efficiency energy conversion systems an active field of scientific research.
In the field of new energy, fuel cells have an important place, and are considered to be one of the most promising products for replacing traditional fossil energy power generation, chemical energy can be directly converted into electric energy without combustion, and the conversion breaks through the limit of carnot cycle. Fuel cells are generally composed of three components: an electrolyte, a cathode and an anode, wherein the selection of the electrolyte material determines the type of fuel cell, the operating temperature and the energy conversion efficiency. Among the existing Fuel cells, Solid Oxide Fuel Cells (SOFC) in which the electrolyte is a Solid Oxide have attracted attention because of their unique advantages and characteristics. As an all-solid-state power generation device capable of efficiently and environmentally converting chemical energy stored in fuel and oxidant into electric energy, the energy conversion efficiency can reach 50-80%. In existing SOFCs, Yttrium Stabilized Zirconia (YSZ) can be considered as the most classical electrolyte material for solid oxide fuel cells, which is chemically stable under an oxygen-hydrogen atmosphere, has high ionic conductivity, and excellent performance output. On the other hand, the high ionic conductivity of YSZ and similar SOFCs can only be achieved at high temperature (1000 ℃), which results in a series of new problems, such as greatly increased performance requirements for battery mating materials, increased battery cost, increased battery sealing difficulty, and easy occurrence of electrode sintering, interface diffusion between electrolyte and electrode, and thermal expansion mismatch. After several decades of development of SOFCs, researchers in various countries around the world wish to further reduce the manufacturing cost of each component and the operating cost of a battery by reducing the operating temperature thereof, and to realize medium-temperature (500 ℃ -800 ℃) and even low-temperature (less than 500 ℃), so that development of electrolyte materials having high ionic conductivity at medium and low temperatures is increasingly demanded.
After the electrolyte material is developed, the electrolyte material can be really applied to the fuel cell by considering the performances of chemical compatibility, thermal expansion coefficient matching and the like among component materials, so that the phenomena of thermal cracking of the cell, serious reduction of electrochemical performance and the like caused by mutual reaction and inconsistent thermal expansion can be avoided.
