Description
Technical Field
The invention relates to the technical field of high-temperature sealing materials, in particular to a high-temperature composite sealing material and a preparation method and application thereof.
Background
The Solid Oxide Fuel Cell (SOFC) is a power generation device which adopts solid oxide as an electrolyte membrane and converts chemical energy of fuel into electric energy efficiently and cleanly through electrochemical reaction, the power generation efficiency can reach more than 50 percent, the cogeneration efficiency is higher than 80 percent, and the SOFC is a high-efficiency power generation device for reducing carbon dioxide emission. The solid oxide fuel cell can use not only hydrogen fuel but also natural gas, liquefied petroleum gas, methanol, ethanol, biomass gas and the like which are abundant in resources and cheap as fuels. The single cell of the solid oxide fuel cell consists of an anode, a cathode and an electrolyte, the working temperature is usually 600-1000 ℃, the single cell is usually low in voltage and low in output power, and a plurality of single cells need to be assembled into a stack to obtain high output power so as to meet the requirements of practical application. In solid oxide fuel cell systems, the primary function of the sealing material is to ensure that oxygen and fuel gas do not mix and leak outward, providing a reliable seal, which requires good gas tightness of the sealing material to prevent danger, and high temperature sealing is therefore of great importance. At the same time, it also has good thermal matching and chemical compatibility with adjacent components, long-term stability in oxidizing and reducing atmospheres, and the like. This makes the high temperature sealing problem one of the major factors that limit its development.
At present, the sealing realized by viscous flow of glass or glass ceramics material at high temperature is a relatively stable and suitable sealing mode of the solid oxide fuel cell. The single batteries and the connecting body are adhered together through glass sealing to form a galvanic pile; isolating air from fuel; the electric insulation between the single cell and the connecting body is maintained. However, in a hydrogen atmosphere, long-time (80000 h) high-temperature operation (600-1000 ℃) and frequent cold-hot cycle repeated start, a single glass sealing material is difficult to meet the requirements. The stability and the durability of the sealing are determined by the evolution of the performance of the sealing material and the compatibility and the stability of the sealing interface of other parts, and researches find that the sealing failure of the sealing material in the operation process of the galvanic pile is mainly caused by two reasons, namely that the glass material is difficult to maintain the long-term structure unchanged due to the fluidity at high temperature, and the brittle cracking of the sealing material and the delamination cracking of the sealing interface are realized. Therefore, a sealing material is needed to solve the problems of long-term stability of the sealing material of the solid oxide fuel cell and delamination cracking of the sealing interface.
