Abstract
Solid oxide fuel cell (SOFC) is a kind of all solid-state power generation equipment with high energy conversion efficiency, friendly environment and flexible fuel, which provides a choice for the sustainable development of energy resources. Oxygen ions are conducted through oxygen vacancies in solid electrolyte. Increasing the concentration of oxygen vacancy is the key to improve the ionic conductivity, and electrolyte materials with high ionic conductivity promote the development of SOFC. In this paper, the ion transport mechanism of solid electrolyte and the structure, research progress, advantages and disadvantages of ZrO2 based electrolyte, CeO2 based electrolyte, Bi2O3 based electrolyte and LaGaO3 based electrolyte materials are reviewed. The development trend of electrolyte materials in the future is prospected.
