Abstract

The invention discloses a nature-imitated hematite electrolyte and a nature-imitated hematite electrolyte fuel cell, the electrolyte is composed of hematite (alpha-Fe2O3) and quartz (SiO2), compared with a traditional ion-doped electrolyte, through surface oxygen vacancy conduction of the alpha-Fe2O3 in a reducing atmosphere and the isolation effect of SiO2 on electrons, the natural-imitated hematite electrolyte has the advantages that the oxygen vacancy conduction of the surface of the alpha-Fe2O3 in the reducing atmosphere is reduced; the electrolyte has an electrolyte function, and the assembled natural hematite-imitated electrolyte fuel cell shows good output performance in a low-temperature interval, so that the natural hematite-imitated electrolyte fuel cell has a wide application prospect in the field of solid oxide fuel cells.

Description

technical field

[0001] The invention relates to the technical field of solid oxide fuel cells, in particular to an imitation natural hematite electrolyte and an imitation natural hematite electrolyte fuel cell. Background technique

[0002] Solid oxide fuel cell (SOFC) is a clean energy technology that can directly convert chemical energy stored in fuel into electrical energy. received widespread attention from the international community.

[0003] At present, the commonly used electrolytes for SOFC are doped zirconia and doped ceria. The working principle is mainly to use structural doping to generate a large number of lattice oxygen vacancies, and conduct oxygen ion conduction through the oxygen vacancy diffusion mechanism. Since this process requires high-temperature activation, this type of electrolyte can only obtain sufficient ionic conductivity at high temperatures of 800-1000 °C, which results in high SOFC manufacturing costs and technical complexity. Therefore, th...
