Abstract
The solid fuel cell electrolyte is characterized by using cerium dioxide or ion-doped cerium dioxide and inorganic salt and mixing them to form two-phase or multi-phase composite material, which possesses the advantages of greatly reduced cost and raised cell efficiency by several times.
Description
technical field [0001] The invention relates to an electrolyte material for a solid fuel cell. Background technique [0002] The research on solid fuel cells began in 1900 when Nernst discovered the high-temperature oxygen ion conduction of zirconia. In the 1930s, scientists conducted research on solid fuel cells based on zirconia electrolytes. Traditional solid fuel cells are limited by doped zirconia materials, and require a high temperature of nearly 1000 ° C; high-temperature materials are used, and the price is high. In order to reduce costs, the current research trend of solid fuel cells in the world is to achieve medium temperature, that is, the temperature range is: 400-800°C. Contents of the invention [0003] The purpose of the present invention is to provide a novel composite ceramic electrolyte material for a medium-temperature fuel cell that can greatly reduce the cost of a solid oxide fuel cell and simultaneously improve the performance of the fuel cell. ...
