Abstract
A method for producing an electrolyte matrix for a fuel cell, especially a molten carbonate fuel cell, the method comprising mixing components which comprises a dispersant, at least one lithium compound, aluminum oxide, and zirconium carbide, to provide a matrix material. Fuel cells produced with the disclosed electrolyte matrix do not form cracks due to the differences in thermal expansion coefficients between the matrix and the surrounding metallic components, and thus have improved performance and service life. Also disclosed are the electrolyte, the matrix, and the fuel cell so produced.
