ELECTROLYTE MEMBRANE, ELECTROCHEMICAL DEVICE AND SOLID OXIDE FUEL CELL

摘要

The present invention relates to an electrolyte membrane, an electrochemical device and a solid oxide fuel cell which comprise said electrolyte membrane. Said electrolyte membrane includes at least one strength reinforcing electrolyte membrane layer and at least one high ionic conductivity electrolyte membrane layer, wherein the bending strength of said strength reinforcing electrolyte membrane layer is more than 300MPa, and the ionic conductivity at 800? of said high ionic conductivity electrolyte membrane layer is more than 0.03 S/cm. The strength reinforcing electrolyte membrane layer can enhance the strength of the electrolyte membrane, and the high ionic conductivity electrolyte membrane layer can improve the electrical properties of the electrolyte membrane,thus the electrolyte membrane of the present invention can meet the requirements of strength and electrical property.
