Abstract: A preparation method of an SOFC or SOEC with a long-life sealing interface is formed by allowing a sealing layer, a cell and a metal interconnector to be mutually contacted. In the present disclosure, with spinel as a coating material of the metal interconnector, staged thermal treatment is employed to form a high-density and strong-adhesion spinel coating to improve the endurance and entire performance of the metal interconnector. The present disclosure also optimizes the material system of the sealing layer, namely, uses the SiO2—MgO—Al2O3—SrO—V2O5 system to prepare the sealing layer, which not only improves the resistivity of the sealing layer but also increases its hardness and fracture strength. Further, under the condition of ensuring the airtightness, the coefficient of thermal expansion of the sealing layer is matched with the coefficients of thermal expansion of the metal interconnector and the cell, improving the endurance of the sealing interface.
