Abstract
The present application relates to a method of manufacturing an anode supporter of a solid oxide fuel cell and an anode supporter of a solid oxide fuel cell, and may improve performance and durability of the fuel cell by improving an interfacial property between the anode supporter and an electrolyte.
Claims8
A method of manufacturing an anode supporter and electrolyte of a solid oxide fuel cell, the method comprising:
- surface-treating at least one sintered surface of the anode supporter including a metal and an inorganic oxide having oxygen ion conductivity by using a ceramic bead blast method until the at least one sintered surface has an Ra of from −1AQ-500 to 900 nanometers and a surface area of the at least one sintered surface is increased by 1.5 times or more and 10 times or less:
- and
- applying an inorganic oxide having ion conductivity on the treated surface of the anode supporter to form an electrolyte,
- wherein the ceramic beads are chosen from gadolinium doped ceria (GDC), gadolinium doped zirconia (GDZ), samarium doped ceria (SDC), samarium doped zirconia (SDZ), yttrium doped ceria (YDC), yttrium doped zirconia (YDZ), yttria stabilized zirconia (YSZ), and scandia stabilized zirconia (ScSZ).
